ViiTor TTS enables voice cloning, speech editing, and expressive synthesis in a single model. Modify only the parts you want, preserve speaker identity and emotion, and generate natural speech with low-latency inference.
ViiTor TTS is designed for high-quality voice production. It can clone a voice from reference audio and generate natural, fluent, ready-to-use speech from text. Unlike basic text-to-speech systems, ViiTor TTS focuses on naturalness, expressive details, and editability. It aims not only to make generated speech sound similar to a speaker, but also to preserve speaking style, tone, pauses, and emotional nuance. In real production workflows, users often need to adjust a sentence, a phrase, or a subtle tone. ViiTor TTS supports local segment regeneration, allowing users to refine pronunciation, tone, or content without recreating the entire audio.
A model stack for voice cloning, speech generation, and audio refinement, making AI speech more natural, stable, and controllable.
Clone voice tone, style, and expressive details from reference audio for dubbing, character voices, and branded voice assets.
Generate natural speech from text for voiceovers, narration, courses, audio content, and batch production.
Understand not only what is said, but also tone, pauses, speaking rhythm, and conversational expression.
Emotion and Paralinguistic Control
Supports the generation of tone, pauses, emotional intensity, and non-verbal expressions, making the voice more realistic and expressive.
Partial Editable Generation
Supports semantic-level segment regeneration, enabling precise modification of local pronunciation and expression without the need for overall rework.
Text-Free Voice Cloning
High-consistency timbre reproduction can be completed without reference text, supporting cross-language and arbitrary text input
Extreme Speed Non-AR Inference Architecture
Optimized based on the Non-Autoregressive architecture, 5-second audio can be generated within 100ms, with an inference speed of up to 40x Real-time.
From short-form voiceovers to branded voice assets, help creators and teams generate publishable and reusable speech content faster.
Developers can access ViiTor TTS through APIs, including reference audio upload, voice extraction, text-to-speech generation, expressive control, local regeneration, and fast batch speech generation.
