Legacy TTS Sounds Flat, Rigid, and Robotic
Traditional text-to-speech engines flatten sentences into uniform pitch contours, stripping the warmth, breath rhythms, and micro-pauses that make human voice captivating. Long-form narrations drift into monotonous droning, and non-Latin conjuncts stutter into phonetic chaos.
Acoustic Pillars of Ultra-Realistic Speech
Modulate vocal delivery from calm corporate narrations to dramatic readings with natural vocal fry, laughter, and breath intervals.
Full support for W3C-compliant PLS dictionaries and inline International Phonetic Alphabet (IPA) tags for complex brand names and medical jargon.
Multi-speaker engine tracks character dialogue across 500+ page manuscripts with zero timbre drift or energy decay.
Stream audio chunks as fast as LLMs produce tokens. First-chunk playback begins in the listener's ear before sentence two generates.
Four Steps to Studio-Quality Synthesis
From plaintext script or real-time LLM token streams to uncompressed 48kHz studio audio.
Draft or Stream Your Script
Submit raw text, SSML tags, or stream tokens directly via WebSocket from Claude or GPT-4o.
Select Voice & Calibrate Prosody
Choose from curated studio voices or custom clones. Tune stability, similarity boost, and style exaggeration.
Phonetic G2P & Conjunct Disambiguation
Neural acoustic model disambiguates complex conjuncts and matches contextual phonetic stress.
Instant Lossless 48kHz Stream
Receive uncompressed 48kHz WAV or MP3 audio chunks signed with an indelible cryptographic watermark.
Audio Showcase & Voice Library Samples
Listen to raw studio exports synthesized with Zunn Sono across genres, accents, and emotional deliveries. Zero post-processing, zero artificial enhancements.
Voice AI API, SDKs & WebSockets
Official SDKs for Python, Node.js, and Next.js. Bi-directional WebSockets for real-time streaming, comprehensive webhooks, and predictable per-character pricing.
Instant Voice Cloning & Custom Voice AI
Replicate authentic vocal timbre, accent, and emotional resonance for personal agents or custom brand identities. Backed by mandatory voice captcha verification and neural watermarking.
