Hi @Amit Samuel , Thanks for using Microsoft Q&A Platform.
Have you tried with Speech Synthesis Markup Language (SSML). The say-as element helps in text pronunciation.
Here is a currency interpretation example. If you haven't tried it yet, please do so and let us know how that works.
Please include more information, how you are actually trying these using the REST API or any specific SDK or in studio.
I hope this helps.
Regards,
Vasavi
