KNOWLEDGE & ARCHITECTURE
Frequently Asked Questions
Everything you need to know about Crematic's on-device neural voice studio, acoustic synthesis, and audio privacy.
What is Crematic AI Voice Studio?
Crematic is a professional, creative audio instrument and neural text-to-speech synthesizer. Unlike legacy cloud APIs that introduce network lag and monthly subscription limits, Crematic runs state-of-the-art neural acoustic models directly inside your browser via WebAssembly SIMD, delivering zero-latency vocal synthesis with studio fidelity.
Does Crematic send my text or voice recordings to external servers?
Never. Crematic features a 100% on-device architecture. Once model weights are cached in your browser’s local storage, all acoustic inference, phoneme generation, and audio rendering occur completely offline on your device’s processor. Your sensitive scripts, book chapters, or character dialogues remain strictly confidential.
How many AI voices are included in the roster?
Crematic includes all 54 studio-grade neural voices across 9 language and dialect families: 20 US English voices (11 Female, 9 Male), 8 UK English voices (4 Female, 4 Male), 8 Mandarin Chinese voices, 5 Japanese voices, 4 Hindi voices, 3 Spanish voices, 3 Brazilian Portuguese voices, 2 Italian voices, and 1 French voice. Each voice features distinct vocal resonance, cadence, and emotive range suitable for audiobooks, video narrations, gaming characters, and podcasting.
Can I use the synthesized audio for commercial projects and YouTube?
Yes! You retain full ownership of the exported WAV and audio files you create in Crematic. You can monetize them in YouTube videos, client presentations, video games, commercials, podcasts, and audiobooks, in full accordance with our Terms of Service and Acceptable Use Policy.
Why is on-device neural TTS better than cloud TTS?
On-device neural TTS eliminates cloud server latency (0ms network roundtrips), prevents costly per-character API billing, works without an internet connection once loaded, and eliminates data leak risks. It turns your browser into an independent, self-contained creative audio workstation.
Which web browsers are supported?
Crematic supports all modern evergreen browsers that support WebAssembly SIMD and Web Audio API, including Google Chrome, Apple Safari (macOS & iOS), Microsoft Edge, Brave, and Mozilla Firefox on desktop, laptop, and modern tablet devices.
