Watson 语音转文本中没有时间戳

Question

我正在使用 Watson-Developer-Cloud 模块，并附上示例：https://www.npmjs.com/package/watson-developer-cloud#speech-to-text

很遗憾，我的所有选项似乎都不起作用：

timestamps: true, profanity_filter: false, word_confidence:true

我是否在正确的地方传递它们？

var watson = require('watson-developer-cloud');
var fs = require('fs');

var speech_to_text = watson.speech_to_text({
  url: "https://stream.watsonplatform.net/speech-to-text/api",
  username: 'xxxxx',
  password: 'xxxxx',
  version: 'v1'
});


fs.createReadStream('./resources/speech.wav')
  .pipe(speech_to_text.createRecognizeStream({ content_type: 'audio/l16; rate=44100', timestamps: true, profanity_filter: false, word_confidence:true }))
  .pipe(fs.createWriteStream('./transcription2.txt'));

我正在取回成绩单，但我想要时间戳和置信度分数。这是我返回的示例：

“五个电话就可以度过愉快的 **** 周”

如您所见，仍然没有时间戳、没有置信度分数和脏话被过滤掉。

我会查看识别流事件以更好地控制输出，例如：

// Create the stream.
var recognizeStream = speech_to_text.createRecognizeStream(params);

// Pipe in the audio.
fs.createReadStream('audio-file.wav').pipe(recognizeStream);

// Pipe out the transcription to a file.
recognizeStream.pipe(fs.createWriteStream('transcription.txt'));

// Get strings instead of buffers from 'data' events.
recognizeStream.setEncoding('utf8');

// Listen for events.
recognizeStream.on('data', function(event) { onEvent('Data:', event); });
recognizeStream.on('results', function(event) { onEvent('Results:', event); });
recognizeStream.on('error', function(event) { onEvent('Error:', event); });
recognizeStream.on('close-connection', function(event) { onEvent('Close:', event); });

// Displays events on the console.
function onEvent(name, event) {
    console.log(name, JSON.stringify(event, null, 2));
};

API documentation 也有一个例子。
