Field Value

Attributes

Remarks

Starts an activity that will prompt the user for speech and send it through a speech recognizer. The results will be returned via activity results (in Activity#onActivityResult, if you start the intent using Activity#startActivityForResult(Intent, int)), or forwarded via a PendingIntent if one is provided.

Starting this intent with just Activity#startActivity(Intent) is not supported. You must either use Activity#startActivityForResult(Intent, int), or provide a PendingIntent, to receive recognition results.

The implementation of this API is likely to stream audio to remote servers to perform speech recognition which can use a substantial amount of bandwidth.

NOTE: There may not be any applications installed to handle this action, so you should make sure to catch ActivityNotFoundException.
