Is it possible to intercept audio data using google+ hangout api? I writing an app using g+ hangout for android and I would like to process the audio. To be precessive, I want to denoise speech and use speech-to-text (e.g. google search, sphinx) to make basic voice commands.
Because I have full control of the android app it doesn’t matter for me if I will have a callback with audio data from hangout or I can record audio using android AudioRecorder and then somehow forward those data to google hangout (Though the latter solution would be better because we can denoise on the android device). Actually I would be happy with any feasible workaround that may work at this stage of the API.
The Hangouts API is not going to help you develop this feature.
What you need is a platform agnostic API for accessing hangouts data. The API is instead intended to solve a different problem. It allows you to write HTML/JavaScript applications that run inside the canvas of hangouts running on desktop web browsers.
