SpeechRecognizer with Audio recording in Android

Question

I want to make a speech recognizer app which transcribes the user's speech. I do not want any dialog while doing that, so startActivityForResult with recognizerIntent is out of the option. (I know I can get audio if I use this approach)

I am using SpeechRecognizer for that and call startListening to listen user's audio. I am getting results with very good accuracy in onResults.

Now, I also need the audio of user stored in sdcard in my device. For that I have tried both MediaRecorder as well as AudioRecord, but not getting any success. I am always getting Network Error in onError of RecognitionListener. I can't find anyway on how to overcome this issue. I have also tried to get data from onBufferReceived, but in vain.

If anyone can throw some light on this, then that would be great.

[Edit]

Guys, this is not a duplicate of record/save audio from voice recognition intent, it's slightly different. The answer you gave is for Google Keep. Keep uses the dialog to get data. I do not need a dialog hanging on the screen.

Answer 1

I have successfully accomplished this with the help of CLOUD SPEECH API. You can find it's demo by google speech.

The API recognizes over 80 languages and variants, to support your global user base. You can transcribe the text of users dictating to an application’s microphone, enable command-and-control through voice, or transcribe audio files, among many other use cases. Recognize audio uploaded in the request, and integrate with your audio storage on Google Cloud Storage, by using the same technology Google uses to power its own products.

It uses audio buffer to transcribe data with help of Google Speech API. I have used this buffer to store Audio recording with help of AudioRecorder.

So with this demo we can transcribe user's speech parallely with Audio Recording.
