SpeechRecognitionResult

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

Instance properties

• 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.
• 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

• 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;
};
