speech recognition - Android, convert call stream to text possible? -

i have simple application needs phone call number , speech-to-text (as best possible) whatever other party saying.

simply put, if other party says "hello", "hello" displayed on screen.

i can create phone call using intent.action_call:

intent callintent = new intent(intent.action_call); callintent.setdata(uri.parse("tel:91234567")); startactivity(callintent);

however, how go on there, convert received sound signals text?

in android, cannot access or modify phone call sound stream. due this, cannot beingness spoken, , hence cannot convert text.

this app isn't possible on android.
