[英]How to Set Sample Rate on Text to Speech - Android
在我的文本到語音的輸出中,我需要將采樣率設置為大約32000赫茲,Pitch - 1和SpeechRate - 0.2(我已經做過)。 但我無法設置采樣率。
tts = new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() {
@Override
public void onInit(int status) {
if(status != TextToSpeech.ERROR) {
tts.setLanguage(Locale.US);
tts.setSpeechRate((float) 0.2);
tts.setPitch((float) 1);
}
}
}, TextToSpeech.Engine.KEY_FEATURE_NETWORK_SYNTHESIS);
我使用AudioTrack來設置采樣率,但是花了很多時間,因為我必須首先使用TTS synthesizeToFile然后在AudioTrack中播放它。
HashMap<String, String> myHasRead = new HashMap<String, String>();
myHasRead.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, outPutS);
String StorePath = Environment.getExternalStorageDirectory().getAbsolutePath();
File myF = new File(StorePath+"/tempAudio.wav");
try {
myF.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
tts.setOnUtteranceProgressListener(new TtsUtteranceListener());
tts.synthesizeToFile("Bla Bla bla",myHasRead, StorePath+"/tempAudio.wav");
....
private class TtsUtteranceListener extends UtteranceProgressListener {
@Override
public void onStart(String utteranceId) {
}
@Override
public void onDone(String utteranceId) {
playWav();
}
@Override
public void onError(String utteranceId) {
}
}
public void playWav(){
int minBufferSize = AudioTrack.getMinBufferSize(32000, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT);
int bufferSize = 512;
AudioTrack at = new AudioTrack(AudioManager.STREAM_MUSIC, 32000, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT, minBufferSize, AudioTrack.MODE_STREAM);
String filepath = Environment.getExternalStorageDirectory().getAbsolutePath();
int i = 0;
byte[] s = new byte[bufferSize];
try {
FileInputStream fin = new FileInputStream(filepath + "/tempAudio.wav");
DataInputStream dis = new DataInputStream(fin);
at.play();
while((i = dis.read(s, 0, bufferSize)) > -1){
at.write(s, 0, i);
}
at.stop();
at.release();
dis.close();
fin.close();
} catch (FileNotFoundException e) {
// TODO
e.printStackTrace();
} catch (IOException e) {
// TODO
e.printStackTrace();
}
}
有任何方法可以將采樣率直接設置為TTS,如tts.setSampleRate(32000);
或者從TTS獲取Stream到AudioTrack,如DataInputStream dis = new DataInputStream(tts.speak("bla bla bla").getDataInputStream);
。 簡而言之,我需要Chipmunk的Android文本到語音,但沒有在AudioTrack中使用synthesizeToFile或直接流TTS語音數據而不保存TTS的輸出。
您無法直接設置TTS采樣率:
我在一個項目中做了類似的事情(Dint使用TTS)
這可能對你有幫助,
用不同的語音類型播放錄音: -
waveSampling = 90000; (花栗鼠)
waveSampling = 24200; (“慢動作”)
waveSampling = 30000;(“BANE”)/蝙蝠俠角色
waveSampling = 18000;(鬼)
waveSampling = 70000;(蜜蜂)
waveSampling = 60000;(女性)
waveSampling = 37000; (正常)
void playRecord() throws IOException {
int minBufferSize = AudioTrack.getMinBufferSize(8000, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT);
int bufferSize = 512;
at = new AudioTrack(AudioManager.STREAM_MUSIC, waveSampling, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT, minBufferSize, AudioTrack.MODE_STREAM);
String filepath = Environment.getExternalStorageDirectory().getAbsolutePath();
int i = 0;
byte[] s = new byte[bufferSize];
try {
FileInputStream fin = new FileInputStream(Environment.getExternalStorageDirectory().getAbsolutePath()+"/Voice Changer/temp/"+filename+".wav");
DataInputStream dis = new DataInputStream(fin);
at.play();
while((i = dis.read(s, 0, bufferSize)) > -1){
at.write(s, 0, i);
}
at.stop();
at.release();
dis.close();
fin.close();
openmenu();
} catch (FileNotFoundException e) {
// TODO
e.printStackTrace();
} catch (IOException e) {
// TODO
e.printStackTrace();
}
}
要保存音頻: -
public void save() throws IOException {
Random r = new Random();
final int i1 = r.nextInt(80 - 65) + 65;
File tempfile2=new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/Voice Changer/temp/"+i1+filename+".wav");
savedfile=Environment.getExternalStorageDirectory().getAbsolutePath()+"/Voice Changer/"+"VOICE CHANGER"+i1+filename+".mp3";
Toast.makeText(this, "File Saved", Toast.LENGTH_SHORT).show();
rawToWave(tempfile,tempfile2);
File wavFile = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/Voice Changer/temp/"+i1+filename+".wav");
IConvertCallback callback = new IConvertCallback() {
@Override
public void onSuccess(File convertedFile) {
File newfile=new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/Voice Changer/"+"VOICE CHANGER"+i1+filename+".mp3");
File savedmp3=new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/Voice Changer/temp/"+i1+filename+".mp3");
Toast.makeText(MainActivity.this, "SUCCESS: " + newfile.getPath(), Toast.LENGTH_LONG).show();
try {
copyit(savedmp3,newfile);
} catch (IOException e) {
e.printStackTrace();
}
}
@Override
public void onFailure(Exception error) {
Toast.makeText(MainActivity.this, "ERROR: " + error.getMessage(), Toast.LENGTH_LONG).show();
}
};
Toast.makeText(this, "Converting audio file...", Toast.LENGTH_SHORT).show();
AndroidAudioConverter.with(this)
.setFile(wavFile)
.setFormat(cafe.adriel.androidaudioconverter.model.AudioFormat.MP3)
.setCallback(callback)
.convert();
}
輸出將是.mp3文件。 如果您想快速輸出,可以使用.wav格式。
