The speak-punctuation property is used in aural media to specify how punctuation (i.e. comma) should be spoken.
code − Punctuation is spoken literally; e.g.,In closing, I fee that will be read as "In closing comma I feel that".
none − Punctuation is rendered as pauses of various length.
object.style.speakPunctuation = "code";
All the HTML elements.
Here is the example −
<style type = "text/css"> <!-- *.literal {speak-punctuation: code;} body {speak-punctuation: none;} --> </style>
