I'm glad you're interested in adding emotions to Text-to-Speech (TTS) in LiveKit! You can achieve this by using specific TTS plugins that support emotional voice control. Here are some options to explore: • Cartesia TTS: You can use the

emotion

parameter with the model

sonic-2-2025-03-07

. It supports emotions like anger, positivity, surprise, sadness, and curiosity, each with levels such as

:low

or

:high

. • Hume TTS: Offers detailed emotional control through its API, using emotion scores or prosody parameters to fine-tune the voice. • LMNT TTS: You can adjust emotional variation by tweaking the

temperature

parameter—higher values bring more expressiveness. • Azure Neural TTS: This one lets you use SSML tags to control tone with styles like cheerful, sad, or angry. If you let me know which TTS provider you’re working with, I’d be happy to guide you through the specifics and help you get the best emotional effect!
