SpeechRecognitionResultList
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
The SpeechRecognitionResultList interface of the Web Speech API represents a list of SpeechRecognitionResult objects, or a single one if results are being captured in non-continuous mode.
Instance properties
SpeechRecognitionResultList.lengthRead only-
Returns the length of the "array" — the number of
SpeechRecognitionResultobjects in the list.
Instance methods
SpeechRecognitionResultList.item-
A standard getter that allows
SpeechRecognitionResultobjects in the list to be accessed via array syntax.
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; }; Specifications
