AI voice generators: what they are and who makes them
ElevenLabs, WellSaid, Speechify Studio and 6 more, sorted into types, with the company behind each and where it is based.
Types of AI voice generators
Creator studios with a voice library
ElevenLabs, Speechify Studio and WellSaid sell a browser studio where you paste a script, pick a voice, adjust delivery and download audio. Plans are metered in credits or download minutes, and the plan tier decides whether you may use the result commercially.
Developer text-to-speech APIs
Cartesia, Google Cloud, Azure and Amazon Polly bill per character or per token and are meant to be called from code. They suit voice agents, apps and accessibility features, where latency and unit cost matter more than a polished editor.
Voice cloning and custom voices
ElevenLabs, Cartesia, Descript and the cloud providers let you build a voice from recordings, from a quick instant clone to a studio-grade professional clone. Higher tiers usually require proof that the speaker consented, and some providers gate the feature behind an approval step or a business plan.
Video and podcast editors with built-in speech
Descript treats generated speech as one feature inside a text-based audio and video editor. You correct a mistake by typing, and the editor regenerates the line in a cloned or stock voice. It trades voice depth for an all-in-one workflow.
