Raspberry Pi Based In-Car AI Translation Device

Project Title Raspberry Pi Based In-Car AI Translation Device Project Description I am looking for an experienced Rasp Pi and Embedded Systems developer to build the first working prototype of an in-car AI translation device. The goal is to allow passengers and drivers who speak different languages to communicate naturally in real time. System Overview Passenger Side: * 5–7 inch touchscreen mounted behind the front seat * Language selection * Speak button * Translation display * Passenger microphone * Passenger speaker Driver Side: * Bluetooth AirPods or Bluetooth earbud (preferred) * Optional small speaker * Driver selects native language once using a simple control button Processing Unit: * Raspberry Pi 5 (8GB) Internet: * Dedicated in-car Wi-Fi hotspot (T-Mobile or similar) Translation: * Cloud-based translation using Google, OpenAI, DeepL, or similar services Communication Flow Passenger speaks → Speech recognition → Translation → Driver hears translated speech in AirPods Driver responds → Speech recognition → Translation → Passenger hears translated speech through speaker and sees translated text on screen Current Goal This is NOT a mass-production project yet. The objective is to build a working prototype that can be installed and tested in a real Uber vehicle. Skills Required * Raspberry Pi 5 * Python * Embedded Linux * Bluetooth Audio * Touchscreen UI * Speech Recognition * Translation APIs * Text-to-Speech * Audio Device Integration Deliverables * Complete Raspberry Pi setup * Software architecture * Working touchscreen interface * Bluetooth audio integration * Translation workflow * Source code * Installation instructions * Functional prototype ready for real-world testing Questions for Applicants 1. Have you previously built Raspberry Pi touchscreen products? 2. Have you worked with speech recognition or translation systems? 3. What architecture would you recommend for this project? 4. What is your estimated budget and timeline? 5. Can you show similar projects you have completed? Important I am looking for a practical engineer who can help build a reliable real-world prototype, not just create UI mockups or concept designs
