Smart Mouth Billy Bass is an offline, LAN-only voice assistant built into a Big Mouth Billy Bass novelty toy, using an ESP32-S3 for audio capture, motor control, and playback, with a GPU backend handling whisper.cpp STT, llama.cpp LLM, and Kokoro TTS. The project is notable for its complete vertical integration—custom PCB, firmware with wake-word detection, a protocol shim, and a sentence-streaming design that pipelines TTS with LLM generation for low time-to-first-audio.
Target audience: embedded developers, hobbyists, AI/ML engineers
