Product Overview
What is Speko?
Speko is a developer platform for production voice agents. It provides a hosted router that unifies speech-to-text, language model, and text-to-speech providers behind a single API, selecting providers based on language, latency, cost, and availability. Speko also offers managed voice agents for browser and phone deployments, an open-source gateway for provider-direct workloads, SDKs for TypeScript and Python, and MCP tools for agent-assisted development and operations.
Key Features
Multi-Provider Voice Routing
Routes STT, LLM, and TTS requests through a unified API, allowing applications to use multiple voice providers without maintaining separate integrations.
Benchmark-Based Model Selection
Uses language-specific benchmarks for accuracy, latency, and pricing to select suitable speech and voice models for each workload.
Automatic Failover
Retries requests with alternative providers when a primary provider fails, helping voice applications remain available during service disruptions.
Managed Voice Agents
Lets teams configure reusable voice agents with prompts, voices, tools, knowledge sources, routing preferences, and deployment settings.
Browser and Telephony Deployment
Supports running the same voice agent in browser-based conversations as well as inbound and outbound phone calls.
Developer Integrations
Provides TypeScript, Python, browser, and LiveKit SDKs, plus MCP support for building, testing, deploying, and inspecting voice agents.
Use Cases
- Customer Support Voice Agents : Build phone or web voice assistants that answer customer questions, access knowledge sources, transfer calls, and record interaction outcomes.
- Multilingual Voice Products : Deliver speech experiences across languages while routing requests to models that perform well for each target language.
- Voice Provider Reliability : Reduce dependency on a single STT, LLM, or TTS vendor by using routing and failover across supported providers.
- Voice Agent Prototyping : Launch and evaluate conversational voice agents quickly using managed configuration, SDKs, and prebuilt integrations.
- Private Voice Infrastructure : Run provider-direct streaming workloads with the Gateway while retaining control of credentials and media flows.
- Agent-Assisted Voice Development : Use MCP-compatible coding tools to create, deploy, test, and manage voice agents from AI development environments.
