VoxTTS Online sells prepaid Khmer text-to-speech API tokens for developers, creators, dubbing tools, and automation systems.
Users generate Khmer speech, session clone voice, and batch audio from the web dashboard or authenticated API endpoints.
KHQRcc ABA Pay QR is active for automatic checkout and callback verification.
Users pay with ABA Mobile or a KHQR-supported bank app. Credits are added after KHQRcc payment confirmation is verified.
Creator is 10,000 tokens for $1.50 and Pro is 30,000 tokens for $4.00. Larger add-on packs are available on Billing.
The checkout creates a fresh exact-amount QR for the selected pack.
The app verifies KHQRcc signature, amount, currency, order status, and duplicate transaction data.
After approval, the system adds credits once and updates billing, dashboard balance, API limits, and payment history.
Simple, transparent prepaid token packs. Scale with API keys and batch voice cloning workloads.
