Dear Annabelle Baradine,
Thank you for reaching out to the Microsoft Q&A.
Yes, you are correct. Since Microsoft acquired Nuance Communications, the Nuance Text-to-Speech technology has been integrated into Microsoft's Azure AI platform. The old Nuance demo has been retired.
The new demo is now part of the Azure AI Speech Studio. While this platform features a vast library of high-quality, natural-sounding neural voices, the specific branded voices from Nuance Vocalizer Expressive (like Evan, Zoe, Samantha, and Tom) are generally not available under their old names.
You can try the powerful new text-to-speech platform, which is the spiritual successor to the Nuance demo, at the link below. You'll find a wide selection of languages and voices, with extensive controls for speaking style, role, and emotion.
Try the demo here: Microsoft Azure Text-to-Speech Studio
While you won't find a voice specifically named "Tom" or "Samantha," you can explore the available options to find one with similar characteristics (gender, accent, and tone) that suits your needs.
