A Python server backend for a 'digital life' voice assistant that combines speech recognition, ChatGPT-based conversation, sentiment analysis, and neural TTS (VITS). It communicates over the network with a separate Unreal Engine client that renders an animated character, records audio, and plays responses.

Use cases

• build a talking virtual avatar with speech recognition and synthesis
• run a ChatGPT-powered voice assistant with a 3D character frontend
• self-host an ASR + LLM + TTS pipeline in Python
• create an animated digital human that responds to voice in real time
• experiment with VITS text-to-speech and sentiment-aware chatbots

When to choose

• you want a complete open-source voice assistant backend with ASR, LLM, and TTS wired together
• you already use or plan to use the companion Unreal Engine client for character rendering
• you have an NVIDIA GPU (or accept slower CPU inference) and want a self-hosted setup

When to avoid

• you need a polished end-user application rather than a server component requiring manual model downloads and builds
• you need cloud-scale or multi-user production deployment
• you cannot obtain the required models or lack a compatible GPU/CPU setup
