Preserve the unique character and tone of your own voice across multiple languages. This powerful feature clones your voice, allowing you to speak fluently in languages like Spanish, French, or Japanese while maintaining your vocal identity. The result is a truly personal and authentic connection with your international audience.
字幕 Automated Transcription & Subtitles
Eliminate the tedious task of manual transcription. Hei.io automatically generates time-synced captions and translated subtitles with high accuracy, making your content more accessible and engaging on all platforms. You can easily edit the text and timing before exporting the final files.
