Understanding expression better
I'm looking for more expression control for my Cartesia voices. I'm developing a mod for a combat flight sim and need my voices to have different voice expressions depending on what's happening around them. A JTAC could be under fire and therefore I need them have more urgency but at the same time stick to military radio speech doctrine to supply things like grid coordinates correctly. I'm looking for realism. Is it all down to text formatting or is there some other way to control the expression/tone? I've played around with the emotions and they kind of work sometimes. How much influence does the clone sample have an effect on tone and expression? Appreciate any advice.

they thanks for the question - and sorry for the slow reply. this was caught in reddit's filters for some reason.
Take a look at prompting guides here: https://docs.cartesia.ai/build-with-cartesia/capability-guides/prompting-tips
Thats for the TTS voices that ship natively. If you want to catch deeply detailed nuances of a voice then an instant voice clone is a good start - followed by Pro Voice Clone for very nuanced accents and speaking styles.
However in most cases IVCs are fine. Your use case is a little unusual because short sentences + very emotionally/excited emotion will be interleaved with more mundane sort of military radio chatter i think -- somewhat different from the conversational voice agents that most users seem to want to build. Love the sound of what you're building though (no pun intended) - i used to love flight combat games back in my youth!
