Directory
AI audio and speech covers voice synthesis, transcription, and machine learning tools for sound. Listings include text to speech services, dictation and meeting transcription, voice cloning, music generation, and open source models you can run yourself. The languages and accents each one handles matter, along with the length limit for a single job and whether processing happens on your device or on a remote server. Quality and cost also move, since some services change their limits often and a model you can host yourself behaves differently from a hosted one. Voice cloning and generated speech raise consent and rights questions, so use your own recordings or material you are allowed to use.
