Yiperi Voice | Stylized Speech Engine

Yiperi Voice is a lightweight dialogue voice engine for Unity. It turns written text into a predictable sequence speech sounds, giving characters a simple voice-like cadence without full voice acting, cloud TTS, or heavy dialogue systems.

Designed for cartoon, retro, comedy, RPG, creature, NPC, or UI dialogue. This is not a full dialogue manager and not a resources intensive realistic text-to-speech.

Features:

• 12 built-in voice banks authored at home: Cartoon, retro, robotic, whisper, keyboard, mosquito, zombie, and metallic-style voices.
• Offline real-time playback: Plays through a normal Unity AudioSource.
• Text analysis into words, tokens, pauses, and stress markers.
• Word callbacks for syncing text reveal with speech.
• Token and viseme callbacks for custom animation or effects.
• Language definition files based on editable JSON.
• Supports adding custom voice banks by recording up to 68 phonetic tokens.
• Includes demo scenes for dialogue, minimal setup, and voice/language showcase.

Current language support: English-en, Spanish-es, Japanese-ja, Polish-pl, Thai-th, Arabic-ar, French-fr, Korean-ko, Portuguese-pt, Turkish-tr, Czech-cz, Hindi-hi, Dutch-nl, Russian-ru, Yiperi-yiperi, German-de, Italian-it, Norwegian-no, Swedish-sv, Chinese-zh

Language support means broad approximations designed for stylized cartoon speech, not exact linguistic pronunciation. For native writing systems where pronunciation cannot be reliably guessed, Yiperi supports [display<>say] syntax, so your UI can show native text while the engine reads a pronunciation-friendly version.

Included demos:

• Demo-1-Dialog: animated character dialogue showcase.
• Demo-2-minimal: minimal script setup.
• Demo-3-Voices: voice and language showcase.

Additional notes:

• Text Mesh Pro Essentials may be required to view UI text in the demo scenes.
• Python scripts are avaiable to help building custom voice banks.
