It’s been five months since I released Pocket TTS for Unity and I just pushed my newest packages for Qwen3 TTS and OmniVoice TTS. Both of these are built specifically for Windows desktop projects running fully local, giving you high-end offline speech without the cloud API headaches.
If you need deep creative control over character voices, Qwen3 TTS is the one to pick. It has a more focused language selection, but it lets you design unique voices directly using natural language prompts and fine-tune emotional delivery for narrative-heavy games or editor tools. On the other hand, if your project needs massive global reach, OmniVoice TTS brings ridiculous coverage with support for over 600 languages out of the box, along with fast zero-shot voice cloning and expressive tags like laughter.
