Speko developer platform
Build and operate production voice AI.
Run managed agents across browser and telephony, then choose the routing, runtime, SDKs, and agent tooling that fit your architecture.
Managed Agents Platform
From persona to production call
Create reusable voice agents with their own prompt, voice, routing preferences, tools, and knowledge. Deploy them once, then use the same agent across browser sessions and phone calls.
- Define the persona and stack
- Persist the system prompt, voice, language, model settings, and STT, LLM, and TTS provider preferences.
- Connect tools and knowledge
- Give each agent its own registered tools and knowledge, including managed search, call transfer, and hangup actions.
- Run across browser and phone
- Use the same agent in browser conversations and inbound or outbound phone calls, with per-session overrides when needed.
- Operate the full lifecycle
- Deploy versions, test sessions, and inspect transcripts, recordings, lifecycle events, reports, and costs from one control plane.
Choose your integration boundary
Each surface solves a different layer of the stack. Start with one and combine them as your product grows.
Hosted API
Relay
Send one request shape to a hosted, anycast API. Speko selects a healthy provider, handles failover, and streams the result back.
