连续语音识别 UWP

Question

我正在使用 UWP 创建一个智能镜子应用程序，我尝试将该应用程序与连续语音识别集成，以便用户可以使用语音来控制它。但是 Bing Speech REST API 不支持连续语音识别，所以我还能用什么吗？如果有源码就更好了

Answer 1

Windows.Media.SpeechRecognition支持连续识别。 Microsoft Github for UWP 在他们的 Speech recognition and synthesis sample or check out the Microsoft Docs for Windows.Media.SpeechRecognition

中有一个这样的例子

Answer 2

我从这段代码中找到了一些思路，希望对你也有帮助。

    public sealed partial class MainPage : Page
{      public MainPage()
    {
        this.InitializeComponent();
    }

    //連続音声認識のためのオブジェクト
    private SpeechRecognizer contSpeechRecognizer;
    private CoreDispatcher dispatcher;


    protected async override void OnNavigatedTo(NavigationEventArgs e)
    {
        //ハックグラウンドスレッドからUIスレッドを呼び出すためのDispatcher
        dispatcher = CoreWindow.GetForCurrentThread().Dispatcher;

        //初期化
        contSpeechRecognizer =
            new Windows.Media.SpeechRecognition.SpeechRecognizer();
        await contSpeechRecognizer.CompileConstraintsAsync();

        //認識中の処理定義
        contSpeechRecognizer.HypothesisGenerated +=
            ContSpeechRecognizer_HypothesisGenerated;
        contSpeechRecognizer.ContinuousRecognitionSession.ResultGenerated +=
            ContinuousRecognitionSession_ResultGenerated;


        // 音声入力ないままタイムアウト(20秒位)した場合の処理
        contSpeechRecognizer.ContinuousRecognitionSession.Completed += ContinuousRecognitionSession_Completed;

        //認識開始
        await contSpeechRecognizer.ContinuousRecognitionSession.StartAsync();
    }

    private async void ContinuousRecognitionSession_Completed(SpeechContinuousRecognitionSession sender, SpeechContinuousRecognitionCompletedEventArgs args)
    {
        await dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
        {
            textBlock1.Text = "Timeout.";
        });

        // 音声を再度待ち受け
        await contSpeechRecognizer.ContinuousRecognitionSession.StartAsync();
    }

    private async void ContSpeechRecognizer_HypothesisGenerated(
        SpeechRecognizer sender, SpeechRecognitionHypothesisGeneratedEventArgs args)
    {
        //認識途中に画面表示
        await dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
        {
            textBlock1.Text = args.Hypothesis.Text;
        });
    }

    private async void ContinuousRecognitionSession_ResultGenerated(
        SpeechContinuousRecognitionSession sender, SpeechContinuousRecognitionResultGeneratedEventArgs args)
    {
        //認識完了後に画面に表示
        await dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
        {
            textBlock1.Text = "Waiting ...";
            output.Text += args.Result.Text + "。\n";
        });
    }
}
