Deepgram
- +Mature, competitive STT (Nova) with low per-minute pricing and strong streaming
- +Rare true self-hosted, on-prem, and air-gapped options for regulated and government use
- +A single Voice Agent API collapses the STT-LLM-TTS stack
- -Infrastructure, not a finished product: you build the agent and UX yourself
- -The Voice Agent API is materially pricier, and connection-time billing can surprise
ElevenLabs Agents
- +LLM-agnostic on top of best-in-class proprietary text-to-speech and its own speech-to-text
- +Strong first-class telephony story (Twilio, SIP, multiple carriers) with sub-second latency
- +Flexible build paths: no-code builder, SDKs, WebSocket API, function calling, and MCP
- -Layered, recently changed pricing (bundled minutes plus overage plus pass-through LLM cost) makes total cost hard to predict
- -Autonomy is bounded to configured tools, not autonomous out of the box
