本文介紹了Google Cloud Speech API添加SpeechContext的處理方法，對(duì)大家解決問(wèn)題具有一定的參考價(jià)值，需要的朋友們下面隨著小編來(lái)一起學(xué)習(xí)吧！

問(wèn)題描述

我想在我的應(yīng)用程序中添加一些關(guān)鍵字，這樣API就可以更高效地識(shí)別口語(yǔ)。
例如Im having trouble recognizing the some Italian words that starts with E、(E`Per Me)等?；虻抡Z(yǔ)(呃)。

以下是我的代碼：

public void recognize (int sampleRate) {
    if (mApi == null) {
        Log.w(TAG, "API not ready. Ignoring the request.");
        return;
    }
    // Configure the API
    mRequestObserver = mApi.streamingRecognize(mResponseObserver);
    mRequestObserver.onNext(StreamingRecognizeRequest.newBuilder()
            .setStreamingConfig(StreamingRecognitionConfig.newBuilder()
                    .setConfig(RecognitionConfig.newBuilder()
                            .setLanguageCode(getDefaultLanguageCode())
                            .setEncoding(RecognitionConfig.AudioEncoding.LINEAR16)
                            .setSampleRateHertz(sampleRate)
                            .build())
                    .setInterimResults(true)
                    .setSingleUtterance(true)
                    .build())
            .build());
}

設(shè)置不同大小寫(xiě)的語(yǔ)言：

private String getDefaultLanguageCode() {

    SharedPreferences getLangSharedPrefs = getSharedPreferences("langSelected",0);
    String selectedLanguage = getLangSharedPrefs.getString("langSelected", null);
    switch (selectedLanguage) {
        case "German":
            langaugeCode = "de-DE";
            break;
        case "Italian":
            langaugeCode = "it-IT";
            break;
        case "Spanish" :
            langaugeCode = "es-ES";
            break;
        case "French" :
            langaugeCode = "fr-FR";
            break;
    }
    return langaugeCode;
}

推薦答案

我找到解決方案了：

 public void startRecognizing(int sampleRate) {
    if (mApi == null) {
        Log.w(TAG, "API not ready. Ignoring the request.");
        return;
    }
    // Configure the API
    mRequestObserver = mApi.streamingRecognize(mResponseObserver);
    SpeechContext.Builder speechBuilder = SpeechContext.newBuilder();
    speechBuilder.addPhrases("E per me");
    speechBuilder.addPhrases("E");
    mRequestObserver.onNext(StreamingRecognizeRequest.newBuilder()
            .setStreamingConfig(StreamingRecognitionConfig.newBuilder()
                    .setConfig(RecognitionConfig.newBuilder()
                            .setLanguageCode(getDefaultLanguageCode())
                            .setEncoding(RecognitionConfig.AudioEncoding.LINEAR16)
                            .setSampleRateHertz(sampleRate)
                            .addSpeechContexts(speechBuilder)
                            .build())
                    .setInterimResults(true)
                    .setSingleUtterance(true)
                    .build())
            .build());
}
