SpeechRecognitionResultList
SpeechRecognitionResultList 是 Web 语音 API 的一个接口，它表示一个 SpeechRecognitionResult 对象列表，或者如果结果在 非连续 模式下捕获，则表示单个对象。
实例属性
SpeechRecognitionResultList.length只读-
返回“数组”的长度——列表中
SpeechRecognitionResult对象的数量。
实例方法
SpeechRecognitionResultList.item-
一个标准的 getter，允许通过数组语法访问列表中的
SpeechRecognitionResult对象。
示例
此代码摘录自我们的 语音颜色更改器 示例。
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;
};
