I need to use speech input to insert text. How can i detect keyword when I’m speaking ?

Can i do this with Android Speech Input or I need external library ?

Keyword detection task is different from a speech recognition task. While second tries to understand the text being spoken and check all possible word combinations, keyword spotting usually check two hypothesis – word is here or garbage is here. Its way more efficient to check keyword presence but it requires custom algorithm. You can implement one with the open source speech recognition toolkit like CMUSphinx.

Which runs on Android too, you can check
