Can we add custom language for RecognizerIntent?
I have search many SO Question like https://stackoverflow.com/questions/2080401/is-there-a-speech-to-text-api-by-google<
Google will unlikely support small languages any time soon. The only way to custom language is to train CMUSphinx model and use it with Pocketsphinx:
