One API for leading voice engines. Access Quantrova Ultra, Qwen3TTS, xAI, Rime, MiniMax Speech 2.8 Turbo, ResembleAI, Inworld, AWS, Azure, and more without lock-in. Built for real-time Voice AI and standalone TTS workflows.
ElevenLabs delivers strong voice quality, but you’re limited to its own models with less engine flexibility. It is often used for content creation, while real-time Voice AI may require tighter control over synthesis, routing, and delivery.
Vapi offers provider choice through orchestration, but synthesis may still depend on external TTS providers. This can add extra routing steps and create dependency on multiple services.
TTS Router helps reduce the trade-offs between voice quality, latency, cost, and engine flexibility. Quantrova gives you access to multiple TTS engines through one unified workflow designed for real-time Voice AI applications.
Most Voice AI builds start with a vendor problem: one tool for TTS, one for STT, one for telephony, and one for inference. Quantrova brings these workflows together into one flexible platform, with APIs for speech-to-text, text-to-speech, and real-time voice automation.
