These limits are the same regardless if you are on a monthly or yearly plan or if you're on a Single or Team subscription and the limit depends on which voice type you're using.
When you open the voice settings in the app, the voices are categorized as AI or LLM. AI Voices are the standard voices. LLM Voices include both Multi-Lingual Voices and Cloned Voices.
If you reach your character limit for either AI or LLM Voices, you can buy additional credits to extend your usage.
