What Dia TTS Voice Changer is
Dia TTS Voice Changer is a browser-based service that converts speech in an existing recording into another voice using AI. Users can choose a built-in target voice or upload a reference recording, without retyping or transcribing the source words. Source audio accepts MP3, OGG, WAV, M4A, and AAC files up to 50MB and 10 minutes. Reference recordings use those formats up to 10MB and 60 seconds. The editor estimates five credits per minute. Converted audio can be previewed in a browser and downloaded. This is file processing, not a real-time microphone, gaming, phone-call, or Discord changer. Results can vary with clarity, background noise, speaking style, and target voice, and an exact match is not guaranteed. New users receive complimentary trial credits.
