Question

这是我的java代码：

public static void main(String[] args) {

    TextToSpeech textService = new TextToSpeech(IBM_WATSON_USERNAME, IBM_WATSON_PASSWORD);

    //String voice = "en-US_AllisonVoice";
    String text = "This is Just awesome And i am going to experience the effect";
    //String format = "audio/mp3";

    try {
        InputStream in = textService.synthesize(text, Voice.EN_ALLISON, AudioFormat.OGG_VORBIS)
                .execute();
        System.out.println(in.available());

    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

}

当我在eclipse中执行代码时，我得到了：

Dec 12, 2017 3:05:08 PM okhttp3.internal.platform.Platform log
INFO: --> POST https://stream.watsonplatform.net/text-to-speech/api/v1/synthesize?voice=en-US_AllisonVoice&accept=audio/ogg;%20codecs%3Dvorbis http/1.1 (71-byte body)

in.available（）的输出为：0

为什么我没有收到任何音频？根据POST请求，我可以看到我的文本没有被POSTED。我错过了什么？

来自available()的{{1}}方法将始终返回0，因为它取决于InputStream的实现。请参阅InputStream Javadoc。

调用InputStream时得到的InputStream，它是来自synthesize()库的byteStream（）。

您需要从okHttp读取到文件或其他位置。以下是可用于此的代码段：

InputStream

注意：上面的代码段没有任何inputStream = textToSpeech.synthesize(/* parameters*/).execute(); outputStream = new FileOutputStream(new File("audio.ogg")); int read = 0; byte[] bytes = new byte[1024]; while ((read = inputStream.read(bytes)) != -1) { outputStream.write(bytes, 0, read); } System.out.println("Done!");，也没有关闭流。我会把它留给你=）

Watson Text to speech不产生音频输出
