Thank you for reaching out to Microsoft Q&A forum!
In Azure Text-to-Speech, it's possible to have numbers like "257" spoken as "two hundred fifty seven" without including the "and." To achieve this, I replicated the process by selecting the number from the input text (e.g. 257). On the right side of the section navigate to the Pronunciation section> select Reading rules> select Number from drop down. Playing the audio confirmed the correct pronunciation. Please look into the below screenshot.
Hope this helps. Do let us know if you any further queries.
