这是实验性技术
检查浏览器兼容性表格要小心谨慎在生产中使用这之前。

SpeechSynthesisEvent 接口在 Web 语音 API contains information about the current state of SpeechSynthesisUtterance objects that have been processed in the speech service.

特性

SpeechSynthesisEvent interface also inherits properties from its parent interface, 事件 .

SpeechSynthesisEvent.charIndex 只读: Returns the index position of the character in the SpeechSynthesisUtterance.text that was being spoken when the event was triggered.
SpeechSynthesisEvent.elapsedTime 只读: Returns the elapsed time in milliseconds after the SpeechSynthesisUtterance.text started being spoken that the event was triggered at.
SpeechSynthesisEvent.name 只读: Returns the name associated with certain types of events occuring as the SpeechSynthesisUtterance.text is being spoken: the name of the SSML marker reached in the case of a mark event, or the type of boundary reached in the case of a boundary 事件。
SpeechSynthesisEvent.utterance 只读: 返回 SpeechSynthesisUtterance instance that the event was triggered on.

方法

范例

utterThis.onpause = function(event) {
  var char = event.utterance.text.charAt(event.charIndex);
  console.log('Speech paused at character ' + event.charIndex + ' of "' +
  event.utterance.text + '", which is "' + char + '".');
}
utterThis.onboundary = function(event) {
  console.log(event.name + ' boundary reached after ' + event.elapsedTime + ' milliseconds.');
}
