Anyone Knows About Android 4.1+ Offline Voice-recognition Api Documentation?

I'm trying to build an offline voice recognition Android app on Android 4.1.2 and 4.3, and I'm trying to get access to Android ASR API. I could find all information related to sync

Solution 1:

Android's speech API (as of version 4.3) does not offer speech recognition of a pre-recorded audio. Also, the API does not allow the client to declare that speech recognition should happen offline.
