PocketSphinx 是一个开源的语音识别引擎,可以在低配置的 Android 设备上运行。以下是在低配置 Android 设备上使用 PocketSphinx 的步骤:
dependencies {
implementation 'edu.cmu.pocketsphinx:pocketsphinx-android:5prealpha'
}
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.INTERNET" />
SpeechRecognizer recognizer = defaultSetup()
.setAcousticModel(new File(modelsDir, "en-us-ptm"))
.setDictionary(new File(modelsDir, "cmudict-en-us.dict"))
.setLanguageModel(new File(modelsDir, "en-us.lm.dmp"))
.getRecognizer();
recognizer.startListening(new RecognizerIntent(), new RecognitionListener() {
@Override
public void onPartialResult(Hypothesis hypothesis) {
String text = hypothesis.getHypstr();
Log.d("PocketSphinx", "Partial result: " + text);
}
@Override
public void onResult(Hypothesis hypothesis) {
String text = hypothesis.getHypstr();
Log.d("PocketSphinx", "Final result: " + text);
}
@Override
public void onBeginningOfSpeech() {
Log.d("PocketSphinx", "Speech started");
}
@Override
public void onEndOfSpeech() {
Log.d("PocketSphinx", "Speech ended");
}
@Override
public void onError(Exception e) {
Log.e("PocketSphinx", "Error: " + e.getMessage());
}
@Override
public void onTimeout() {
Log.d("PocketSphinx", "Timeout");
}
});
@Override
protected void onResume() {
super.onResume();
recognizer.startListening();
}
@Override
protected void onPause() {
super.onPause();
recognizer.stop();
}
通过以上步骤,您可以在低配置 Android 设备上使用 PocketSphinx 进行语音识别。请注意,由于低配置设备的性能限制,识别的准确性可能会有所降低。
