The record

What it does: The browser-based voice changer converts speech in an existing recording to a different voice using AI.
Target voice options: Users can choose a built-in voice or upload a reference recording as the target voice.
Speech-to-speech workflow: The tool converts recorded speech without requiring users to retype or transcribe its words.
Audio formats and limits: Source audio supports MP3, OGG, WAV, M4A, and AAC up to 50MB and 10 minutes; reference audio supports the same formats up to 10MB and 60 seconds.
Credit estimate: The editor estimates usage at 5 credits per minute.
Try it for free: The page says new users can sign up for complimentary credits to try the service.
Output: Users can preview the converted result in their browser and download the generated audio.
Not real time: The tool processes uploaded audio files and is not a real-time microphone, gaming, phone-call, or Discord voice changer.
Result variability: Results may vary with recording clarity, background noise, speaking style, and target voice, and an exact voice match is not guaranteed.
Intended users: The maker describes creators, educators, and teams as users, with examples including voiceovers, podcasts, training materials, and character prototypes.
Voice permissions: The maker says to upload only your own voice or a voice you have explicit permission to use as a reference.
Security statement: The privacy policy states that it uses TLS 1.3 for data in transit and AES-256 encryption for data at rest.
Support: The site lists email contact at [email protected] and its plans specify standard, priority, or VIP customer support.
Project affiliation: The site says Dia TTS is an independent project and is not affiliated with, endorsed by, or connected to Nari Labs.
Price from: $0.66/mo
