A text-to-speech library mod for Lethal Company that integrates the lightweight, local Piper TTS engine. This library makes it easy for devs to add TTS speech to their mods, with generation happening fully offline on the player's machine.
All players in the lobby must have
TTS-Companyinstalled. Players missing the mod will not hear any generated text-to-speech audio.
Marked as
AI-Generatedcause of the AI TTS it produces.
- Provides a API for other mods to generate local, low-latency text-to-speech audio.
- Spawns, manages, and prepares the underlying background Piper process so it's ready to handle audio requests.
- Uses the Piper TTS engine to generate text-to-speech directly on your machine without relying on external web APIs.
- Caches generated voice lines to significantly cut down on processing overhead and maximize in-game performance for recurring phrases.
- Gives developers the ability to pre-generate specific text-to-speech audio lines ahead of time to guarantee instant and seamless playback when needed.
- Does nothing on its own: It solely initializes the background process and exposes the code API. It will not add chat commands, voice lines, or gameplay features unless paired with a mod that uses this library.
- Does not send any data to external servers: all audio synthesis is completely offline.
