Taigi AI Voice Conversion
White Palace Building 6F, 1-4-10 Higashi, Kunitachi, Tokyo
What it is
Taigi AI Voice Conversion is a free web tool that changes uploaded source audio to resemble an uploaded target voice sample. You provide both files by selecting them or using drag and drop. The product page says it supports all languages, and the FAQ lists WAV, MP3, and M4A formats. Conversion runs on uploaded files rather than in real time, and results are intended for demo review. Taigi AI Labs recommends short, clear source and target recordings with little background noise and similar volume levels. The maker describes connecting voice reading, speech recognition, translation, and dialogue in workflows for learning materials, subtitles, field notes, and business proof-of-concept review. API integration is available for its speech synthesis functionality, with businesses directed to contact Taigi AI Labs about requirements. The company says data provided to its services will not be used for AI training. Taigi AI Labs LLC operates the service from Kunitachi, Tokyo.
