00:00:00,200 --> 00:00:01,010

Hi everyone.



2

00:00:01,020 --> 00:00:02,590

So now in this tutorial.



3

00:00:02,640 --> 00:00:07,260

Let's actually go ahead and let's go inside this activity underline minute example here.



4

00:00:07,500 --> 00:00:09,460

So here you can see this takes you right.



5

00:00:09,480 --> 00:00:13,410

Just click on it and you can see that the idea is to the right you.



6

00:00:13,470 --> 00:00:16,240

So now let's go to our main activity class here.



7

00:00:16,440 --> 00:00:22,350

And inside this class let's declare an object or a variable of type the text you here sort of set in



8

00:00:22,350 --> 00:00:24,630

here takes the view text view.



9

00:00:24,630 --> 00:00:27,210

Now let's give a name to our valuable here.



10

00:00:27,270 --> 00:00:30,850

So as I step in here fix the underlying value.



11

00:00:30,900 --> 00:00:31,340

Right.



12

00:00:31,350 --> 00:00:33,480

So this is the name of my variable semicolon.



13

00:00:33,510 --> 00:00:35,630

So here I just declared my variable.



14

00:00:35,820 --> 00:00:39,170

Now let's go inside is uncreate Smurfette here.



15

00:00:39,480 --> 00:00:44,850

And after this line of code here that we actually call this set content view method I'm going to initialize



16

00:00:45,000 --> 00:00:49,100

this variable so I can say Pique's the underlying value assignment operator.



17

00:00:49,110 --> 00:00:57,870

So now we need to cast this object to a fixed view object find view by id r that ID that takes the value



18

00:00:58,160 --> 00:00:58,880

semicolon.



19

00:00:58,910 --> 00:00:59,630

That's it.



20

00:00:59,640 --> 00:01:00,040

Right.



21

00:01:00,060 --> 00:01:07,620

So here let's create a method inside the main activity class in order to allow the user to actually



22

00:01:07,620 --> 00:01:10,280

use the speech recognition framework.



23

00:01:10,530 --> 00:01:11,760

So let's scroll down here.



24

00:01:11,790 --> 00:01:15,000

And after the end curly brace of this uncreate method.



25

00:01:15,030 --> 00:01:20,620

And before the end in curly brace of this main activity class I can say private's OK.



26

00:01:20,620 --> 00:01:24,060

Void and the name of the Smurfette here is going to be.



27

00:01:24,090 --> 00:01:28,750

Listen listen to the users voice through the user's voice.



28

00:01:28,830 --> 00:01:33,360

And here just put a bit of practice this year and then open and close this method by using the curly



29

00:01:33,360 --> 00:01:34,620

braces.



30

00:01:34,620 --> 00:01:36,910

So now I can say so inside the Smurfette.



31

00:01:36,930 --> 00:01:42,870

Let's Create of idea of pipe intent so we can say intent and the name of this rally is going to be voice



32

00:01:42,930 --> 00:01:45,080

intent or its intent.



33

00:01:45,120 --> 00:01:47,200

Assignment operator new.



34

00:01:47,670 --> 00:01:50,220

So I'm going to create a new object of intent right.



35

00:01:50,270 --> 00:01:54,260

So new intent and instead the practice is just typing here.



36

00:01:54,300 --> 00:01:59,240

Recognize their intent that action recognize speech.



37

00:01:59,240 --> 00:01:59,950

So semicolon.



38

00:01:59,970 --> 00:02:06,570

So you're going to create a new intent in order to allow the user to actually talk to his or her phone



39

00:02:06,840 --> 00:02:10,110

or keep using this action recognized speech intent.



40

00:02:10,110 --> 00:02:17,250

So after this line of code we are going to send some data to this to this action recognize speech intent.



41

00:02:17,250 --> 00:02:21,170

So for example I can say voice intent voice intent.



42

00:02:21,180 --> 00:02:22,910

That puts extra.



43

00:02:22,980 --> 00:02:25,450

So this put extra needs to argument.



44

00:02:25,470 --> 00:02:31,460

The first argument is going to be the key and the second argument is going to be the actual date up



45

00:02:31,710 --> 00:02:34,030

that we want to see into this intent.



46

00:02:34,140 --> 00:02:37,460

So the first one is key so it is going to be recognizer intent.



47

00:02:37,530 --> 00:02:44,220

That extra that extra prompt underline prompt or case is the key comma.



48

00:02:44,400 --> 00:02:48,130

So we're going to prompt the user to actually talk to the phone.



49

00:02:48,330 --> 00:02:54,180

So that's why the key is called Extra prompt and the second argument is going to be a string value.



50

00:02:54,240 --> 00:02:57,840

And here I can't say touch to me.



51

00:02:58,000 --> 00:02:59,150

Talk to me.



52

00:02:59,260 --> 00:03:01,140

Exclamation mark semicolon.



53

00:03:01,150 --> 00:03:03,930

So again just typing here voice intent.



54

00:03:04,210 --> 00:03:10,130

That puts extra and for the first argument we need to specify the key.



55

00:03:10,180 --> 00:03:12,740

You can see that the first argument must be of type string.



56

00:03:12,750 --> 00:03:15,220

Right because all these versions of this method.



57

00:03:15,210 --> 00:03:18,580

Here the first argument which is the key is always of types 3.



58

00:03:18,670 --> 00:03:27,670

So recognizer intent that language just type typing here language and here extra language model is this



59

00:03:27,670 --> 00:03:27,870

one.



60

00:03:27,880 --> 00:03:28,560

This is the key.



61

00:03:28,690 --> 00:03:34,680

So here we want to specify that the user can actually talk in any language that he or she wants.



62

00:03:34,690 --> 00:03:42,010

So that's why the key is called extra language model and the value is going to be recognizer intent.



63

00:03:42,190 --> 00:03:48,780

That language model that language model free for that's it.



64

00:03:48,820 --> 00:03:49,640

Semi-colon.



65

00:03:49,780 --> 00:03:51,740

So let's create a new line here.



66

00:03:51,760 --> 00:03:56,810

So here I am saying that the user can't speak in any language that he or she wants.



67

00:03:56,830 --> 00:04:00,170

Language model free for this is the key extra language model.



68

00:04:00,190 --> 00:04:06,370

So again after this line of code I can say and here finally we need to specify the maximum results that



69

00:04:06,370 --> 00:04:08,530

we want to get from the user's speech.



70

00:04:08,530 --> 00:04:18,220

So I can't say we seem to end that puts extra is recognize or intent that extra underline Max results



71

00:04:19,130 --> 00:04:22,650

comma and the value is going to be.



72

00:04:22,660 --> 00:04:25,620

For example I want to get 10 actually 10 results.



73

00:04:25,630 --> 00:04:26,360

Semicolon.



74

00:04:26,410 --> 00:04:27,870

That's it right.



75

00:04:27,880 --> 00:04:31,950

And finally we need to call this if it's thought activity for result.



76

00:04:31,990 --> 00:04:34,160

We are not going to start activity here.



77

00:04:34,180 --> 00:04:39,580

We are going to start activity for results because if you want to actually get the data from the voiced



78

00:04:39,760 --> 00:04:45,490

intent so just call this the start activity for result and then when it passed the intent if she's going



79

00:04:45,490 --> 00:04:50,440

to be voice Internet karma and the request quote is is going to be the request code that you actually



80

00:04:50,440 --> 00:04:56,410

created inside the main activity class this one speech request so let's pass this value here.



81

00:04:56,500 --> 00:04:57,700

Speech request.



82

00:04:57,730 --> 00:04:58,350

That's it.



83

00:04:58,570 --> 00:05:01,840

So now this is our listen to the user's voice method right.



84

00:05:01,900 --> 00:05:04,660

So where do we actually call this method from.



85

00:05:04,790 --> 00:05:11,830

We are going to call this method from our uncreate method and after the inside if statement that we



86

00:05:11,830 --> 00:05:18,730

are 100 percent sure that the user user's device actually supports speech recognition right.



87

00:05:18,850 --> 00:05:24,460

So inside this statement We are saying that TOSed that may test your device does not support speech



88

00:05:24,460 --> 00:05:25,240

recognition.



89

00:05:25,240 --> 00:05:28,630

So here I can call this Meffert listen to the users voice.



90

00:05:28,630 --> 00:05:31,010

Right now I can scroll down here.



91

00:05:31,270 --> 00:05:32,520

So this is my faith.



92

00:05:32,590 --> 00:05:35,600

And here inside is main activity class.



93

00:05:35,740 --> 00:05:42,790

I am going to call this method of activity results suggest typing here an activity result so he had



94

00:05:42,790 --> 00:05:47,360

this is the method that we need to override here in order to actually get the data from the voice.



95

00:05:47,380 --> 00:05:49,510

Intent here inside the Smurfette.



96

00:05:49,660 --> 00:05:55,360

First we need to create an if statement so if request code so I'm going to refer to the first argument



97

00:05:55,690 --> 00:06:03,430

that we get from the Smurfit If request code is equal to the request code that we actually sent to this



98

00:06:03,430 --> 00:06:03,970

intent.



99

00:06:04,020 --> 00:06:08,740

OK this Meffert voice intent so if you sent this request code here for this instance right.



100

00:06:08,740 --> 00:06:16,750

So I am actually saying if request code is equal to that speech request here and excuse me and result



101

00:06:16,750 --> 00:06:21,130

code so if you have another argument here result quote is equal to result.



102

00:06:21,140 --> 00:06:24,200

Ok then I can open and close this if statement.



103

00:06:24,280 --> 00:06:32,110

And inside this statement I can be 100 percent sure that we get this data here that we get the data



104

00:06:32,140 --> 00:06:34,940

from the actually voice intent here.



105

00:06:35,080 --> 00:06:36,720

This statement is really important.



106

00:06:36,730 --> 00:06:41,890

That's why we create our request called a speaking request here so that later when we want to get the



107

00:06:41,890 --> 00:06:48,400

data from the voice intent we can actually to use this request not hear this speech request code in



108

00:06:48,400 --> 00:06:55,590

order to be sure that the data is coming from the specific intent that we want to get the data from.



109

00:06:55,700 --> 00:06:58,910

OK so in this if statement I can't say so.



110

00:06:58,990 --> 00:07:05,820

Now let's create an array list of string values so I can't say I least and instead the angle brackets.



111

00:07:05,830 --> 00:07:14,460

I can say strange and the name of my aerialist is going to be voice words voice for its assignment operator.



112

00:07:14,470 --> 00:07:22,270

So here I can refer to this argument which is of that intent data that gets strange aerialist extra



113

00:07:22,930 --> 00:07:24,850

get string Aurelia's extra.



114

00:07:25,060 --> 00:07:32,850

And here as an argument I can't pass this value recognizer intent that extra resolves extra underline



115

00:07:32,860 --> 00:07:35,200

results right semicolon.



116

00:07:35,230 --> 00:07:38,790

So let me create a new line here so that they can see what's going on here.



117

00:07:38,800 --> 00:07:46,030

So you are going to get the warts that the user has actually said and we are going to assign those words



118

00:07:46,120 --> 00:07:51,280

into this at least here which is of type string and are a list of string values.



119

00:07:51,310 --> 00:07:57,740

So after this line of code we can also get a decimal value from this ancient.



120

00:07:57,740 --> 00:08:04,190

So what is that this decimal value is the symbol value is going to be the preciseness of divorce that



121

00:08:04,190 --> 00:08:06,550

we are going to get from the user's voice.



122

00:08:06,610 --> 00:08:07,000

Right.



123

00:08:07,010 --> 00:08:09,150

Which is called comfort levels.



124

00:08:09,380 --> 00:08:16,220

So let's create an array of floats values float and put a pair of brackets here and here the name of



125

00:08:16,220 --> 00:08:21,050

this array is going to be confit levels assignment operator.



126

00:08:21,140 --> 00:08:27,920

And here again if you are going to refer to the state is of the intent that get float and a extra dot



127

00:08:27,950 --> 00:08:31,100

get float get float.



128

00:08:31,310 --> 00:08:39,440

Add a extra that argument past this value recognizer intent that extra confidence scores semi-colon.



129

00:08:39,440 --> 00:08:43,430

So here let me create on your line here so that you can see what's going on here.



130

00:08:43,580 --> 00:08:47,800

And now it's time to output the results to the screen.



131

00:08:47,840 --> 00:08:53,630

So now let's first like let's actually create a variable of that integer index assignment operator zero



132

00:08:53,690 --> 00:08:54,510

semicolon.



133

00:08:54,530 --> 00:08:58,040

Let's create a for in loop here instead of Frances just typing here.



134

00:08:58,040 --> 00:08:58,820

Streambed.



135

00:08:59,310 --> 00:09:04,720

And here I can't say a voice word or use that word use the word colon.



136

00:09:05,100 --> 00:09:12,530

And here we are going to iterate over each value each string value that we have inside this latest voice



137

00:09:12,530 --> 00:09:14,680

words voice words.



138

00:09:14,690 --> 00:09:21,300

So this for English here is going to be executed for each string value that we have inside is released.



139

00:09:21,320 --> 00:09:23,810

So insert this for loop here.



140

00:09:24,110 --> 00:09:25,930

Let's create an if statement.



141

00:09:25,970 --> 00:09:29,800

So if and here I'm going to refer to this at a comfort level.



142

00:09:29,990 --> 00:09:40,050

If comfort levels is not equal to null an index is less than I'm going to now I'm going to the entity



143

00:09:40,070 --> 00:09:42,860

is actually at a coffee levels that lenth.



144

00:09:42,910 --> 00:09:47,590

So only in that case we are going to actually execute the codes inside the if statement.



145

00:09:47,650 --> 00:09:53,380

First we are going to specify that if this array is not equal to all and if the index that we have here



146

00:09:53,680 --> 00:09:59,050

is actually less than the length the number of elements that we have inside this country it was only



147

00:09:59,050 --> 00:10:05,650

in this case only if these two conditions are true we can be actually 100 percent sure that we've got



148

00:10:05,650 --> 00:10:11,340

some words some words from the user that we can actually output them to the screen.



149

00:10:11,470 --> 00:10:17,640

So inside this if statement I can say TXI the underlying value it said text.



150

00:10:17,650 --> 00:10:19,240

So here just refer to this.



151

00:10:19,240 --> 00:10:26,400

Use the word plus two two coats and here just put a dash sheer space plus.



152

00:10:26,410 --> 00:10:31,680

And we are going to also out with the value of the comfort level so the comfort level is going to be.



153

00:10:31,780 --> 00:10:36,120

So let's refer to discomfit levels Aure and put a pair of brackets your index.



154

00:10:36,130 --> 00:10:36,580

So that's it.



155

00:10:36,580 --> 00:10:39,090

In this way you are going to get to use a word.



156

00:10:39,280 --> 00:10:45,280

And we also going we are going to actually get a comfort level of that specific word here from this



157

00:10:45,290 --> 00:10:45,920

arii.



158

00:10:46,210 --> 00:10:51,670

OK so now let's run the application and let's see what happens.



159

00:10:51,670 --> 00:10:53,840

So choose one of these devices and then click on OK.



160

00:10:53,860 --> 00:10:56,820

So now you can see that our emulator is running.



161

00:10:56,860 --> 00:10:59,050

And here it says talk to me.



162

00:10:59,050 --> 00:10:59,930

Right.



163

00:11:00,010 --> 00:11:04,700

But as you can see here it is actually an emulator out here.



164

00:11:04,970 --> 00:11:11,860

And we cannot use this feature here inside our emulator unit to test this app on your actual Android



165

00:11:11,860 --> 00:11:12,300

device.



166

00:11:12,310 --> 00:11:16,390

So I'm going to test it now I'm going to test this app on my Android device and I'm going to see whether



167

00:11:16,420 --> 00:11:18,030

this app is going to work or not.



168

00:11:18,070 --> 00:11:24,310

So I actually tested the app on my Android device and it didn't work because there is a bug here inside



169

00:11:24,370 --> 00:11:26,270

our unactivated results Meffert.



170

00:11:26,330 --> 00:11:29,070

So inside the Smurfette look at this piece of code here.



171

00:11:29,080 --> 00:11:31,920

This condition here is that Apprentice's of this statement.



172

00:11:31,930 --> 00:11:36,220

Here we are saying if we Quest's code is equal to speak request.



173

00:11:36,220 --> 00:11:37,500

So here it is true.



174

00:11:37,640 --> 00:11:40,380

And request again here.



175

00:11:40,450 --> 00:11:46,470

We must refer to this result code and I mistakenly referred to this request code instead.



176

00:11:46,480 --> 00:11:49,670

So here I should actually delete this value and I should actually type it here.



177

00:11:49,700 --> 00:11:50,920

Result code.



178

00:11:51,040 --> 00:11:52,570

Ok this is very important.



179

00:11:52,570 --> 00:11:55,920

You may actually later for example do this mistake.



180

00:11:56,140 --> 00:12:01,690

So make sure to avoid these kinds of mistakes and make sure to always check your statements for any



181

00:12:01,690 --> 00:12:03,780

kinds of mistakes like this one.



182

00:12:04,030 --> 00:12:11,470

So if the score is equal to speak request and result code here is equal to result.



183

00:12:11,470 --> 00:12:17,720

OK so this condition is for actually checking that if anything if actually for example getting the data



184

00:12:17,720 --> 00:12:24,770

up from the voice intent was actually executed this process was actually executed normally.



185

00:12:24,820 --> 00:12:30,680

So this piece of what he had this condition is necessary in order to access the data of that voice intent.



186

00:12:30,730 --> 00:12:31,280

Right.



187

00:12:31,600 --> 00:12:35,920

So now let me test the app on my Android device again here.



188

00:12:35,920 --> 00:12:39,090

So I just want to select this device here and I just need to click on OK.



189

00:12:39,160 --> 00:12:44,550

So here I actually recorded my android screen in order to show you how this app works.



190

00:12:44,550 --> 00:12:52,230

So let me play this video so here I actually said hello and now you can see that the halo is outputted



191

00:12:52,240 --> 00:12:52,690

here.



192

00:12:52,840 --> 00:12:54,440

Inside our takes you.



193

00:12:54,730 --> 00:12:55,360

So that's it.



194

00:12:55,390 --> 00:12:59,500

If you have any questions please post the discussion in the course and then I'll do my best to answer



195

00:12:59,530 --> 00:13:00,670

all of your questions.
