SpeechRecognitionResult

Limited availability

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

TheSpeechRecognitionResult interface of theWeb Speech API represents a single recognition match, which may contain multipleSpeechRecognitionAlternative objects.

Instance properties

SpeechRecognitionResult.isFinalRead only: A boolean value that states whether this result is final (true) or not (false) — if so, then this is the final time this result will be returned; if not, then this result is an interim result, and may be updated later on.
SpeechRecognitionResult.lengthRead only: Returns the length of the "array" — the number ofSpeechRecognitionAlternative objects contained in the result (also referred to as "n-best alternatives".)

Instance methods

SpeechRecognitionResult.item: A standard getter that allowsSpeechRecognitionAlternative objects within the result to be accessed via array syntax.

Examples

This code is excerpted from ourSpeech color changer example.

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