1 00:00:07,250 --> 00:00:12,790 Guys this is Caleb with slopes and in this video we're going to set up an instance of a speech synthesizer 2 00:00:13,000 --> 00:00:17,060 to speak what we see in our images it's going to be really cool. 3 00:00:17,080 --> 00:00:22,450 And when I initially thought of this idea I thought of it as a way to be kind of like an assistive technology 4 00:00:22,870 --> 00:00:24,860 perhaps to those who are vision impaired. 5 00:00:25,000 --> 00:00:29,950 If they if they can't see what is in front of them they could use our app to scan things and it could 6 00:00:29,950 --> 00:00:35,200 speak to them so they can hear what they're seeing so kind of like they can see with their ears supercool 7 00:00:35,740 --> 00:00:39,540 and actually to use Avie speech synthesizer is not very difficult. 8 00:00:39,790 --> 00:00:42,700 So I just want to show you how to use it and how I use it in this app. 9 00:00:42,700 --> 00:00:49,540 So pull open that X code project and let's go ahead and let's begin by actually creating an instance 10 00:00:49,630 --> 00:00:51,820 of A-V speech synthesizer. 11 00:00:51,850 --> 00:01:01,520 So go ahead and type var speech synthesizer and that's going to be of type Avie speech synthesizer can 12 00:01:01,570 --> 00:01:03,010 instantiate it. 13 00:01:03,340 --> 00:01:04,570 And that's that. 14 00:01:04,570 --> 00:01:09,250 Now if you look deeply inside of this you'll notice that this comes from A-V foundation. 15 00:01:09,250 --> 00:01:13,910 So we've already integrated the foundation to capture our photo. 16 00:01:14,020 --> 00:01:20,060 But the a part of A-V stands for audio and that's where our A-V speech synthesizer will come into play. 17 00:01:20,220 --> 00:01:20,770 OK. 18 00:01:21,220 --> 00:01:28,570 Now what we do need to do for this to work is we need to set the speech synthesisers delegate to be 19 00:01:28,930 --> 00:01:30,150 this view controller. 20 00:01:30,190 --> 00:01:35,310 So go ahead and type speech synthesizer delegate and that equals self. 21 00:01:35,320 --> 00:01:41,800 Now if we try to build and run this there is an error cannot assign value of type camera AVC to A-V 22 00:01:41,800 --> 00:01:44,090 speech synthesizer delegate. 23 00:01:44,260 --> 00:01:51,630 Now to fix that we're going to create an extension of A-V speech synthesizer delegate K that's going 24 00:01:51,630 --> 00:01:55,680 to give us the ability to call some important delegate methods that we need. 25 00:01:55,690 --> 00:02:00,430 So go ahead and type extension CAMRA AVC and we're going to do. 26 00:02:00,440 --> 00:02:03,510 Avies speech synthesizer delegate. 27 00:02:03,920 --> 00:02:04,340 OK. 28 00:02:04,390 --> 00:02:09,670 And the function we're going to call is called did finish utterance and we'll talk about that in a second. 29 00:02:09,940 --> 00:02:17,840 So just go ahead and add that function and code to finish utterance We'll come back to that in a second. 30 00:02:17,980 --> 00:02:24,360 But for now if we go back up to view whereas that view did appear you can see that error went away because 31 00:02:24,370 --> 00:02:27,640 now we are conforming to speech synthesizer delegate. 32 00:02:27,640 --> 00:02:29,050 That's all we need. 33 00:02:29,050 --> 00:02:37,900 So in order to actually speak something we need to be able to create a speech utterance to get an avi 34 00:02:37,900 --> 00:02:40,030 speech utterance to actually speak. 35 00:02:40,030 --> 00:02:41,770 We need to pass it a string. 36 00:02:41,890 --> 00:02:47,470 So we're going to create a function that basically allows us to pass a string into an avi speech utterance 37 00:02:47,500 --> 00:02:49,990 and then use our synthesizer to speak it. 38 00:02:49,990 --> 00:02:59,840 So go ahead and type phunk synthesize speech speech from string and we're going to use an internal parameter 39 00:02:59,840 --> 00:03:01,740 they're called string. 40 00:03:02,090 --> 00:03:04,440 Of course of type string. 41 00:03:04,850 --> 00:03:10,520 And basically what we're going to do is we'll create an instance of Avie speech utterance we'll pass 42 00:03:10,520 --> 00:03:15,130 it the string and then we will ask our synthesizer to speak the utterance. 43 00:03:15,140 --> 00:03:21,420 So go ahead and type let speech utterance equals Avies speech utterance. 44 00:03:21,710 --> 00:03:25,310 And we're going to pass a string K and that's what it's going to speak. 45 00:03:25,310 --> 00:03:28,870 Now of course this is the string we're passing in. 46 00:03:28,910 --> 00:03:34,280 So go ahead and type string and it can be that lowercase string from the internal parameter. 47 00:03:34,750 --> 00:03:42,060 OK so then now that we have that utterance we can call our synthesizer K speech synthesizer speak. 48 00:03:42,080 --> 00:03:50,750 And you'll notice it asks for an example of A-V speech utterance and we have that speech whoops speech 49 00:03:51,170 --> 00:03:52,380 utterance. 50 00:03:52,370 --> 00:03:53,570 OK that's what we need to pass it. 51 00:03:53,580 --> 00:03:59,740 Now this function for any string we pass in it will speak it. 52 00:03:59,810 --> 00:04:05,310 That's the cool thing of Avies speech synthesizer any string we pass in it's going to speak for us. 53 00:04:05,420 --> 00:04:13,670 So we need to determine when we should speak this and that is basically when we classify our results. 54 00:04:13,700 --> 00:04:18,860 So when we pull through all of our classifications if it comes to something that it has no idea what 55 00:04:18,860 --> 00:04:22,540 it is if it's not sure we should speak that OK. 56 00:04:22,880 --> 00:04:27,380 Now what we're going to do is we're actually going to take this string and I'm going to go ahead and 57 00:04:27,380 --> 00:04:29,320 copy it and delete it. 58 00:04:29,480 --> 00:04:35,400 And we're going to call this let unknown object message. 59 00:04:35,780 --> 00:04:37,570 And that's what we're going to use here. 60 00:04:37,790 --> 00:04:39,990 Unknown object message. 61 00:04:40,100 --> 00:04:46,280 We're going to also use that in our synthesized speech function so go ahead and call synthesized speech 62 00:04:46,280 --> 00:04:50,070 from string and we're gonna give it our unknown object message. 63 00:04:50,090 --> 00:04:54,740 Now whenever we find something that we don't know what it is it's going to say I'm not sure what this 64 00:04:54,740 --> 00:04:55,010 is. 65 00:04:55,010 --> 00:04:56,320 Please try again. 66 00:04:56,360 --> 00:04:57,180 Very cool. 67 00:04:57,500 --> 00:05:07,250 But we need to also create a string that's going to classify our object and give a level of confidence. 68 00:05:07,340 --> 00:05:13,270 So to do that I'm going to go ahead and I'm going to actually create some variables for this as well 69 00:05:13,280 --> 00:05:23,850 so I'm going to cut this and just create var identification and let's go ahead and do var confidence. 70 00:05:23,960 --> 00:05:30,720 And we're going to actually take our confidence value here as well and let's go ahead and cut that out. 71 00:05:30,740 --> 00:05:31,920 Let's put it here. 72 00:05:32,060 --> 00:05:32,660 Cut that out. 73 00:05:32,660 --> 00:05:33,830 Confidence. 74 00:05:33,830 --> 00:05:34,490 All right cool. 75 00:05:34,610 --> 00:05:37,520 So we're going to pass in the confidence that we just created. 76 00:05:37,520 --> 00:05:41,490 We're going to give this the identification as a string. 77 00:05:41,690 --> 00:05:43,250 And so that looks good. 78 00:05:43,700 --> 00:05:46,640 OK let's go ahead and make sure those little warnings go away. 79 00:05:47,110 --> 00:05:47,720 Oh OK. 80 00:05:47,780 --> 00:05:48,940 They were never mutated. 81 00:05:49,010 --> 00:05:50,740 Let's just create them in two constants. 82 00:05:50,750 --> 00:05:52,270 Good call X code. 83 00:05:52,460 --> 00:05:54,280 Always looking out for me. 84 00:05:54,290 --> 00:05:54,740 Very cool. 85 00:05:54,740 --> 00:05:55,000 OK. 86 00:05:55,010 --> 00:05:55,850 So that's good. 87 00:05:56,120 --> 00:06:02,840 But now we need to speak what it is that we saw so let's call synthesized speech and this string what 88 00:06:02,840 --> 00:06:10,460 we're going to do is we're going to compile both of these into a nice long sentence that makes sense 89 00:06:10,460 --> 00:06:12,160 that feels like natural language. 90 00:06:12,170 --> 00:06:16,560 So let's call this complete sentence. 91 00:06:17,180 --> 00:06:22,780 And we're going to basically say this looks like a. 92 00:06:23,480 --> 00:06:27,050 And we're going to pass in the identifier or sorry the identification. 93 00:06:27,050 --> 00:06:28,720 This looks like a fish. 94 00:06:28,730 --> 00:06:32,780 This looks like a remote and I'm 95 00:06:35,480 --> 00:06:38,090 and here's where we pass in our confidence. 96 00:06:38,540 --> 00:06:38,890 OK. 97 00:06:38,910 --> 00:06:41,610 I'm blank per cent sure. 98 00:06:41,630 --> 00:06:48,030 So for an example this could be this looks like a remote control and I'm 98 percent sure. 99 00:06:48,170 --> 00:06:49,240 Pretty cool. 100 00:06:49,240 --> 00:06:54,700 Now we're going to synthesize that complete sentence so that it speaks that outloud and. 101 00:06:54,940 --> 00:06:55,630 Yeah. 102 00:06:55,730 --> 00:06:56,830 So this should work. 103 00:06:56,840 --> 00:06:59,310 This should synthesize our speech. 104 00:06:59,780 --> 00:07:05,000 If we go inside A-V speech synthesizer if you look inside of it you can see it has a delegate it has 105 00:07:05,000 --> 00:07:10,490 all kinds of booleans to check to see whether or not it's speaking if it's pause it has some functions 106 00:07:10,490 --> 00:07:11,660 to speak. 107 00:07:11,660 --> 00:07:15,220 And I should have shown you that earlier but I didn't. 108 00:07:15,290 --> 00:07:20,790 You can look inside here and you can see all of the cool things that A-V speech synthesizer and Avies 109 00:07:20,790 --> 00:07:22,090 speech utterance can do. 110 00:07:22,100 --> 00:07:24,410 You can even change the voice which is kind of cool. 111 00:07:24,410 --> 00:07:27,950 There's a system default but you could turn it into a different voice. 112 00:07:27,950 --> 00:07:29,990 And we can play around with that later. 113 00:07:29,990 --> 00:07:33,720 But for now let's go ahead and build and run this let's see if it works. 114 00:07:37,820 --> 00:07:40,180 OK let's pull open quick time here. 115 00:07:40,410 --> 00:07:43,030 Time using two is what I'm using to record my screen. 116 00:07:43,040 --> 00:07:47,900 If you don't know you can go in quick time and you can actually choose your iPhone as an input camera 117 00:07:47,900 --> 00:07:48,910 which is very cool. 118 00:07:49,160 --> 00:07:53,770 So anyway let's go ahead and let's tap on the screen k. 119 00:07:53,960 --> 00:08:01,510 So it looks like it's showing the K looks like it's showing everything but it doesn't appear that it's 120 00:08:01,510 --> 00:08:04,340 speaking. 121 00:08:04,570 --> 00:08:08,140 Let's see oh you know what I bet. 122 00:08:08,200 --> 00:08:09,590 Wait let me try to turn up. 123 00:08:10,020 --> 00:08:10,770 Whoa. 124 00:08:11,670 --> 00:08:14,270 Because that's that's broadcasting my microphone. 125 00:08:14,280 --> 00:08:19,120 Let me try to set the microphone of this recording to be my iPhone. 126 00:08:19,530 --> 00:08:26,080 And then when I take a picture we should be able to hear it now. 127 00:08:27,240 --> 00:08:28,270 Did you hear that. 128 00:08:28,290 --> 00:08:31,750 That's what we that's what we just said let's do it again. 129 00:08:31,910 --> 00:08:34,410 All right. 130 00:08:34,630 --> 00:08:38,370 And did you guys hear the camera shutter sound as well that's in there we just couldn't hear it because 131 00:08:38,370 --> 00:08:40,380 I didn't have the sound patch through correctly. 132 00:08:40,380 --> 00:08:45,400 All right let's let's try with something that he doesn't know. 133 00:08:45,680 --> 00:08:46,970 It's so cool. 134 00:08:47,310 --> 00:08:50,680 Let's see maybe I can try it with. 135 00:08:50,920 --> 00:08:52,530 Let's try it with some sunglasses. 136 00:08:52,530 --> 00:08:53,920 Here we go. 137 00:08:53,990 --> 00:08:54,640 Let's see. 138 00:08:57,290 --> 00:08:58,860 I'm not sure what this is. 139 00:08:58,880 --> 00:09:00,590 Please try again and see. 140 00:09:03,970 --> 00:09:05,870 Oh. 141 00:09:06,380 --> 00:09:11,900 And one thing to remember guys is this is not an exact science it's not absolutely perfect because it's 142 00:09:11,900 --> 00:09:13,930 not going to be able to identify every object. 143 00:09:13,930 --> 00:09:17,030 It's only going to be able to go off of what it knows and what it understands. 144 00:09:17,090 --> 00:09:21,470 But sometimes you can see what it is why it made the association it did. 145 00:09:21,470 --> 00:09:23,090 It said this was a jeweler's loop. 146 00:09:23,210 --> 00:09:29,270 And if you think about it a jeweler's loop is a circular device with a circular piece of glass and a 147 00:09:29,270 --> 00:09:33,290 kind of a lens looking thing so it makes sense why it thinks certain things at time. 148 00:09:33,290 --> 00:09:36,780 Let's try this again. 149 00:09:42,300 --> 00:09:43,060 All right cool. 150 00:09:43,110 --> 00:09:49,080 So as you can see it can identify things it's not perfect it has its issues but a lot of things that 151 00:09:49,080 --> 00:09:51,450 can identify properly which is just so cool. 152 00:09:51,450 --> 00:09:57,230 We have an app that can identify it can speak to us it can do all these amazing things. 153 00:09:57,270 --> 00:09:57,560 All right. 154 00:09:57,560 --> 00:10:03,870 So really cool this this works we can tap it. 155 00:10:04,980 --> 00:10:06,630 And it speaks to us which is very cool. 156 00:10:06,630 --> 00:10:12,690 But the issue is right now I can tap on the screen 10 times and it's going to speak 10 times of what 157 00:10:12,690 --> 00:10:14,210 I saw and what I took photos of. 158 00:10:14,210 --> 00:10:20,100 So I think that we should add a little activity spinner on this image to show that it's loading and 159 00:10:20,100 --> 00:10:20,820 it's speaking. 160 00:10:20,820 --> 00:10:26,540 And we should basically disable the tap gesture recognizer while it's speaking. 161 00:10:26,670 --> 00:10:27,180 OK. 162 00:10:27,240 --> 00:10:28,700 It's really easy to set this up. 163 00:10:28,710 --> 00:10:33,240 But first we need to go ahead and add a UI activity indicator. 164 00:10:33,360 --> 00:10:39,000 So go ahead and type UI activity indicator view and of course we're in mind that storyboard we're going 165 00:10:39,000 --> 00:10:43,540 to drag that on and center it right there on our UI image view. 166 00:10:43,650 --> 00:10:50,640 We're going to set it to be white and we're going to pin it in the exact center of this container which 167 00:10:50,700 --> 00:10:52,480 of course oh you know what. 168 00:10:52,560 --> 00:10:53,920 No that is not what we want. 169 00:10:53,940 --> 00:10:59,850 We want to select the image view then the activity indicator and we want to give them the same horizontal 170 00:10:59,850 --> 00:11:01,420 and vertical center. 171 00:11:01,460 --> 00:11:01,950 OK. 172 00:11:02,130 --> 00:11:03,140 Just like that. 173 00:11:03,420 --> 00:11:07,570 And you know what we're going to actually set this to be hidden from the get go. 174 00:11:07,770 --> 00:11:10,590 So you can actually just do that right in Interface Builder. 175 00:11:10,650 --> 00:11:16,800 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 176 00:11:16,980 --> 00:11:24,110 or rather an outlet so that we can modify this we can show it we can animate it et cetera et cetera. 177 00:11:24,120 --> 00:11:29,640 So in Interface Builder go ahead and open up the assistant editor and if it's not already there go ahead 178 00:11:29,640 --> 00:11:34,860 and click automatic and it should load the proper view controller and that looks good. 179 00:11:34,930 --> 00:11:37,560 When I close those get out of my way. 180 00:11:37,560 --> 00:11:38,100 Perfect. 181 00:11:38,100 --> 00:11:38,360 OK. 182 00:11:38,370 --> 00:11:41,250 So go ahead and right click. 183 00:11:41,670 --> 00:11:48,540 Right click from the activity indicator and go ahead and drag over to your other outlets which are down 184 00:11:48,540 --> 00:11:54,250 here for me and I'm just going to call this the spinner because that's basically what it is is a spinner. 185 00:11:54,480 --> 00:12:00,500 Now go ahead and go back to your code file and just make sure we can get. 186 00:12:00,510 --> 00:12:01,630 We have our spinner. 187 00:12:01,800 --> 00:12:02,970 That's awesome. 188 00:12:03,000 --> 00:12:11,490 And now we need to do is we need to basically change so that whenever we tap the camera view it's going 189 00:12:11,490 --> 00:12:13,740 to go ahead and show the spinner. 190 00:12:13,740 --> 00:12:20,650 It's going to go ahead and pause out the tap gesture recognizer so that input cannot be sent in anymore. 191 00:12:20,910 --> 00:12:28,400 And then it's basically going to hide and re-enable the tap gesture recognizer as soon as it's done. 192 00:12:28,390 --> 00:12:32,300 And we also added this function did finish utterance. 193 00:12:32,370 --> 00:12:35,470 That's where we can re-enable everything which is perfect. 194 00:12:35,490 --> 00:12:43,240 So go ahead and actually up here at the top when we call did tap camera view here's what we're going 195 00:12:43,250 --> 00:12:43,670 to do. 196 00:12:43,680 --> 00:12:51,000 We're going to call self camera view is user interaction and enable set to false because when we tap 197 00:12:51,000 --> 00:12:54,630 it we should disable it from showing anything really. 198 00:12:54,630 --> 00:12:55,740 That is what we're going to do. 199 00:12:55,920 --> 00:13:04,110 So go ahead and type that and yeah we just disable the camera view from being tapped while it is capturing 200 00:13:04,800 --> 00:13:08,130 the photo sending it to our model et cetera et cetera. 201 00:13:08,160 --> 00:13:11,900 So we just set it up so that the user interaction is disabled. 202 00:13:11,970 --> 00:13:16,470 And now we're going to also unhide our spinner and we're going to started animating because when we 203 00:13:16,470 --> 00:13:19,080 tap on the camera view that's basically when everything starts loading. 204 00:13:19,080 --> 00:13:25,740 So go ahead and type self whip's self-taught spinner is hidden because remember we hit it in the interface 205 00:13:25,740 --> 00:13:26,590 builder. 206 00:13:26,850 --> 00:13:28,450 That's going to be equal to false. 207 00:13:28,620 --> 00:13:35,280 And then we're going to go ahead and type self that spinner don't start animating. 208 00:13:35,280 --> 00:13:39,620 That's right because that's going to start at actually doing its spin animation. 209 00:13:40,060 --> 00:13:43,890 OK so cool so our camera views disabled our spinner is animating. 210 00:13:44,100 --> 00:13:49,950 Now we need to think about when we want to re-enable the camera view and hide the spinner and that is 211 00:13:49,950 --> 00:13:51,230 when it's done speaking. 212 00:13:51,300 --> 00:13:51,960 OK. 213 00:13:52,200 --> 00:13:59,010 So we already added this delegate method did finish utterance and that is used to determine when the 214 00:13:59,040 --> 00:14:01,470 speech synthesizer is finished talking. 215 00:14:01,470 --> 00:14:03,000 So that's super easy. 216 00:14:03,000 --> 00:14:05,850 All we need to do is basically do the opposite of what we just did. 217 00:14:05,850 --> 00:14:11,550 So self camera view is user interaction enabled is true. 218 00:14:11,610 --> 00:14:13,520 Now it can be tapped again. 219 00:14:13,950 --> 00:14:19,960 Let's go ahead and call self-caused spinner is hidden equals true OK. 220 00:14:20,510 --> 00:14:21,200 That's very cool. 221 00:14:21,200 --> 00:14:23,260 That's all we need to do is to hide our spinner. 222 00:14:23,480 --> 00:14:25,520 Oh you know what we should also stop it from animating 223 00:14:29,350 --> 00:14:30,390 OK. 224 00:14:30,430 --> 00:14:35,690 So now when it's done speaking it's going to go ahead and re-enable the camera view. 225 00:14:35,770 --> 00:14:40,050 It's going to hide the spinner and stop it from animating let's build and run and let's doublecheck 226 00:14:40,150 --> 00:14:40,960 to make sure that works. 227 00:14:40,960 --> 00:14:46,450 This is just the way that we prevent the app from having too much input which could cause crashes that 228 00:14:46,450 --> 00:14:51,700 could cause memory issues and there's really no need to scan 100 things like right at once. 229 00:14:51,700 --> 00:14:57,190 So let's let's tap the screen and you'll hear the camera shutter sound and when I tap on the screen 230 00:14:57,190 --> 00:14:59,740 you shouldn't hear it again until it's done. 231 00:14:59,740 --> 00:15:03,280 We should also see the spin or show up although I see right now that it's not actually hidden. 232 00:15:03,280 --> 00:15:04,380 So we're going to need to fix that. 233 00:15:04,390 --> 00:15:08,760 But let's try it again tapping the screen. 234 00:15:08,760 --> 00:15:10,680 Nothing's happening. 235 00:15:11,100 --> 00:15:12,370 OK it's done it head. 236 00:15:12,390 --> 00:15:14,150 When I tap it again. 237 00:15:14,850 --> 00:15:18,100 Ok cool. 238 00:15:18,480 --> 00:15:18,990 Very cool. 239 00:15:18,990 --> 00:15:19,950 So that works. 240 00:15:19,970 --> 00:15:26,710 But let's go let's go determine why it's not hidden from the get go. 241 00:15:26,760 --> 00:15:31,750 Maybe I put the wrong thing in the camera view is hidden. 242 00:15:31,780 --> 00:15:36,220 Oh did tap camera view is hidden is supposed to. 243 00:15:36,360 --> 00:15:38,890 Oh wait no it's supposed to show when I tap the camera view. 244 00:15:40,240 --> 00:15:41,600 Is hidden it's true. 245 00:15:42,600 --> 00:15:45,810 And let's go to the main story board I did hide that right. 246 00:15:46,840 --> 00:15:47,200 OK. 247 00:15:47,250 --> 00:15:49,880 Yeah it says it's hidden. 248 00:15:50,460 --> 00:15:54,030 Well I guess you know what let's go let's go hide it in code. 249 00:15:54,120 --> 00:15:58,840 Sometimes you can't rely on Interface Builder So let's go ahead and type spinner that is hidden. 250 00:15:59,010 --> 00:16:00,130 And let's set that to true. 251 00:16:00,150 --> 00:16:01,330 Let's build it again. 252 00:16:01,440 --> 00:16:05,790 Let's make sure that the spinner is actually hidden when we first load the app there's no use in having 253 00:16:05,790 --> 00:16:07,800 a spinner doing nothing. 254 00:16:07,920 --> 00:16:09,540 It's kind of confusing actually. 255 00:16:09,540 --> 00:16:10,260 OK good. 256 00:16:10,260 --> 00:16:10,920 So it's gone. 257 00:16:10,920 --> 00:16:13,420 Let's go ahead and tap the screen. 258 00:16:13,680 --> 00:16:17,510 Let's tap tap tap tap tap tap tap nothing. 259 00:16:18,800 --> 00:16:19,390 Cool. 260 00:16:19,610 --> 00:16:26,230 So when it's done I was able to tap into it again. 261 00:16:27,850 --> 00:16:28,260 OK. 262 00:16:28,310 --> 00:16:30,410 Pretty confident yourself there Siri. 263 00:16:30,500 --> 00:16:36,380 Anyway awesome so we just added some code to make sure that too much input is not getting in to our 264 00:16:36,380 --> 00:16:36,810 app. 265 00:16:36,980 --> 00:16:38,470 But guys this is incredible. 266 00:16:38,480 --> 00:16:39,320 Our app is done. 267 00:16:39,320 --> 00:16:45,510 We've just built an app using machine learning that uses a pre-trained model to identify objects. 268 00:16:45,740 --> 00:16:51,110 Show what they are on the screen and speak to us what they are it's pretty amazing if you think about 269 00:16:51,110 --> 00:16:53,090 the technology that this is utilizing. 270 00:16:53,090 --> 00:16:55,760 Thank you guys so much for going through this section of the course. 271 00:16:55,760 --> 00:16:59,640 I hope this is what your appetite for core M-L and all the things it can do. 272 00:16:59,780 --> 00:17:03,030 There are so many ways you could extend this app to make it more amazing. 273 00:17:03,230 --> 00:17:08,930 You could use this as a way to tag and classify photos to make different albums you could use this as 274 00:17:08,930 --> 00:17:11,090 a way to catalog some of your stuff. 275 00:17:11,090 --> 00:17:17,230 I have a remote control I have some sunglasses I have this thing you can use it to catalog your stuff. 276 00:17:17,240 --> 00:17:21,950 There are lots of different ways that you could extend this app to make it more amazing. 277 00:17:21,950 --> 00:17:25,130 Now this is just one core M-L model squeezed net. 278 00:17:25,160 --> 00:17:26,340 The one that we're using. 279 00:17:26,480 --> 00:17:27,320 There are other ones. 280 00:17:27,320 --> 00:17:35,360 There's one a one from one called Places 2 0 5 Google net I think and it's utilized to identify scenes 281 00:17:35,360 --> 00:17:39,460 and places to tell you what kind of a senior at are you in a city or are you at the beach or are you 282 00:17:39,470 --> 00:17:40,550 in the forest. 283 00:17:40,550 --> 00:17:46,220 That's just another cool type of Corum that you can use the most amazing thing is all of this is happening 284 00:17:46,310 --> 00:17:47,090 on your device. 285 00:17:47,090 --> 00:17:50,410 Locally we don't even need to reach out to an API or a server. 286 00:17:50,480 --> 00:17:52,120 So so cool. 287 00:17:52,370 --> 00:17:53,990 Thank you guys so much great work. 288 00:17:53,990 --> 00:17:56,210 And let's head over to the next section of this course.
