How and where is SSML used?

Speech Synthesis Markup Language (SSML) is often created using an SSML Extensible Markup Language (XML) text editor. SSML tags are applied to text to get an audio output. Computers do not know how to speak without SSML and tagging. For example, without the SSML <break> tag, we cannot apply pauses in speech between words or paragraphs in sentences. The <say-as> tag determines how numbers are translated. For example, the ordinal attribute for the <say-as> tag interprets the number 85 as eighty five in the audio output. The cardinal attribute for the <say-as> tag interprets the number 85 as eighty fifth in the audio output.

SSML can be used in telephony applications for surveys and marketing purposes. It is also used for audio books, appliance operational commands, robotics, website navigation, voice overs, and many other audio uses. Any application where text-to-speech is required, SSML can be used.
