CSS 聽覺 參考


聽覺樣式表

聽覺樣式表結合了語音合成和聲音效果,讓使用者聽取資訊,而不是閱讀資訊。

聽覺呈現可以用於

  • 盲人
  • 幫助學習閱讀的使用者
  • 幫助有閱讀困難的使用者
  • 家庭娛樂
  • 在汽車裡
  • 有閱讀障礙的社群

聽覺呈現將文件轉換為純文字,然後將其提供給螢幕閱讀器(一種讀取螢幕上所有字元的程式)。

聽覺樣式表的示例

@media aural {
  h1, h2, h3, h4 {
    voice-family: male;
    richness: 80;
    cue-before: url("beep.au")
  }
}

上面的例子將使語音合成器播放一個聲音,然後用非常豐富的男性聲音說出標題。

注意: aural CSS 媒體型別已被棄用。
