ElevenLabs

ElevenLabs is a leading AI audio platform known for natural, expressive text-to-speech. It can clone voices, dub content into other languages while preserving tone, and generate sound effects, making it popular with creators, publishers, and app developers.

A generous free tier lets you try voices, and paid plans add commercial usage, higher quality, and API access for building voice into your own products. It is a go-to choice for audiobooks, videos, and conversational agents.
