Grammar in Google Web Speech API

Question

Can I improve Google speech API recognition by give him a words list (in my case the request of user is very predictable) to make recognition more accurate?

Answer 1

I can't speak for Chrome, but in Android they are quite clear that you cannot provide a grammar. In Android speech recognition you are limited to a choice of two models: "free form" and "web search".
