What technology stack sits behind NestVoice AI?
A voice agent is an orchestration of four replaceable layers: carriers that carry the call, speech recognition that transcribes it, reasoning models that decide what to say, and neural synthesis that speaks it. NestVoice AI keeps each layer pluggable so a model or carrier can be swapped without rebuilding the agent.
- Carriers
- Twilio, Telnyx, Plivo, FreeSWITCH, Asterisk, Kamailio
- Synthesis
- Cartesia, ElevenLabs, PlayHT, Sarvam AI
- Reasoning
- Gemini, Claude, DeepSeek, GPT-class models
- Portability
- Every layer swappable — BYOK on model and carrier
