1 00:00:07,170 --> 00:00:12,020 You guys this is Caleb with Dev slopes and in this video we're going to set up an instance of a speech 2 00:00:12,020 --> 00:00:15,750 synthesizer to speak what we see in our images. 3 00:00:15,740 --> 00:00:17,010 It's going to be really cool. 4 00:00:17,120 --> 00:00:22,490 And when I initially thought of this idea I thought of it as a way to be kind of like an assistive technology 5 00:00:22,910 --> 00:00:25,070 perhaps to those who are vision impaired. 6 00:00:25,070 --> 00:00:29,990 If they if they can't see what is in front of them they could use our app to scan things and it could 7 00:00:29,990 --> 00:00:34,340 speak it to them so they could hear what they're seeing so kind of like they can see with their ears 8 00:00:34,610 --> 00:00:35,440 supercool. 9 00:00:35,780 --> 00:00:39,590 And actually to use Avie speech synthesizer is not very difficult. 10 00:00:39,830 --> 00:00:45,020 So I just want to show you how to use it and how I use that in this app so pull open that X code project 11 00:00:45,410 --> 00:00:51,890 and let's go ahead and let's begin by actually creating an instance of a speech synthesizer. 12 00:00:51,890 --> 00:00:56,640 So go ahead and type var speech synthesizer. 13 00:00:57,350 --> 00:01:03,410 And that's going to be of type Avie speech synthesizer can instantiate it. 14 00:01:03,410 --> 00:01:04,640 And that's that. 15 00:01:04,640 --> 00:01:09,320 Now if you look deeply inside of this you'll notice that this comes from A-V foundation. 16 00:01:09,320 --> 00:01:13,950 So we've already integrated A-V foundation to capture our photo. 17 00:01:14,060 --> 00:01:20,270 But the part of A-V stands for audio and that's where our Avies speech synthesizer will come into play. 18 00:01:20,270 --> 00:01:28,160 OK now what we do need to do for this to work is we need to set the speech synthesisers delegate to 19 00:01:28,160 --> 00:01:30,040 be this view controller. 20 00:01:30,230 --> 00:01:35,380 So go ahead and type speech synthesizer dot delegate and that equals self. 21 00:01:35,390 --> 00:01:41,830 Now if we try to build and run this there is an error cannot assign value of type camera AVC to A-V 22 00:01:41,840 --> 00:01:44,300 speech synthesizer delegate. 23 00:01:44,300 --> 00:01:51,220 Now to fix that we're going to create an extension of A-V speech synthesizer delegate. 24 00:01:51,340 --> 00:01:55,690 That's going to give us the ability to call some important delegate methods that we need. 25 00:01:55,730 --> 00:01:59,560 So go ahead and type extension camera AVC. 26 00:01:59,780 --> 00:02:03,550 And we're going to do Avies speech synthesizer delegate. 27 00:02:03,950 --> 00:02:04,340 OK. 28 00:02:04,430 --> 00:02:09,980 And the function we're going to call is called did finish utterance and we'll talk about that in a second. 29 00:02:09,980 --> 00:02:18,050 So just go ahead and add that function and code to finish utterance We'll come back to that in a second. 30 00:02:18,050 --> 00:02:21,080 But for now if we go back up to view. 31 00:02:21,170 --> 00:02:26,540 Whereas that view did appear you can see that air went away because now we are conforming to speech 32 00:02:26,540 --> 00:02:27,640 synthesizer delegate. 33 00:02:27,710 --> 00:02:28,710 That's all we need. 34 00:02:29,120 --> 00:02:37,970 So in order to actually speak something we need to be able to create a speech utterance to get an AB 35 00:02:37,970 --> 00:02:40,070 speech utterance to actually speak. 36 00:02:40,070 --> 00:02:41,960 We need to pass it a string. 37 00:02:41,960 --> 00:02:47,510 So we're going to create a function that basically allows us to pass a string into an avi speech utterance 38 00:02:47,540 --> 00:02:50,060 and then use our synthesizer to speak it. 39 00:02:50,060 --> 00:02:59,890 So go ahead and type phunk synthesize speech speech from string and we're gonna use an internal parameter 40 00:02:59,890 --> 00:03:01,770 they're called string. 41 00:03:02,140 --> 00:03:04,210 Of course of type string. 42 00:03:04,900 --> 00:03:10,570 And basically what we're going to do is we'll create an instance of Avies speech utterance we'll pass 43 00:03:10,570 --> 00:03:15,180 it the string and then we will ask our synthesizer to speak the utterance. 44 00:03:15,190 --> 00:03:21,270 So go ahead and type let speech utterance equals Avies speech utterance. 45 00:03:21,760 --> 00:03:25,360 And we're going to pass a string K and that's what it's going to speak. 46 00:03:25,360 --> 00:03:28,960 Now of course this is the string we're passing in. 47 00:03:28,960 --> 00:03:34,340 So go ahead and type string and it can be that lowercase string from the internal parameter. 48 00:03:34,810 --> 00:03:42,110 OK so then now that we have that utterance we can call our synthesizer K speech synthesizer speak. 49 00:03:42,130 --> 00:03:50,800 And you'll notice it asks for an example of A-V speech utterance and we have that speech whoops speech 50 00:03:51,220 --> 00:03:52,420 utterance. 51 00:03:52,420 --> 00:03:53,650 OK that's what we need to pass it. 52 00:03:53,640 --> 00:03:59,830 Now this function for any string we pass in it will speak it k. 53 00:03:59,860 --> 00:04:05,470 That's the cool thing of Avies speech synthesizer any string we pass in it's going to speak for us. 54 00:04:05,470 --> 00:04:13,720 So we need to determine when we should speak this and that is basically when we classify our results. 55 00:04:13,750 --> 00:04:18,940 So when we pull through all of our classifications if it comes to something that it has no idea what 56 00:04:18,940 --> 00:04:21,770 it is if it's not sure we should speak that. 57 00:04:21,880 --> 00:04:22,570 OK. 58 00:04:22,930 --> 00:04:27,430 Now what we're going to do is we're actually going to take this string and I'm going to go ahead and 59 00:04:27,430 --> 00:04:29,260 copy it and delete it. 60 00:04:29,530 --> 00:04:35,430 And we're going to call this let unknown object message. 61 00:04:35,830 --> 00:04:37,830 And that's what we're going to use here. 62 00:04:37,840 --> 00:04:40,040 Unknown object message. 63 00:04:40,150 --> 00:04:44,530 We're going to also use that in our synthesise speech function. 64 00:04:44,530 --> 00:04:49,330 So go ahead and call a synthesized speech from string and we're going to give it our unknown object 65 00:04:49,330 --> 00:04:50,120 message. 66 00:04:50,140 --> 00:04:54,790 Now whenever we find something that we don't know what it is it's going to say I'm not sure what this 67 00:04:54,790 --> 00:04:55,060 is. 68 00:04:55,060 --> 00:04:56,370 Please try again. 69 00:04:56,410 --> 00:05:06,340 Very cool but we need to also create a string that's going to classify our object and give a level of 70 00:05:06,340 --> 00:05:07,300 confidence. 71 00:05:07,390 --> 00:05:13,330 So to do that I'm going to go ahead and I'm going to actually create some variables for this as well. 72 00:05:13,330 --> 00:05:23,910 So I'm going to cut this and just create var identification and let's go ahead and do var confidence. 73 00:05:24,010 --> 00:05:30,760 And we're going to actually take our confidence value here as well and let's go ahead and cut that out. 74 00:05:30,790 --> 00:05:31,970 Let's put it here. 75 00:05:32,110 --> 00:05:32,710 Cut that out. 76 00:05:32,710 --> 00:05:33,880 Confidence. 77 00:05:33,880 --> 00:05:34,540 All right cool. 78 00:05:34,660 --> 00:05:37,570 So we're going to pass in the confidence that we just created. 79 00:05:37,570 --> 00:05:41,540 We're going to give this the identification as a string. 80 00:05:41,740 --> 00:05:43,360 And so that looks good. 81 00:05:43,760 --> 00:05:46,690 OK let's go ahead and make sure those little warnings go away. 82 00:05:47,160 --> 00:05:47,810 Oh OK. 83 00:05:47,830 --> 00:05:49,000 They were never mutated. 84 00:05:49,090 --> 00:05:50,800 Let's just create them in two constants. 85 00:05:50,800 --> 00:05:52,510 Good call X code. 86 00:05:52,510 --> 00:05:54,330 Always looking out for me. 87 00:05:54,340 --> 00:05:54,790 Very cool. 88 00:05:54,800 --> 00:05:55,920 OK so that's good. 89 00:05:56,170 --> 00:06:02,890 But now we need to speak what it is that we saw so let's call synthesized speech and this string what 90 00:06:02,890 --> 00:06:10,510 we're going to do is we're going to compile both of these into a nice long sentence that makes sense 91 00:06:10,510 --> 00:06:12,210 that feels like natural language. 92 00:06:12,220 --> 00:06:16,850 So let's call this complete sentence. 93 00:06:17,230 --> 00:06:22,730 And we're going to basically say this looks like a. 94 00:06:23,530 --> 00:06:27,100 And we're going to pass in the identifier or sorry the identification. 95 00:06:27,100 --> 00:06:28,770 This looks like a fish. 96 00:06:28,780 --> 00:06:31,540 This looks like a remote. 97 00:06:31,570 --> 00:06:32,830 And I'm 98 00:06:35,530 --> 00:06:38,230 and here's where we pass in our confidence. 99 00:06:38,610 --> 00:06:38,940 OK. 100 00:06:38,960 --> 00:06:41,660 I'm blank per cent sure. 101 00:06:41,680 --> 00:06:48,070 So for an example this could be this looks like a remote control and I'm 98 percent sure. 102 00:06:48,220 --> 00:06:49,320 Pretty cool. 103 00:06:49,320 --> 00:06:54,740 Now we're going to synthesize that complete sentence so that it speaks that outloud and. 104 00:06:55,000 --> 00:06:55,690 Yeah. 105 00:06:55,780 --> 00:06:56,880 So this should work. 106 00:06:56,890 --> 00:06:59,350 This should synthesize our speech. 107 00:06:59,830 --> 00:07:05,080 If we go inside Avies speech synthesizer if you look inside of it you can see it has a delegate it has 108 00:07:05,080 --> 00:07:10,540 all kinds of booleans to check to see whether or not it's speaking if it's paused it has some functions 109 00:07:10,540 --> 00:07:11,470 to speak. 110 00:07:11,710 --> 00:07:15,340 And I should have shown you that earlier but I didn't. 111 00:07:15,340 --> 00:07:20,840 You can look inside here and you can see all of the cool things that A-V speech synthesizer and Avies 112 00:07:20,840 --> 00:07:22,150 speech utterance can do. 113 00:07:22,150 --> 00:07:24,450 You can even change the voice which is kind of cool. 114 00:07:24,460 --> 00:07:27,840 There's a system default but you could turn it into a different voice. 115 00:07:28,000 --> 00:07:32,680 And we can play around with that later but for now let's go ahead and build and run this let's see if 116 00:07:32,710 --> 00:07:33,590 it works. 117 00:07:37,810 --> 00:07:40,260 OK let's pull open quick time here. 118 00:07:40,460 --> 00:07:43,030 Time using two is what I'm using to record my screen. 119 00:07:43,070 --> 00:07:47,960 If you don't know you can go into quick time and you can actually choose your iPhone as an input camera 120 00:07:47,960 --> 00:07:48,970 which is very cool. 121 00:07:49,220 --> 00:07:59,610 So anyway let's go ahead and let's tap on the screen K so it looks like it's showing the day looks like 122 00:07:59,610 --> 00:08:08,220 it's showing everything but it doesn't appear that it's speaking let's see oh you know what I bet. 123 00:08:08,230 --> 00:08:09,620 Wait let me try to turn up. 124 00:08:10,110 --> 00:08:10,830 Whoa. 125 00:08:11,700 --> 00:08:14,110 Cause that's that's broadcasting my microphone. 126 00:08:14,330 --> 00:08:19,350 Let me try to set the microphone of this recording to be my iPhone. 127 00:08:19,580 --> 00:08:26,110 And then when I take a picture we should be able to hear it now. 128 00:08:27,290 --> 00:08:28,320 Did you hear that. 129 00:08:28,340 --> 00:08:31,890 That's what we're that's what we just said let's do it again. 130 00:08:32,010 --> 00:08:34,420 All right. 131 00:08:34,700 --> 00:08:38,420 And did you guys hear the camera shutter sound as well that's in there we just couldn't hear it because 132 00:08:38,420 --> 00:08:40,430 I didn't have the sound patched through correctly. 133 00:08:40,430 --> 00:08:45,200 All right let's let's try with something that he doesn't know. 134 00:08:45,420 --> 00:08:47,020 It's so cool. 135 00:08:47,360 --> 00:08:50,760 Let's see maybe I can try it with. 136 00:08:50,960 --> 00:08:52,580 Let's try it with some sunglasses. 137 00:08:52,580 --> 00:08:53,520 Here we go. 138 00:08:54,040 --> 00:08:54,690 Let's see. 139 00:08:57,340 --> 00:08:58,910 I'm not sure why this is. 140 00:08:58,930 --> 00:08:59,920 Please try again. 141 00:08:59,930 --> 00:09:00,370 See 142 00:09:03,250 --> 00:09:06,290 oh oh see. 143 00:09:06,440 --> 00:09:09,290 And one thing to remember guys is this is not an exact science. 144 00:09:09,290 --> 00:09:14,420 It's not absolutely perfect because it's not going to be able to identify every object it's only going 145 00:09:14,420 --> 00:09:17,100 to be able to go off of what it knows and what it understands. 146 00:09:17,150 --> 00:09:21,530 But sometimes you can see what why it made the association it did. 147 00:09:21,530 --> 00:09:23,160 It said this was a jeweler's loop. 148 00:09:23,270 --> 00:09:29,330 And if you think about it a jeweler's loop is a circular device with a circular piece of glass and a 149 00:09:29,330 --> 00:09:33,340 kind of a lens looking thing so it makes sense why it thinks certain things at time. 150 00:09:33,350 --> 00:09:36,780 Let's try this again. 151 00:09:42,350 --> 00:09:43,150 All right cool. 152 00:09:43,160 --> 00:09:46,190 So as you can see it can identify things it's not perfect. 153 00:09:46,190 --> 00:09:51,500 It has its issues but a lot of things that can identify properly which is just so cool. 154 00:09:51,500 --> 00:09:57,280 We have an app that can identify it can speak to us it can do all these amazing things. 155 00:09:57,320 --> 00:09:57,610 All right. 156 00:09:57,620 --> 00:10:01,790 So really cool this this works we can tap it 157 00:10:05,030 --> 00:10:06,680 and it speaks to us which is very cool. 158 00:10:06,680 --> 00:10:12,740 But the issue is right now I can tap on the screen 10 times and it's going to speak 10 times of what 159 00:10:12,740 --> 00:10:14,270 I saw and when I took photos of. 160 00:10:14,270 --> 00:10:20,160 So I think that we should add a little activity spinner on this image to show that it's loading and 161 00:10:20,160 --> 00:10:20,880 it's speaking. 162 00:10:20,900 --> 00:10:26,600 And we should basically disable the tap gesture recognizer while it's speaking. 163 00:10:26,720 --> 00:10:27,230 OK. 164 00:10:27,290 --> 00:10:28,760 It's really easy to set this up. 165 00:10:28,760 --> 00:10:33,410 But first we need to go ahead and add a UI activity indicator. 166 00:10:33,410 --> 00:10:39,080 So go ahead and type UI activity indicator view and of course we're in mind that storyboard we're going 167 00:10:39,080 --> 00:10:43,590 to drag that on and center it right there on our image view. 168 00:10:43,700 --> 00:10:50,690 We're going to set it to be white and we're going to pin it in the exact center of this container which 169 00:10:50,750 --> 00:10:51,460 of course. 170 00:10:51,500 --> 00:10:52,550 Oh you know what. 171 00:10:52,640 --> 00:10:53,970 No that is not what we want. 172 00:10:53,990 --> 00:10:59,930 We want to select the image view then the activity indicator and we want to give them the same horizontal 173 00:10:59,930 --> 00:11:01,510 and vertical center. 174 00:11:01,550 --> 00:11:02,000 OK. 175 00:11:02,180 --> 00:11:03,200 Just like that. 176 00:11:03,500 --> 00:11:07,620 And you know what we're going to actually set this to be hidden from the get go. 177 00:11:07,820 --> 00:11:10,460 So you can actually just do that right in Interface Builder. 178 00:11:10,700 --> 00:11:16,850 We don't need to do that in code or anything but what we do need to do is we need to add an IB action 179 00:11:17,030 --> 00:11:24,160 or rather an outlet so that we can modify this we can show it we can animate it et cetera et cetera. 180 00:11:24,170 --> 00:11:29,690 So in Interface Builder go ahead and open up the assistant editor and if it's not already there go ahead 181 00:11:29,690 --> 00:11:34,950 and click automatic and it should load the proper view controller and that looks good. 182 00:11:35,000 --> 00:11:37,550 When to close those get out of my way. 183 00:11:37,610 --> 00:11:38,150 Perfect. 184 00:11:38,150 --> 00:11:38,440 OK. 185 00:11:38,450 --> 00:11:41,160 So go ahead and right click. 186 00:11:41,720 --> 00:11:48,590 Right click from the activity indicator and go ahead and drag over to your other outlets which are down 187 00:11:48,590 --> 00:11:54,300 here for me and I'm just going to call this the spinner because that's basically what it is is a spinner. 188 00:11:54,530 --> 00:12:00,550 Now go ahead and go back to your code file and just make sure we can get. 189 00:12:00,560 --> 00:12:01,850 We have our spinner. 190 00:12:01,850 --> 00:12:02,780 That's awesome. 191 00:12:03,050 --> 00:12:11,300 And now what we need to do is we need to basically change so that whenever we tap the camera view it's 192 00:12:11,300 --> 00:12:13,530 going to go ahead and show the spinner. 193 00:12:13,790 --> 00:12:20,720 It's going to go ahead and pause out the tap gesture recognizer so that input cannot be sent in anymore. 194 00:12:20,990 --> 00:12:28,390 And then it's basically going to hide and re-enable the tap gesture recognizer as soon as it's done. 195 00:12:28,400 --> 00:12:32,420 And know what we also added this function did finish utterance. 196 00:12:32,420 --> 00:12:35,520 That's where we can re-enable everything which is perfect. 197 00:12:35,540 --> 00:12:43,340 So go ahead and actually up here at the top when we call did tap camera view here's what we're going 198 00:12:43,340 --> 00:12:43,730 to do. 199 00:12:43,730 --> 00:12:51,050 We're going to call self camera view is user interaction and enable set to false because when we tap 200 00:12:51,050 --> 00:12:54,550 it we should disable it from showing anything really. 201 00:12:54,680 --> 00:12:55,800 That is what we're going to do. 202 00:12:55,970 --> 00:13:04,160 So go ahead and type that and yeah we just disable the camera view from being tapped while it is capturing 203 00:13:04,850 --> 00:13:08,180 the photo sending it to our model et cetera et cetera. 204 00:13:08,210 --> 00:13:11,950 So we just set it up so that the user interaction is disabled. 205 00:13:12,020 --> 00:13:16,520 And now we're going to also unhide our spinner and we're going to started animating because when we 206 00:13:16,520 --> 00:13:19,150 tap on the camera view that's basically when everything starts floating. 207 00:13:19,150 --> 00:13:25,790 So go ahead and type self whip's self-taught spinner is hidden because remember we hit it in the interface 208 00:13:25,790 --> 00:13:31,140 builder that's going to be equal to false and then we're going to go ahead and type self that spinner 209 00:13:31,160 --> 00:13:35,330 don't start animating. 210 00:13:35,330 --> 00:13:39,690 That's right because that's going to start it actually doing its spin animation. 211 00:13:40,130 --> 00:13:44,150 OK so cool so our camera views disabled our spinner is animating. 212 00:13:44,150 --> 00:13:49,190 Now we need to think about when we want to re-enable the camera view and hide the spinner. 213 00:13:49,310 --> 00:13:51,290 And that is when it's done speaking. 214 00:13:51,350 --> 00:13:52,010 OK. 215 00:13:52,250 --> 00:13:59,030 So we already added this delegate method did finish utterance and that is used to determine when the 216 00:13:59,090 --> 00:14:01,520 speech synthesizer is finished talking. 217 00:14:01,520 --> 00:14:03,050 So that's super easy. 218 00:14:03,050 --> 00:14:05,900 All we need to do is basically do the opposite of what we just did. 219 00:14:05,900 --> 00:14:11,620 So self camera view is user interaction enabled is true. 220 00:14:11,660 --> 00:14:13,980 Now it can be tapped again. 221 00:14:14,030 --> 00:14:19,160 Let's go ahead and call self-caused spinnerbait is hidden equals true. 222 00:14:19,190 --> 00:14:19,830 OK. 223 00:14:20,570 --> 00:14:21,260 That's very cool. 224 00:14:21,260 --> 00:14:23,300 That's all we need to do is to hide our spinner. 225 00:14:23,540 --> 00:14:25,550 Oh you know what we should also stop it from animating 226 00:14:29,430 --> 00:14:30,450 OK. 227 00:14:30,480 --> 00:14:35,750 So now when it's done speaking it's going to go ahead and re-enable the camera view. 228 00:14:35,820 --> 00:14:38,410 It's going to hide the spinner and stop it from animating. 229 00:14:38,520 --> 00:14:41,010 Let's build and run and let's double check to make sure that works. 230 00:14:41,010 --> 00:14:46,500 This is just the way that we prevent the app from having too much input which could cause crashes it 231 00:14:46,500 --> 00:14:51,750 could cause memory issues and there's really no need to scan 100 things like right at once. 232 00:14:51,750 --> 00:14:57,240 So let's let's tap the screen and you'll hear the camera shutters sound and when I tap on the screen 233 00:14:57,240 --> 00:14:59,670 you shouldn't hear it again until it's done. 234 00:14:59,790 --> 00:15:03,330 We should also see the spin or show up although I see right now that it's not actually hidden. 235 00:15:03,330 --> 00:15:04,430 So we're going to need to fix that. 236 00:15:04,440 --> 00:15:05,380 But let's try it. 237 00:15:07,720 --> 00:15:08,790 Can tapping the screen. 238 00:15:08,790 --> 00:15:10,740 Nothing's happening. 239 00:15:11,180 --> 00:15:14,680 OK it's done it head when I tap it again. 240 00:15:14,870 --> 00:15:18,170 Ok cool. 241 00:15:18,530 --> 00:15:19,040 Very cool. 242 00:15:19,040 --> 00:15:20,010 So that works. 243 00:15:20,010 --> 00:15:26,760 But let's go let's go determine why it's not hidden from the get go. 244 00:15:26,810 --> 00:15:31,830 Maybe I put the wrong thing in the camera view is hidden. 245 00:15:31,850 --> 00:15:36,270 Oh did tap camera view is hidden is supposed to. 246 00:15:36,410 --> 00:15:38,970 Oh wait no it's it's supposed to show when I tap the camera view. 247 00:15:40,290 --> 00:15:41,660 Is hidden it's true. 248 00:15:42,680 --> 00:15:45,870 And let's go to the main story board I did hide that right. 249 00:15:46,920 --> 00:15:49,930 OK yeah it says it's hidden. 250 00:15:50,510 --> 00:15:54,170 Well I guess you know what let's go let's go hide it in code. 251 00:15:54,170 --> 00:15:59,060 Sometimes you can't rely on interface builder so let's go ahead and type spinner that is hidden. 252 00:15:59,060 --> 00:16:00,180 And let's set that to true. 253 00:16:00,200 --> 00:16:01,490 Let's build it again. 254 00:16:01,500 --> 00:16:05,840 Let's make sure that the spinner is actually hidden when we first load the app there's no use in having 255 00:16:05,840 --> 00:16:07,850 a spinner doing nothing. 256 00:16:07,970 --> 00:16:09,590 It's kind of confusing actually. 257 00:16:09,590 --> 00:16:10,310 OK good. 258 00:16:10,310 --> 00:16:10,990 So it's gone. 259 00:16:11,000 --> 00:16:13,420 Let's go ahead and tap the screen. 260 00:16:13,730 --> 00:16:17,210 Let's tap tap tap tap tap tap tap nothing. 261 00:16:18,840 --> 00:16:19,440 Cool. 262 00:16:19,660 --> 00:16:26,080 So when it's done I was able to tap into it again. 263 00:16:27,920 --> 00:16:28,310 OK. 264 00:16:28,360 --> 00:16:30,580 Pretty confident yourself there Siri. 265 00:16:30,580 --> 00:16:36,430 Anyway awesome so we just added some code to make sure that too much input is not getting in to our 266 00:16:36,430 --> 00:16:36,870 app. 267 00:16:37,030 --> 00:16:38,520 But guys this is incredible. 268 00:16:38,530 --> 00:16:44,620 Our app is done we've just built an app using machine learning that uses a pre-trained model to identify 269 00:16:44,620 --> 00:16:45,790 objects. 270 00:16:45,790 --> 00:16:51,190 Show what they are on the screen and speak to us what they are it's pretty amazing if you think about 271 00:16:51,190 --> 00:16:53,140 the technology that this is utilizing. 272 00:16:53,140 --> 00:16:55,830 Thank you guys so much for going through this section of the course. 273 00:16:55,840 --> 00:16:59,700 I hope this is what your appetite for core M-L and all the things it can do. 274 00:16:59,830 --> 00:17:03,160 There are so many ways you could extend this app to make it more amazing. 275 00:17:03,280 --> 00:17:08,980 You could use this as a way to tag and classify photos to make different albums you could use this as 276 00:17:08,980 --> 00:17:11,130 a way to catalog some of your stuff. 277 00:17:11,140 --> 00:17:17,280 I have a remote control I have some sunglasses I have this thing you can use it to catalog your stuff. 278 00:17:17,290 --> 00:17:22,000 There are lots of different ways that you could extend this app to make it more amazing. 279 00:17:22,000 --> 00:17:25,170 Now this is just one core M-L model squeezed net. 280 00:17:25,210 --> 00:17:26,390 The one that we're using. 281 00:17:26,530 --> 00:17:27,370 There are other ones. 282 00:17:27,370 --> 00:17:35,410 There's one a one from one called Places 2 0 5 Google net I think and it's utilized to identify scenes 283 00:17:35,410 --> 00:17:39,700 and places to tell you what kind of a senior at are you in a city or you at the beach or you in the 284 00:17:39,700 --> 00:17:40,600 forest. 285 00:17:40,600 --> 00:17:46,270 That's just another cool type of Corum that you can use the most amazing thing is all of this is happening 286 00:17:46,360 --> 00:17:47,170 on your device. 287 00:17:47,170 --> 00:17:50,460 Locally we don't even need to reach out to an API or a server. 288 00:17:50,530 --> 00:17:52,170 So so cool. 289 00:17:52,420 --> 00:17:54,040 Thank you guys so much great work. 290 00:17:54,040 --> 00:17:56,260 And let's head over to the next section of this course.
