I’m building SpeakVR, a Unity-based VR experience that lets users chat naturally with an AI companion. The focus is casual conversation, so the assistant must answer general questions, engage in small talk, correct a user’s grammar when needed, and slip into light role-play (for instance, pretending to be a customer in a practice scenario). My foundation is in place: a simple VR scene, OpenAI keys and usage rights, plus the intention to rely on Whisper for speech recognition, ChatGPT for dialogue, and a lifelike text-to-speech engine for the final voice reply. What’s missing is the glue that turns these pieces into a seamless, low-latency conversational loop. Here’s what I need from you: • C# scripts that capture microphone input inside Unity, stream it to Whisper, and return clean transcriptions • Prompt-building logic that feeds context-aware text to ChatGPT and receives a coherent reply that can include gentle grammar corrections • Integration of a high-quality TTS service, with spatialised playback in the VR scene so the voice feels present • Simple inspector fields for API keys, temperature, and prompt tweaks, along with a toggle for on-screen captions • A small demo scene showing everything working end to end, plus clear comments and a short README so I can extend the project myself Efficiency matters; the interaction needs to feel fluid, not laggy. If you know your way around asynchronous calls (UniTask, coroutines, or similar) and are comfortable optimising network traffic, let’s talk.
