如何使用Web Speech API来监听文本区各行的单词，每行都是延迟的？

if ('SpeechRecognition' in window || 'webkitSpeechRecognition' in window) {
  // 浏览器支持 Web Speech API
} else {
  // 浏览器不支持 Web Speech API
}

const recognition = new SpeechRecognition() || new webkitSpeechRecognition();
recognition.interimResults = true; // 开启中间结果

const textarea = document.querySelector('textarea');
textarea.addEventListener('input', () => {
  const lines = textarea.value.split('\n');
  lines.forEach((line, index) => {
    setTimeout(() => {
      processLine(line);
    }, index * 1000); // 根据需要设置延迟时间
  });
});

function processLine(line) {
  recognition.start();
  recognition.onresult = (event) => {
    const transcript = event.results[0][0].transcript;
    const words = transcript.split(' ');
    // 处理单词
    console.log(words);
  }
  recognition.stop();
}
