What Dia TTS Voice Changer is
Dia TTS Voice Changer converts speech in an existing recording into a different voice using AI. This browser-based tool accepts uploaded audio, so you do not need to retype or transcribe the words. Choose a built-in voice or upload a reference recording, then preview the converted result in your browser and download it. Source audio can be MP3, OGG, WAV, M4A or AAC, up to 50MB and 10 minutes; reference audio supports the same formats up to 10MB and 60 seconds. The editor estimates use at 5 credits per minute. New users can sign up for complimentary credits, but there is no free plan. Paid plans start at $7.90/mo (annual). Basic lists 12,000 credits per year and standard support; Pro lists 26,400 and priority support; Ultra lists 54,000 and VIP support. The service processes uploaded files, not live microphone, gaming, phone-call or Discord audio. Results vary with recording clarity, background noise, speaking style and target voice; an exact match is not guaranteed. Use only a voice you own or have permission to reference.
