Nova-Vox

What Nova-Vox is

Nova-Vox is a free, open-source vocal synthesizer for Windows that combines traditional methods with AI-driven techniques. Its ESPER framework handles audio descriptions and supports both concatenative and granular synthesis, while also providing a basis for AI systems. A Voicebank can place expressions, pitches, custom AI models, and settings together in one file. The engine automatically selects a pitch for each note, and expressions can be specified with a single letter. The maker describes its phonetics system as supporting any language and includes a node editor for building adaptive post-processing effects. The Nova-Vox 1.0 download includes the Development Kit and AI base models for creating Voicebanks; the homepage offers a Windows installer. Commercial use is allowed. The maker identifies Johannes Klatt as maintainer and lead developer. It also notes that version 1.0 has performance problems, a very large installation, and code issues. The planned successor, Mirai, has no release date. Its proposed features include cross-language synthesis, an improved editor, a WebUI Development Kit, audio tracks, and VST support.
