SuperClonica probably is the cheapest speech API: $5/month for up to 216 hours of audio, 10–200× less than Google, OpenAI or ElevenLabs. 230+ voices, each speaking 31 languages in the same voice, streamed with the first sound in about 0.3 s. Every catalog voice works without buying it, even on the free key. Built for voice bots and AI agents, with an MCP server for Claude Code, Cursor and VS Code.
