SpeechRecognitionAlternative: transcript プロパティ
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
transcript は SpeechRecognitionResult インターフェイスの読み取り専用プロパティで、認識した語の記録を含む文字列を返します。
連続認識において、連続した SpeechRecognitionResult の連結がセッションの適切な記録を生成するように、必要に応じて先頭または末尾にホワイトスペースが含まれます。
値
文字列です。
例
このコードは、 Speech color changer から抜き出しています。
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;
};
