SpeechRecognitionErrorEvent: SpeechRecognitionErrorEvent() constructor

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The SpeechRecognitionErrorEvent() constructor creates a new SpeechRecognitionErrorEvent object instance.

Syntax

new SpeechRecognitionErrorEvent(type, init)

Parameters

type

A string containing the name of the event. This will always be error.

init

An initialization object that contains the following properties:

error: An enumerated value representing the type of error. See the possible error values.
message Optional: A string containing more details about the error that was raised. Note that the specification does not define the exact wording of these messages — implementers must define their own wording.

Examples

You would be unlikely to construct a SpeechRecognitionErrorEvent instance manually. Such instances are available as event objects inside error event handler functions.

For example:

const recognition = new SpeechRecognition();

recognition.addEventListener("error", (event) => {
  console.log(`Speech recognition error detected: ${event.error}`);
  console.log(`Additional information: ${event.message}`);
});
