Dia TTS Voice Changer review
A paid web tool for converting recordings with built-in or reference voices.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Dia TTS Voice Changer converts recorded speech into another voice through a web browser. It offers built-in target voices, reference-audio conversion, and speech-to-speech processing for existing recordings. Users can upload audio, preview generated results, and download converted files. The product fits creators, educators, and teams producing voiceovers, podcasts, training content, and creative prototypes. Reference recordings can be used for authorized custom voice conversion.
Pricing is organized across Basic, Pro, and Ultra plans, with monthly and annual billing. Basic costs $9.90 per month monthly or $7.90 per month annually, and includes high-quality audio outputs plus standard customer support. Pro costs $19.90 monthly or $15.90 per month annually, adding priority customer support while retaining high-quality audio outputs. Ultra costs $36.90 monthly or $29.90 per month annually, with VIP customer support and the same listed output quality. The published plans do not include a permanent $0 option, so ongoing access requires a paid subscription.
The standout fit is recorded-audio conversion with broad source-format support and generous per-file limits. MP3, OGG, WAV, M4A, and AAC files are accepted, with uploads up to 50 MB and 10 minutes. Browser previews make it possible to review generated audio before downloading it. The trade-off is a narrow platform footprint: the service is available on the web, and the listed plans emphasize support tiers rather than distinct feature packages. Choose Dia TTS Voice Changer if you need browser-based conversion for existing recordings and value larger upload limits; choose an alternative if you need a permanent free plan, non-web platform access, or clearly differentiated paid features.
