{{APIRef("Web Speech API")}}{{SeeCompatTable}}
The processLocally property of the
{{domxref("SpeechRecognition")}} interface specifies whether speech recognition must be performed locally on the user's device.
See On-device speech recognition for more information.
A boolean value.
true, speech recognition done via the SpeechRecognition object must be done locally.false (the default), the user agent can choose whether to do the processing locally or remotely.The following code creates a new SpeechRecognition object instance using the {{domxref("SpeechRecognition.SpeechRecognition", "SpeechRecognition()")}} constructor, then specifies that it should use local processing by setting processLocally to true:
const recognition = new SpeechRecognition();
recognition.processLocally = true;
This code is excerpted from our on-device speech color changer (run the demo live). See Using the Web Speech API for a full explanation.
