Their platform offers multiple text-to-speech models optimized for different use cases: Flash delivers sub-100ms latency ideal for real-time voice agents, Multilingual provides consistent high-fidelity speech across 29+ languages, and their latest model offers unprecedented emotional expressiveness and delivery control.

Beyond text-to-speech, ElevenLabs offers a comprehensive audio AI toolkit including industry-leading speech-to-text with 98% accuracy, professional voice cloning that captures unique vocal characteristics, and voice changing capabilities that give users precise control over timing, inflection, and emotion.

Vapi and ElevenLabs together deliver voice AI agents with unmatched audio quality and natural conversational flow. By integrating ElevenLabs' text-to-speech models into Vapi's voice agent platform, developers can build agents that sound genuinely human rather than robotic.

The integration leverages ElevenLabs' Flash model for low-latency conversational scenarios where response time is critical, enabling smooth back-and-forth dialogue without awkward pauses. For applications requiring multilingual support, the Multilingual model maintains consistent voice quality and natural pronunciation across 29+ languages, allowing businesses to deploy voice agents globally without compromising on audio fidelity.
