SpeechRecognitionResultList
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Die SpeechRecognitionResultList-Schnittstelle der Web Speech API repräsentiert eine Liste von SpeechRecognitionResult-Objekten, oder ein einzelnes Objekt, wenn Ergebnisse im non-continuous-Modus erfasst werden.
Instanz-Eigenschaften
SpeechRecognitionResultList.lengthSchreibgeschützt-
Gibt die Länge des "Arrays" zurück — die Anzahl der
SpeechRecognitionResult-Objekte in der Liste.
Instanz-Methoden
SpeechRecognitionResultList.item-
Ein Standard-Getter, der es ermöglicht, auf
SpeechRecognitionResult-Objekte in der Liste über Array-Syntax zuzugreifen.
Beispiele
Dieser Code ist ein Auszug aus unserem Speech color changer-Beispiel.
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;
};
