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.length Nur lesbar

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;
};
