“Replicating the subtle friction of the human vocal fold requires a room that is perfectly, terrifyingly silent. We capture the spaces between words.”

1. Class-A Isolated Anechoic Soundstages

Clonecraft operates physical soundstages constructed specifically to eliminate background noise up to -115 dBA. Every wall utilizes composite fiberglass wedges designed to absorb stray sound reflections, resulting in a room reverb time (RT60) below 0.09 seconds. This provides our recording system with clean, uncolored signals directly from the speaker.

2. Vocal Tract Resonance Mapping

Unlike consumer software, our laboratory records the physical anatomy of your voice. Using ultra-sensitive ribbon microphones and high-frequency sensor rings, our engineers map the exact resonance curves of your nasal cavities, chest expansion ratios, and dental alignment variables to capture full somatic voice models.

3. High-Frequency Phonetic Sampling

Our high-fidelity recording protocols utilize massive sample rates. We record vocal tracks using linear PCM 192kHz/32-bit float converters, ensuring that sibilant friction, throat warmth, and soft micro-breaths are resolved without digital compression artifacts.

4. Phoneme Transition Testing (Diphone Accuracy)

Our synthesis models do not reconstruct individual letters; they study phoneme transitions (diphones and triphones). Our laboratory prompts subjects through custom linguistic arrays designed to test how different consonants flow into vowels, securing a natural rhythm and eliminating mechanical staccato sounds.

5. High-Pass Sibilance and Whisper Isolation

A primary indicator of simulated voices is how they handle soft sounds like whispers, breath releases, and high-frequency sibilance. Our labs utilize specialized noise gates to isolate delicate dynamic structures, compiling them into independent layers within the neural modulator model.
