API limit for Google Android Speech recognition

Question

Android has a speech recognition API well documented over here. Now, if I plan to integrate this in my application, I want to know what is limit to the API calls/requests that I can make to the Google server using Speech API.

Is this commercially free to use or does Google provide usage plans for the same. Does anyone know about pricing etc?

Please let me know in case you have used Speech API for Android only.

Answer 1

I've never used this API, but as far as I can tell, if the Service doesn't request credentials like an API Key, there's probably not a great way for them to track or limit your usage.

Since you're launching a Google Intent for speech recognition, it's actually google making the request to their own Services for a recognition.

I doubt there are any limits or costs, unless you've heard about otherwise.
