在使用文本到语音之前停止语音识别 [英] Stopping speech recognition before using text to speech
本文介绍了在使用文本到语音之前停止语音识别的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我正在实施一个使用语音识别和文本到语音的对话应用程序.我注意到,一旦启动识别器,它就会尝试识别任何声音,包括文本到语音的结果.
I am implementing a dialogue application using speech recognition and text to speech. I noticed that once the recognizer is started it tries to recognition any sound including the result of the text to speech.
我尝试了下面的代码来阻止它收听 TTS,但我得到了这个异常:
I tried the code below to prevent it to listen to the TTS but I get this exception:
E/JavaBinder(29640): *** Uncaught remote exception! (Exceptions are not yet supported across processes.)
E/JavaBinder(29640): java.lang.RuntimeException: SpeechRecognizer should be used only from the application's main thread

E/SpannableStringBuilder(29640): SPAN_EXCLUSIVE_EXCLUSIVE spans cannot have a zero length
E/SpannableStringBuilder(29640): SPAN_EXCLUSIVE_EXCLUSIVE spans cannot have a zero length
代码 -
UtteranceProgressListener ttsProgressListener = new UtteranceProgressListener(){
@Override
public void onDone(String arg0) {
// TODO Auto-generated method stub
recognizer.startListening(intent);
}
@Override
public void onError(String arg0) {
// TODO Auto-generated method stub
}
@Override
public void onStart(String utteranceId) {
// TODO Auto-generated method stub
recognizer.stopListening();
}
};
你能帮我调试一下吗?
推荐答案
试试这个->
@Override
public void onStart(String utteranceId) {
// TODO Auto-generated method stub
SpeechActivity.this.runOnUiThread(new Runnable() {
@Override
public void run() {
recognizer.stopListening();
}
});
}
