我想在Framer(coffeescript(中构建一个函数，在那里我可以说一个特定的单词作为语音输入，然后会发生一些事情。例如，我说"苹果"，然后一个矩形变成绿色。如果我说"香蕉"，它会变成黄色。
到目前为止，它只工作一次，然后我必须刷新原型才能录制一个新单词。我怎样才能让它流利，这样我就可以说更多的单词并总是改变颜色？
这是我当前的代码。我使用Google Chrome API进行语音识别，因此原型本身只有在Chrome浏览器中打开时才有效。
SpeechRecognition = window.SpeechRecognition or
window.webkitSpeechRecognition
recognizer = new SpeechRecognition
recognizer.lang = 'de-DE'
recognizer.continuous = true
recognizer.interimResults = true
recognizer.start()
recognizer.onresult = (event) ->
result = event.results[event.resultIndex]
if result[0].transcript is "Apfel"
rect.backgroundColor = "green"
else if result[0].transcript is "Banane"
rect.backgroundColor = "yellow"
return
使用前缀属性webkitSpeechRecognition()和webkitSpeechGrammarList()。只能让引擎将"red"识别为输入语法，尽管result事件被多次触发。
