Voice and Spanish
On Vapi, Spanish sounds like whatever voice provider you connect: quality and accent depend on that provider, and Vapi doesn't document Latin American accents. Fonema includes 200+ regional voices by country and detects when a caller switches to English mid-call.
Real price
Vapi charges $0.05 USD per platform minute; transcription, language model, voice and telephony are paid separately, each at its own rate. Third-party estimates put the total at $0.13 to $0.33 per minute. On Fonema the agent is a single rate: $0.14 USD per minute, billed per second, with automatic volume discounts and no charge for unanswered calls; telephony runs at Twilio's per-country rate or over your own SIP trunk.
Setup
Vapi is built for engineers: it's configured via API and retired its visual builder in August 2026. Fonema is configured without code, with onboarding in Spanish or English.
