我正在尝试使用SFSpeechRecognizer，但我没有办法测试我是否正确实现它，并且由于它是一个相对较新的类，我找不到示例代码（我不知道 swift）。我是否犯了任何不可原谅的错误/遗漏了什么？

[SFSpeechRecognizer requestAuthorization:^(SFSpeechRecognizerAuthorizationStatus status){
    if (status == SFSpeechRecognizerAuthorizationStatusAuthorized) {
        SFSpeechRecognizer* recognizer = [[SFSpeechRecognizer alloc] init];
        recognizer.delegate = self;
        SFSpeechAudioBufferRecognitionRequest* request = [[SFSpeechAudioBufferRecognitionRequest alloc] init];
        request.contextualStrings = @[@"data", @"bank", @"databank"];

        SFSpeechRecognitionTask* task = [recognizer recognitionTaskWithRequest:request resultHandler:^(SFSpeechRecognitionResult* result, NSError* error){
            SFTranscription* transcript = result.bestTranscription;
            NSLog(@"%@", transcript);
        }];
    }
}];

我也在尝试，但这段代码对我有用，毕竟 SFSpeechRecognizer 和 SFSpeechAudioBufferRecognitionRequest 不一样，所以我认为（尚未测试）你必须要求不同的权限（你之前是否要求过权限？使用麦克风和语音识别？）。好的，这是代码：

//Available over iOS 10, only for maximum 1 minute, need internet connection; can be sourced from an audio recorded file or over the microphone

    NSLocale *local =[[NSLocale alloc] initWithLocaleIdentifier:@"es-MX"];
        speechRecognizer = [[SFSpeechRecognizer alloc] initWithLocale:local];
        NSString *soundFilePath = [myDir stringByAppendingPathComponent:@"/sound.m4a"];
        NSURL *url = [[NSURL alloc] initFileURLWithPath:soundFilePath];
        if(!speechRecognizer.isAvailable)
            NSLog(@"speechRecognizer is not available, maybe it has no internet connection");
        SFSpeechURLRecognitionRequest *urlRequest = [[SFSpeechURLRecognitionRequest alloc] initWithURL:url];
        urlRequest.shouldReportPartialResults = YES; // YES if animate writting
        [speechRecognizer recognitionTaskWithRequest: urlRequest resultHandler:  ^(SFSpeechRecognitionResult * _Nullable result, NSError * _Nullable error)
        {
    NSString *transcriptText = result.bestTranscription.formattedString;
            if(!error)
            {
        NSLog(@"transcriptText");
            }
        }];
