- 文字轉(zhuǎn)語(yǔ)音實(shí)現(xiàn)
基于瀏覽器提供的SpeechSynthesisUtterance Api進(jìn)行實(shí)現(xiàn)
SpeechSynthesisUtterance基本屬性
SpeechSynthesisUtterance.lang獲取并設(shè)置話語(yǔ)的語(yǔ)言SpeechSynthesisUtterance.pitch獲取并設(shè)置話語(yǔ)的音調(diào)(值越大越尖銳,越低越低沉)SpeechSynthesisUtterance.rate獲取并設(shè)置說(shuō)話的速度(值越大語(yǔ)速越快,越小語(yǔ)速越慢)SpeechSynthesisUtterance.text獲取并設(shè)置說(shuō)話時(shí)的文本SpeechSynthesisUtterance.voice獲取并設(shè)置說(shuō)話的聲音SpeechSynthesisUtterance.volume獲取并設(shè)置說(shuō)話的音量
SpeechSynthesisUtterance.text基本方法
speak()將對(duì)應(yīng)的實(shí)例添加到語(yǔ)音隊(duì)列中cancel()刪除隊(duì)列中所有的語(yǔ)音.如果正在播放,則直接停止pause()暫停語(yǔ)音resume()恢復(fù)暫停的語(yǔ)音
為按鈕添加點(diǎn)擊事件，獲取input輸入框的值，并進(jìn)行播放，添加眼睛動(dòng)畫，并在播放結(jié)束的回調(diào)移除眼睛動(dòng)畫
$('#btn').click(function () { let text = $('#input').val() if (text) { $('.eye').addClass('shine') } let u = new window.SpeechSynthesisUtterance() u.text = text u.lang = 'zh' u.rate = 0.7 u.onend = function () { $('.eye').removeClass('shine') } speechSynthesis.speak(u) })
