AI/ML Developer (Speech AI)
Company Background Our client is a technology startup building advanced voice automation solutions for the quick-service restaurant industry. The company develops a privacy-conscious, high-performance drive-thru voice assistant that automates real-time customer interactions, improves order accuracy, and helps restaurant chains increase revenue and operational efficiency. Its product is designed for fast deployment in noisy, high-volume drive-thru environments and is already gaining market traction through cooperation with a major restaurant chain. Project Description The project is a next-generation voice automation engine for drive-thru order-taking in quick-service restaurants. It enables fully automated, real-time conversations between customers and the restaurant ordering system using modern speech recognition, natural language processing, and text-to-speech technologies. The engineer will work on improving the core voice and audio capabilities of the platform, including Speech-to-Text, Text-to-Speech, noise cancellation, speech enhancement, and real-time audio pipelines. The main focus will be on reducing latency, improving recognition quality and speech clarity, and making the system robust in extremely noisy real-world environments such as drive-thrus.
