SpeechRecognitionResult

Limited availability

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

The SpeechRecognitionResult interface of the Web Speech API represents a single recognition match, which may contain multiple SpeechRecognitionAlternative objects.

Instance properties

SpeechRecognitionResult.isFinal Read 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.length Read only: Returns the length of the "array" — the number of SpeechRecognitionAlternative objects contained in the result (also referred to as "n-best alternatives".)

Instance methods

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

Examples

This code is excerpted from our Speech color changer example.

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