Simple markup tips for writing text-to-speech:
When saying numbers, '12345' will be spoken as "twelve thousand three hundred forty five." Whereas '1 2 3 4 5' will be spoken as "one two three four five."
Punctuation such as commas and periods will be interpreted as natural pauses by the speech engine.
Combine punctuation, for example periods, to create longer pauses.
