java - Converting recorded audio to text in android studio

Question

I am making a custom keyboard app in which I want to add a microphone also. I want to record the audio and convert it to text. The tutorials available on the internet uses intent ( for calling another activity from the main activity). Since my app has no main activity, I am unable to use those tutorials for my code. I am able to record the audio in 3gp or mp3 format. I want to convert this to text. Could somebody please help me with this issue?

Recording audio:

        mic_key = new MediaRecorder();
        mic_key.setAudioSource(MediaRecorder.AudioSource.MIC);
        mic_key.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
        mic_key.setAudioEncoder(MediaRecorder.OutputFormat.AMR_NB);
        mic_key.setOutputFile(audio_file);

    private void speak()
    {
        try
        {
            mic_key.prepare();
            mic_key.start();
        } catch (IOException e) {
            e.printStackTrace();
        }
        Toast.makeText(EDMTKeyboard.this, "Recording Started", Toast.LENGTH_SHORT).show();
    }
    
    private void stop()
    {
        mic_key.stop();
        mic_key.release();


        Toast.makeText(EDMTKeyboard.this, "Recording Done", Toast.LENGTH_SHORT).show();
    }
