ios 10 出来之后,我们开发者也可以使用类似siri的功能。。让我们来看看怎么使用吧,其实他是使用siri里面的一个语音识别框架speech framework。 让我们来看看 一些 主要的代码吧。 我们需要一个 uitextview 和 uibutton 就 能体现了。

第一步:定义属性

@interface viewcontroller () <sfspeechrecognizerdelegate>
@property (strong, nonatomic) uibutton *siribtu;
@property (strong, nonatomic) uitextview *siritextview;
@property (strong, nonatomic) sfspeechrecognitiontask *recognitiontask;
@property (strong, nonatomic)sfspeechrecognizer *speechrecognizer;
@property (strong, nonatomic) sfspeechaudiobufferrecognitionrequest *recognitionrequest;
@property (strong, nonatomic)avaudioengine *audioengine;
@end

第二步:进行语音识别检测

- (void)viewdidload {
[super viewdidload];
nslocale *cale = [[nslocale alloc]initwithlocaleidentifier:@"zh-cn"];
self.speechrecognizer = [[sfspeechrecognizer alloc]initwithlocale:cale];
self.siribtu.enabled = false;
_speechrecognizer.delegate = self;
[sfspeechrecognizer requestauthorization:^(sfspeechrecognizerauthorizationstatus status) {
bool isbuttonenabled = false;
switch (status) {
case sfspeechrecognizerauthorizationstatusauthorized:
isbuttonenabled = true;
nslog(@"可以语音识别");
break;
case sfspeechrecognizerauthorizationstatusdenied:
isbuttonenabled = false;
nslog(@"用户被拒绝访问语音识别");
break;
case sfspeechrecognizerauthorizationstatusrestricted:
isbuttonenabled = false;
nslog(@"不能在该设备上进行语音识别");
break;
case sfspeechrecognizerauthorizationstatusnotdetermined:
isbuttonenabled = false;
nslog(@"没有授权语音识别");
break;
default:
break;
}
self.siribtu.enabled = isbuttonenabled;
}];
self.audioengine = [[avaudioengine alloc]init];
}

第三步:按钮的点击事件

- (void)microphonetap:(uibutton *)sender {
if ([self.audioengine isrunning]) {
[self.audioengine stop];
[self.recognitionrequest endaudio];
self.siribtu.enabled = yes;
[self.siribtu settitle:@"开始录制" forstate:uicontrolstatenormal];
}else{
[self startrecording];
[self.siribtu settitle:@"停止录制" forstate:uicontrolstatenormal];
}}

第四步 :开始录制语音,以及将语音转为文字

-(void)startrecording{
if (self.recognitiontask) {
[self.recognitiontask cancel];
self.recognitiontask = nil;
}
avaudiosession *audiosession = [avaudiosession sharedinstance];
bool audiobool = [audiosession setcategory:avaudiosessioncategoryrecord error:nil];
bool audiobool1= [audiosession setmode:avaudiosessionmodemeasurement error:nil];
bool audiobool2= [audiosession setactive:true withoptions:avaudiosessionsetactiveoptionnotifyothersondeactivation error:nil];
if (audiobool || audiobool1|| audiobool2) {
nslog(@"可以使用");
}else{
nslog(@"这里说明有的功能不支持");
}
self.recognitionrequest = [[sfspeechaudiobufferrecognitionrequest alloc]init];
avaudioinputnode *inputnode = self.audioengine.inputnode;
sfspeechaudiobufferrecognitionrequest *recognitionrequest;
self.recognitionrequest.shouldreportpartialresults = true;
self.recognitiontask = [self.speechrecognizer recognitiontaskwithrequest:self.recognitionrequest resulthandler:^(sfspeechrecognitionresult * _nullable result, nserror * _nullable error) {
bool isfinal = false;
if (result) {
self.siritextview.text = [[result besttranscription] formattedstring];
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:0 buffersize:1024 format:recordingformat block:^(avaudiopcmbuffer * _nonnull buffer, avaudiotime * _nonnull when) {
[self.recognitionrequest appendaudiopcmbuffer:buffer];
}];
[self.audioengine prepare];
bool audioenginebool = [self.audioengine startandreturnerror:nil];
nslog(@"%d",audioenginebool);
self.siritextview.text = @"我是小冰!????siri 冰,你说我听";
}

最后一个代理方法:

-(void)speechrecognizer:(sfspeechrecognizer *)speechrecognizer availabilitydidchange:(bool)available{
if(available){
self.siribtu.enabled = true;
}else{
self.siribtu.enabled = false;
}
}

这样我们 就可以实现siri的功能了。

总结
