Specifies a string of text to speak in place of the text contained in the element.
Required. Specifies the substitute text to speak.
Before synthesizing a phrase, the text-to-speech (TTS) engine normalizes it. The normalization process converts symbols, numbers, and other non-orthographic entities into text representing the spoken value of these entities. For example, normalization converts "$1.99" into "one dollar and ninety-nine cents."
Use a sub element to create a custom text value for any text element. Because the TTS engine processes sub elements before normalizing the phrase, the substitute text is normalized before being synthesized.
