Ios:ios10 and Xcode8 Create Siri features

Prelude:

When IOS 10 comes out, our developers can also use Siri-like features. It uses a speech recognition framework inside Siri to speech the framework to handle Siri. Now, let's take a look at some of the main code. We need a uitextview and a UIButton to show it.

Realize:

• First step: Defining properties

@interfaceViewcontroller () <SFSpeechRecognizerDelegate>@property (Strong, nonatomic) UIButton*Siribtu; //siri button @property (Strong, nonatomic) Uitextview*Siritextview; //Display speech converted to text @property (strong, nonatomic) Sfspeechrecognitiontask*Recognitiontask; //Speech recognition Task @property (Strong, nonatomic) Sfspeechrecognizer*SpeechRecognizer; //Speech recognizer @property (Strong, nonatomic) Sfspeechaudiobufferrecognitionrequest*recognitionrequest; //Identification Request @property (strong, nonatomic) Avaudioengine*Audioengine; //Recording engine @end

• Step two: Make speech recognition detection

- (void) viewdidload {[Super viewdidload];

   //Device identification language is Chinese Nslocale*cale = [[Nslocale alloc]initwithlocaleidentifier:@"ZH-CN"]; Self.speechrecognizer=[[Sfspeechrecognizer Alloc]initwithlocale:cale]; Self.siriBtu.enabled=false;

　//Set proxy _speechrecognizer.Delegate=Self ;

　//Send voice authentication request (first to determine whether the device supports speech recognition function) [Sfspeechrecognizer requestauthorization:^(sfspeechrecognizerauthorizationstatus status) {BOOLisbuttonenabled =false; Switch(status) { Casesfspeechrecognizerauthorizationstatusauthorized:isbuttonenabled=true; NSLog (@"can speech recognition");  Break;  Casesfspeechrecognizerauthorizationstatusdenied:isbuttonenabled=false; NSLog (@"user is denied access to speech recognition");  Break;  Casesfspeechrecognizerauthorizationstatusrestricted:isbuttonenabled=false; NSLog (@"cannot make speech recognition on this device");  Break;  Casesfspeechrecognizerauthorizationstatusnotdetermined:isbuttonenabled=false; NSLog (@"No authorized speech recognition");  Break; default:                 Break; } self.siriBtu.enabled=isbuttonenabled; }];

　　//Create recording engine Self.audioengine=[[Avaudioengine alloc]init];}

• Step three: Click events for the button

-(void ) Microphonetap: (UIButton *if   ([Self.audioengine isrunning]) {[SELF.A        Udioengine stop];        [Self.recognitionrequest Endaudio];        self.siriBtu.enabled  = YES; [Self.siribtu settitle:  @ "  start recording   "     Forstate:uicontrolstatenormal];         else  {[self startrecording]; [Self.siribtu settitle:  @ "  stop recording   "     Forstate:uicontrolstatenormal]; }}

• Fourth step: Start recording voice and convert speech to text

-(void) startrecording{if(self.recognitiontask) {[Self.recognitiontask cancel]; Self.recognitiontask=Nil; } avaudiosession*audiosession =[Avaudiosession sharedinstance]; BOOLAudiobool =[Audiosession Setcategory:avaudiosessioncategoryrecord Error:nil]; BOOLaudiobool1=[Audiosession setmode:avaudiosessionmodemeasurement Error:nil]; BOOLaudiobool2= [audiosession setActive:truewithoptions:avaudiosessionsetactiveoptionnotifyothersondeactivation Error:nil]; if(Audiobool | | audiobool1| |audioBool2) {NSLog (@"can use"); }Else{NSLog (@"This shows that some features do not support"); } self.recognitionrequest=[[Sfspeechaudiobufferrecognitionrequest alloc]init]; Avaudioinputnode*inputnode =Self.audioEngine.inputNode; Sfspeechaudiobufferrecognitionrequest*recognitionrequest; Self.recognitionRequest.shouldReportPartialResults=true;

　　//start to identify task Self.recognitiontask= [Self.speechrecognizer recognitionTaskWithRequest:self.recognitionRequest resulthandler:^ ( Sfspeechrecognitionresult * _nullable result, Nserror *_nullable Error) {        BOOLIsFinal =false; if(Result) {Self.siriTextView.text=[[Result besttranscription] formattedstring]; //Voice to text isfinal=[result isfinal]; }        if(Error | |isfinal)            {[Self.audioengine stop]; [Inputnode Removetaponbus:0]; Self.recognitionrequest=Nil; Self.recognitiontask=Nil; Self.siriBtu.enabled=true;    }    }]; Avaudioformat*recordingformat = [Inputnode outputformatforbus:0]; [Inputnode Installtaponbus:0BufferSize:1024x768Format:recordingformat block:^ (Avaudiopcmbuffer * _nonnull buffer, Avaudiotime *_nonnull when)    {[Self.recognitionrequest appendaudiopcmbuffer:buffer];        }];    [Self.audioengine prepare]; BOOLAudioenginebool =[Self.audioengine Startandreturnerror:nil]; NSLog (@"%d", Audioenginebool); Self.siriTextView.text=@"I'm Xiaoice! Siri ice, you say I listen";}

• Fifth step: Implement this proxy method, the implementation of Siri voice function

-(void) SpeechRecognizer: (Sfspeechrecognizer *) SpeechRecognizer Availabilitydidchange: (BOOL) available{    if(available) {        true;    } Else {        false;    }}
