TDNavigator — Voice co-pilot for truck drivers

TDNavigator is a landscape tablet co-pilot for truck drivers. The driver holds one button, then talks. AssemblyAI's Voice Agent listens, reasons, and speaks on one connection: speech to text, the model, and the spoken reply. There is no second voice engine. The driver can ask what the weather is ahead, how far the next stop is, where the nearest diesel is, how many drive hours are left, and what the route is. The agent answers in one to three short sentences, and only from the tool results. If it does not have the fact, it says so. The driver can interrupt, and it stops talking. Those tools cover weather, distance, nearby fuel, hours of service, and the current route. The public demo at tdnav.com uses a simulated truck position and a simulated hours clock, so a judge can try it without a truck. It is not a certified electronic logging device. The voice layer is MIT licensed, with unit tests. The live demo is https://tdnav.com/?demo=1. Hold the Navigator button and allow the microphone.
