Best alternatives to Speko in 2026
Building a voice product usually means picking one speech AI vendor and living with its strengths and weaknesses everywhere — great English transcription but weak Mandarin, say, or natural-sounding English voices but robotic French ones. Speko sits in front of all the major voice AI providers and automatically sends each request to whichever model actually performs best for that language and task, so you get one integration instead of juggling several vendor accounts and SDKs. Technically, Speko is an OpenAI API-compatible gateway covering speech-to-text, text-to-speech, and speech-to-speech, routing across providers like OpenAI, Google, Deepgram, ElevenLabs, and Alibaba's Qwen based on published performance benchmarks per language. It supports 9+ languages, is SOC 2 Type II, HIPAA, and GDPR compliant, and integrates with voice-agent frameworks like LiveKit and Pipecat as well as MCP-based coding tools. Pricing is usage-based, running roughly $0.001–$0.017 per minute depending on which underlying model gets used for a given request. It's a Y Combinator S26 company.
