Your voice, in Yeonhong
Voice Studio is now open in beta. Upload your recordings and we’ll build a TTS voice from your voice. If you like it, sign a contract and we’ll release it as a Studio Yeonhong TTS voice. Everyone whose voice is released gets Plus Membership.
Since this is a beta, the screens and process may change. We’ll let you know through our news and announcements if they do.
How it works
- 1. Apply: Sign in with your Google account and enter the voice name you want, the feel of the voice, and your recording setup.You’ll also enter your name, date of birth, and mobile number.
- 2. Agree and record: After checking the required consents, read the passages on screen aloud and record them.You can record right in your browser or upload files you’ve recorded (WAV, MP3, M4A, FLAC).
- 3. Pick a candidate: Once you submit, we build several candidate voices from your recordings. Listen to each one, or type your own sentence to hear it.You can keep refining a candidate you like (Enhance) or start over (Create new). You can create up to 5 times a day.
- 4. Verification recording: After you confirm a candidate, record one more short sentence so we can confirm it’s really you.
