TheprocessLocally property of theSpeechRecognition interface specifies whether speech recognition must be performed locally on the user's device.

SeeOn-device speech recognition for more information.

Value

A boolean value.

• If set totrue, speech recognition done via theSpeechRecognition object must be done locally.
• If set tofalse (the default), the user agent can choose whether to do the processing locally or remotely.

Examples

Basic usage

The following code creates a newSpeechRecognition object instance using theSpeechRecognition() constructor, then specifies that it should use local processing by settingprocessLocally totrue:

const recognition = new SpeechRecognition();recognition.processLocally = true;

This code is excerpted from ouron-device speech color changer (run the demo live). SeeUsing the Web Speech API for a full explanation.
