SpeechRecognitionAlternative: transcript property

The transcript read-only property of the SpeechRecognitionResult interface returns a string containing the transcript of the recognized word(s).

For continuous recognition, leading or trailing whitespace will be included where necessary so that concatenation of consecutive SpeechRecognitionResults produces a proper transcript of the session.

Value

A string.

Examples

This code is excerpted from our Speech color changer example.

js

recognition.onresult = (event) => {
  // The SpeechRecognitionEvent results property returns a SpeechRecognitionResultList object
  // The SpeechRecognitionResultList object contains SpeechRecognitionResult objects.
  // It has a getter so it can be accessed like an array
  // The first [0] returns the SpeechRecognitionResult at position 0.
  // Each SpeechRecognitionResult object contains SpeechRecognitionAlternative objects
  // that contain individual results.
  // These also have getters so they can be accessed like arrays.
  // The second [0] returns the SpeechRecognitionAlternative at position 0.
  // We then return the transcript property of the SpeechRecognitionAlternative object
  const color = event.results[0][0].transcript;
  diagnostic.textContent = `Result received: ${color}.`;
  bg.style.backgroundColor = color;
};
