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 SpeechRecognitionResult
s
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;
};
