我通过在其中集成IBM Speech-To-Text服务来构建一个android应用程序,在那里我首先录制音频并将其保存到设备中,然后传递进行转换,但是传递音频时,我收到“无法进行错误提示”转码数据流音频/音频->音频/ x-float-array”,我也尝试提供不同格式的音频,但每种格式都出现相同的错误。尽管音频可以正确保存并且可以使用音乐播放器收听。所以,请帮助我摆脱此错误。
在这里,我首先使用MediaRecorder录制音频,然后将其保存到设备中,然后发送以进行对话,但出现错误,我尝试使用每种可能的音频格式
fileName = getExternalCacheDir().getAbsolutePath() + "/" + "examples.wav";
try {
RecognizeOptions recognizeOptions = new RecognizeOptions.Builder()
.audio(new FileInputStream(fileName))
.contentType("audio/wav")
.model("en-US_BroadbandModel")
.build();
BaseRecognizeCallback baseRecognizeCallback =
new BaseRecognizeCallback() {
@Override
public void onTranscription
(SpeechRecognitionResults speechRecognitionResults) {
System.out.println(speechRecognitionResults);
}
@Override
public void onConnected() {
}
@Override
public void onError(Exception e) {
Log.i("Error", e.getMessage());
enableMicButton();
}
@Override
public void onDisconnected() {
enableMicButton();
}
@Override
public void onInactivityTimeout(RuntimeException runtimeException) {
}
@Override
public void onListening() {
}
@Override
public void onTranscriptionComplete() {
}
};
speechToText.recognizeUsingWebSocket(recognizeOptions,
baseRecognizeCallback);
} catch (FileNotFoundException e) {
e.printStackTrace();
}

如果您使用的是watson-developer-cloud Java SDK,以下示例将传递正确的HTTPMediaType
FileInputStream audio = new FileInputStream("src/test/resources/speech_to_text/sample1.wav");
RecognizeOptions options =
new RecognizeOptions.Builder()
.audio(audio)
.interimResults(true)
.contentType(HttpMediaType.AUDIO_WAV)
.build();
service.recognizeUsingWebSocket(
options,
new BaseRecognizeCallback() {
@Override
public void onTranscription(SpeechRecognitionResults speechResults) {
System.out.println(speechResults);
}
@Override
public void onDisconnected() {
lock.countDown();
}
});
