I have created app for speech to text converter. react frontend and nodejs API.i record audio from react and post it to nodejs.but google API result is empty.how can I fix it?
why getting always empty results?
that's my code.
ReactMic Recorder
<ReactMic
record={record}
className="sound-wave"
onStop={onStop}
onData={onData}
strokeColor="#000000"
backgroundColor="#FF4081"
mimeType="audio/wav"/>
<button onClick={startRecording} type="button">Start</button>
<button onClick={stopRecording} type="button">Stop</button>
NodeJs API
app.post('/SpeechConvert', (req, res) => {
const client = new speech.SpeechClient();
console.log(req.files.file);
req.files.file.mv('./input.wav',function (err) {
if (err) {
console.log(err);
}
})
async function speechToText() {
// The name of the audio file to transcribe
const fileData = req.files.file.data;
// Reads a local audio file and converts it to base64
const file = fs.readFileSync('input.wav');
const audioBytes = fileData.toString('base64');
// console.log(audioBytes);
// The audio file's encoding, sample rate in hertz, and BCP-47 language code
const audio = {
content: audioBytes,
};
const config = {
enableAutomaticPunctuation: true,
encoding: 'LINEAR16',
sampleRateHertz: 44100,
languageCode: 'en-US',
};
const request = {
audio: audio,
config: config,
};
// Detects speech in the audio file
const [response] = await client.recognize(request);
console.log(response);
const transcription = response.results
.map(result => result.alternatives[0].transcript)
.join('\n');
console.log(`Transcription: ${transcription}`);
res.send({ 'transcription': transcription, 'msg': 'The Audio successfully converted to the text' });
}
speechToText().catch(console.error);
});
can anyone help me to fix this?
