The company claims its benchmarks include ten-minute takes and spontaneous speech, and it has trained an automatic scorer for TTS naturalness based on blind head-to-head human listening votes.", "body_md": "# Speko is basically OpenRouter but for the voice AI stack\n\nSpeko solves this by acting as an intelligent router. Instead of hardcoding your providers, you send a request specifying your constraints—whether you're optimizing for latency, cost, accuracy, or a balance of all three—along with the language and region. The platform then references its own benchmarked data to route the request to the winning combination of models.\n\n## How the routing and failover work\n\nThe technical implementation is designed to avoid the \"control-plane lag\" that kills the feeling of a real-time conversation.\n\n1. **Optimization Request:** You define your criteria (e.g., \"lowest latency\" or \"highest accuracy\") and the target region.\n\n2. **Model Selection:** The router filters through its public benchmarks to find the current winner for that specific combination.\n\n3. **Session Prefetching:** To prevent the caller from waiting, the gateway prefetches signed session plans. This means the session connects to the provider directly from memory, skipping an extra round trip.\n\n4. **Connection Failover:** Failover is handled strictly during the connection setup. If the primary provider rejects the attempt, the system immediately pivots to the runner-up model.\n\nFor those who are worried about adding another network hop to their audio path or sharing API keys, they've open-sourced the gateway as a Go binary. You can run it as a sidecar in your container, communicating via a Unix socket to pin provider hosts and attach keys locally.\n\n```\n# Example of the gateway logic (Conceptual)\n# The Go binary runs as a sidecar, handling the local protocol \n# and attaching keys to the provider requests.\n```\n\n## The benchmarking approach\n\nWhat makes this actually useful is the transparency of the data. They aren't just using \"vibes\" or short 30-second clips. Their benchmarks include ten-minute takes and spontaneous speech to see which models actually hold up over a long conversation. They've even trained an automatic scorer for TTS naturalness based on blind head-to-head human listening votes, which they claim matches human rater agreement levels.\n\nSince Speko doesn't train or sell its own models, the rankings remain impartial. This is a massive win for anyone building a real-world AI workflow where switching from a mediocre STT to a high-accuracy one can be the difference between a usable product and a frustrating one.\n\nIf you're currently managing a complex voice stack, using a router like this turns a manual engineering task into a simple API call.\n\n```\nhttps://speko.ai/\n```\n\n[Go is arguably the most AI-friendly language for modern backend 5d ago](/en/news/5940/)\n\n[Next Sainsbury's just paused AI cameras after a shopper got kicked out →](/en/news/6688/)", "url": "https://wpnews.pro/news/speko-is-basically-openrouter-but-for-the-voice-ai-stack", "canonical_source": "https://promptcube3.com/en/news/6694/", "published_at": "2026-08-17 16:32:34+00:00", "updated_at": "2026-08-17 16:42:09.780297+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-infrastructure", "ai-tools"], "entities": ["Speko", "OpenRouter"], "alternates": {"html": "https://wpnews.pro/news/speko-is-basically-openrouter-but-for-the-voice-ai-stack", "markdown": "https://wpnews.pro/news/speko-is-basically-openrouter-but-for-the-voice-ai-stack.md", "text": "https://wpnews.pro/news/speko-is-basically-openrouter-but-for-the-voice-ai-stack.txt", "jsonld": "https://wpnews.pro/news/speko-is-basically-openrouter-but-for-the-voice-ai-stack.jsonld"}}
