谷歌云语音到文本长音频响应

• 问答

我正在尝试将音频转换为文本，但是得到的结果是

LongRunningRecognizeResponse { results: [] }

这是我的职责，

    const audio = {
    uri: `gs://${BUCKET}/${fileName}`,};

const request = {
    config: {
        encoding: 'LINEAR16',sampleRateHertz: 16000,languagecode: 'en-US',},audio: audio,};

client.longRunningRecognize(request)
    .then(responses => {
        const [operation,initialApiResponse] = responses;

        operation.on('complete',(result,metadata,finalApiResponse) => {
            console.log('complete',result) // LongRunningRecognizeResponse { results: [] }
        });

        operation.on('progress',(metadata,apiResponse) => {
            console.log('progress',apiResponse)
        });

        operation.on('error',err => {
            throw (err);
        });
    })

const transcribeLong = async (url,channels) => {
    const nameExtract = url.split('/');
    const fileName = nameExtract[nameExtract.length - 1];
    let localfile;
    try {
        localfile = await download(url);
        fs.writeFileSync(fileName,localfile);
        await storage.bucket(BUCKET).upload(fileName);
        const audio = {
            uri: `gs://${BUCKET}/${fileName}`,};
        const request = {
            config: {
                languageCode: `en-US`,alternativeLanguageCodes: [`es-MX`,`en-US`],encoding: 'LINEAR16',sampleRateHertz: 8000,audioChannelCount: channels || 2,//changed from 2
                enableSeparateRecognitionPerChannel: true,},audio,};
        const [operation] = await client.longRunningRecognize(request);
        const [response] = await operation.promise();
        return response
    } catch (error) {
        console.error(error.toString());
    }
};

问题在请求中以错误的渠道作为参数。
