SpeechRecognition: result event

{{APIRef("Web Speech API")}}

The result event of the Web Speech API is fired when the speech recognition service returns a result — a word or phrase has been positively recognized and this has been communicated back to the app

Syntax

addEventListener("result", (event) => { })

onresult = (event) => { }

Event properties

In addition to the properties listed below, properties from the parent interface, {{domxref("Event")}}, are available.

• {{domxref("SpeechRecognitionEvent.emma")}} {{ReadOnlyInline}}
  • : Returns an Extensible MultiModal Annotation markup language (EMMA) — XML — representation of the result.
• {{domxref("SpeechRecognitionEvent.interpretation")}} {{ReadOnlyInline}}
  • : Returns the semantic meaning of what the user said.
• {{domxref("SpeechRecognitionEvent.resultIndex")}} {{ReadOnlyInline}}
  • : Returns the lowest index value result in the {{domxref("SpeechRecognitionResultList")}} "array" that has actually changed.
• {{domxref("SpeechRecognitionEvent.results")}} {{ReadOnlyInline}}
  • : Returns a {{domxref("SpeechRecognitionResultList")}} object representing all the speech recognition results for the current session.

Examples

This code is excerpted from our Speech color changer example.

You can use the result event in an addEventListener method:

const recognition = new SpeechRecognition();

recognition.addEventListener("result", (event) => {
  const color = event.results[0][0].transcript;
  diagnostic.textContent = `Result received: ${color}.`;
  bg.style.backgroundColor = color;
});

Or use the onresult event handler property:

recognition.onresult = (event) => {
  const color = event.results[0][0].transcript;
  diagnostic.textContent = `Result received: ${color}.`;
  bg.style.backgroundColor = color;
};
