Uttera
OpenAI-compatible audio API for speech-to-text, text-to-speech, translation, audio analysis, sound effects and music generation.
Uttera is a cloud voice and audio service operated by Uttera Labs S.L. (Madrid, Spain). It provides transcription, speech synthesis, voice cloning, voice translation, summarization, pronunciation assessment, speaker diarization, sound effect and music generation over an OpenAI-compatible HTTP API (base URL https://api.uttera.ai/v1) and an MCP server for agents. It also offers browser-based apps (Studio, Interpreter, Coach), mobile apps, and signed, verifiable PDF reports anchored to quotes and timestamps. Audio is processed in memory and discarded after the response, is not used for training, and is processed on the company's own hardware in Spain. The underlying engines are open source under Apache 2.0 and can be self-hosted.
