Google Speech To Text API in React Native - react-native

Question

I'm doing a project by React Native with following features
1. Users start recording audio
2. Stop recording audio
3. Save audio
4. Translate it to text (In my case translate to Vietnamese)
I'm done with 1,2,3. But I'm stuck at 4, I don't know how to use Google STT API with an audio file input, because it seems like just use STT as an intent.
Hope any ideas or solution related!
Here's my code:
requestAPI() {
// Imports the Google Cloud client library
const Speech = require('#google-cloud/speech')({
projectId: 'speech-to-text-175801',
keyFilename: '/keyfile.json'
});
const RNFS = require('react-native-fs');
// Your Google Cloud Platform project ID
const projectId = 'speech-to-text-175801';
// Instantiates a client
const speechClient = Speech({
projectId: projectId,
keyFilename: '/keyfile.json'
});
// The name of the audio file to transcribe
const fileName = this.state.audioPath;
// Reads a local audio file and converts it to base64
const file = RNFS.readFile(fileName);
const audioBytes = file.toString('base64');
// The audio file's encoding, sample rate in hertz, and BCP-47 language code
const audio = {
content: audioBytes
};
const config = {
encoding: 'aac',
sampleRateHertz: 32000,
languageCode: 'vi-VN'
};
const request = {
audio: audio,
config: config
};
// Detects speech in the audio file
speechClient.recognize(request)
.then((results) => {
const transcription = results[0].results[0].alternatives[0].transcript;
this.setState({
textReceived: transcription
})
})
.catch((err) => {
this.setState({
textReceived: 'Có lỗi Google Cloud STT, mời bạn request lại'
})
});
}
Error now: 'Unable to resolve module "child_process" from ...\google-auth-library\lib\auth\googleauth.js"

Answer 1

I think the problem is that you can't use Google speech SDK on react native, it's a node library. So you need to first send your file to nodejs server then call the sdk methods.

You can use react-native-speech-to-text-android to perform speech to text conversion.
import SpeechToText from 'react-native-google-speech-to-text';
const speechToTextHandler = async () => {
let result = null;
try {
result = await SpeechToText.startSpeech('Try saying something', 'en_IN');
console.log('Result: ', result);
} catch (error) {
console.log('error: ', error);
}
}
