Azure speech to text in react-native wav file pass issue - azure

Question

I want use Azure's STT REST API for my react-native app with recorded audio.
But I've try to search how to pass the wav file but always response "No audio data received" or other error response.
I'm very sure the subscribe key is working cause when I use get token it responses 200.
And the wav file is not the problem,either.Cause when I download the file to my computer then upload it in Azure STT's homepage,it responses the correct answer.
The last,I've tried to figure out how to pass it in right form,but every things are for website.
Here's my code
`
const file = new ReactNativeFile({
uri:
`file://${audioFile}`,
type: 'audio/wav',
name: 'ABCS160101e1a011b160a3e169d7b0.wav',
});
let form = new formData();
const headers = {
'Ocp-Apim-Subscription-Key': 'MyKey',
'Content-type': 'audio/wav; codecs=audio/pcm;samplerate=16000',
Accept: 'application/json',
};
const url = `https://eastasia.stt.speech.microsoft.com/speech/recognition/conversation/cognitiveservices/v1?language=en-US`;
await form.append('audio', file);
console.log('before');
let response = await axios.post(url, form, {
headers: headers,
});
console.log('after');
console.log('result', JSON.stringify(response));
} catch (err) {
getlog.cw('err23', err);
return err;
}
};`
and Here's My recording function in another place,it's working for play.
import AudioRecord from 'react-native-audio-record';
const options = {
sampleRate: 16000, // default 44100
bitsPerSample: 16, // 8 or 16, default 16,
wavFile: "ABCS160101e1a011b160a3e169d7b0.wav"
};
const toggleRecord = async () => {
if (isRecording) {
const audioFile = await AudioRecord.stop();
setIsRecording(false);
// reloadRecorder();
} else {
setIsRecording(true);
AudioRecord.init(options);
AudioRecord.start();
}
};

Answer 1

Firstly, write
let form = new FormData();
Instead of
let form = new formData();
Secondly, I suppose you audioFile looks like this - file://.... So you dont have to write like this uri: file://${audioFile} ..You can simply write
uri:audioFile
SO final implementation would be
let form = new FormData();
form.append('audio', {
uri: audioFile,
type: 'audio/wav',
name: 'ABCS160101e1a011b160a3e169d7b0.wav',
});
const headers = {
'Ocp-Apim-Subscription-Key': 'MyKey',
'Content-type': 'audio/wav; codecs=audio/pcm;samplerate=16000',
Accept: 'application/json',
};
const url = `https://eastasia.stt.speech.microsoft.com/speech/recognition/conversation/cognitiveservices/v1?language=en-US`;
console.log('before');
let response = await axios.post(url, form, {
headers: headers,
});
console.log('after');
console.log('result', JSON.stringify(response));
