What is Hei.io?
Hei.io translates audio and video into other languages, generating AI voiceovers, captions and translated subtitles. Content creators and business teams use it to reach audiences who speak other languages without hiring voice talent.
The site lists more than 440 AI voices across over 140 languages, plus voice cloning so a translated track can keep the speaker's own sound. Auto captioning handles transcription and timing, and you can import SRT or VTT files for subtitle work.
Paid plans add premium voices, custom dictionaries for terminology and an AI rewrite option, with API access on the custom tier. Billing is by minutes of processed media, either through a subscription or pay as you go.
