使用node js将语音保存为本地文本

Question

我正在尝试复制https://github.com/googleapis/nodejs-speech/blob/master/samples/recognize.js.当我在本地运行它时没有错误。但在这里，我很困惑在哪里可以看到创建的结果。有没有一种方法可以将结果写入文件？

这是代码。

const record = require('node-record-lpcm16');
// Imports the Google Cloud client library
const speech = require('@google-cloud/speech');
// Creates a client
const client = new speech.SpeechClient();
/**
* TODO(developer): Uncomment the following lines before running the sample.
*/
const encoding = 'LINEAR16';
const sampleRateHertz = 16000;
const languageCode = 'en-US';
const request = {
config: {
encoding: encoding,
sampleRateHertz: sampleRateHertz,
languageCode: languageCode,
},
interimResults: false, // If you want interim results, set this to true
};
// Create a recognize stream
const recognizeStream = client
.streamingRecognize(request)
.on('error', console.error)
.on('data', data =>
process.stdout.write(
data.results[0] && data.results[0].alternatives[0] ?
`Transcription: ${data.results[0].alternatives[0].transcript}n` :
`nnReached transcription time limit, press Ctrl+Cn`
)
);
// Start recording and send the microphone input to the Speech API
record
.start({
sampleRateHertz: sampleRateHertz,
threshold: 0,
// Other options, see https://www.npmjs.com/package/node-record-lpcm16#options
verbose: false,
recordProgram: 'sox', // Try also "arecord" or "sox"
silence: '10.0',
})
.on('error', console.error)
.pipe(recognizeStream);
console.log('Listening, press Ctrl+C to stop.');

这很令人困惑：(.请让我知道我如何才能做到这一点。

感谢

Answer 1

它在"数据"中。请查看代码并查看控制台如何记录数据。

示例：

client
.recognize(request)
.then(data => {
const response = data[0];
const transcription = response.results
.map(result => result.alternatives[0].transcript)
.join('n');
console.log(`Transcription: `, transcription);
})
