[Speech to text] How do I configure the AudioConfig object to an AudioBuffer Object?

Muhsin Wahi-Anwar 1

Hello,

I'm trying to get some audio inputs working and want to use an mozilla/HTML AudioBuffer object as an input for some speech identification.

What kind of AudioConfig object should I use? Currently I'm going with
sdk.AudioConfig.fromWavFileInput(AudioBuffer);

Is this good?

Awesome. When I input an audio stream into into the audio config and use the recognizer, will the recognizer be able to 'listen' to the audio instantaneously? Or does it send the audio data in real time?

Hello,

According to the code, it has "read" and "close" sessions and it will return the data to caller.

public class ContosoAudioStream : PullAudioInputStreamCallback {
    ContosoConfig config;

    public ContosoAudioStream(const ContosoConfig& config) {
        this.config = config;
    }

    public int Read(byte[] buffer, uint size) {
        // returns audio data to the caller.
        // e.g. return read(config.YYY, buffer, size);
    }

    public void Close() {
        // close and cleanup resources.
    }
};
