Hands-on review of Moonshine AI — an open-source on-device voice AI toolkit that runs speech-to-text, intent recognition, and neural TTS in under 500KB RAM. Outperforms Whisper Large V3 at a fraction of the size. Tests on desktop, Raspberry Pi, and microcontroller deployments.
Speko (YC S26) is an OpenRouter-style router for voice AI: one OpenAI-compatible API in front of 20+ speech-to-text models, LLMs, and TTS engines, with routing decisions based on its own continuously published benchmarks (WER vs cost per language) rather than vendor leaderboards. Router pricing is +5% on provider rates; Speko's own infrastructure is $0.09/min all-in for STT+LLM+TTS, with $100 signup credit. We break down the benchmark table, the LiveKit integration, the 'auto' model routing, and the HN debate (84 points) over whether cascaded or end-to-end voice stacks win.
