If not, where can I find good and free voices on vapi?

You can’t use 11Labs voices on Vapi free plan, only Vapi built-in voices are available for free. 11Labs integration requires a paid 11Labs API plan..

thx my friend. I'm working on a project that will need around 40,000 minutes of voice generation per month, using Growth Plan, and I really liked the voices from ElevenLabs. Which paid plan would be the best option for this kind of usage? I'm a bit confused about how the pricing works for higher volumes, so I’d really appreciate your guidance on the best plan for my case.

Hey, I can help with that. For around 40,000 minutes of voice generation per month, the Growth Plan would be a good fit, but you might want to consider the Pro Plan as well, depending on your specific needs and usage. The pricing for higher volumes typically offers better rates, so I recommend checking the details on our pricing page. Let me know if you need more specific information or have any other questions!
