SpeechRecognition.interimResults

The interimResults property of the SpeechRecognition interface controls whether interim results should be returned (true) or not (false.) Interim results are results that are not yet final (e.g. the SpeechRecognitionResult.isFinal property is false.)

The default value for interimResults is false.

Value

A boolean value representing the state of the current SpeechRecognition's interim results. true means interim results are returned, and false means they aren't.
