SpeechRecognition: interimResults property
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
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.
