About the Company

Lucida AI

Real-time speech-to-speech language coaching platform

Lucida AI is a London-based platform that enables real-time speech-to-speech practice for language coaching and global communication. It serves both consumers and enterprises with real-time pronunciation and fluency feedback during spoken practice. The product works by analyzing spoken input from a user, providing immediate feedback through its proprietary Speech Language Model infrastructure, and guiding users through practice to improve pronunciation and fluency across multiple languages. The company differentiates itself with a dedicated focus on speech-to-speech coaching (not just text-based feedback), real-time evaluation, and a scalable enterprise deployment path, supported by an expanding language base and geographic reach. Its goal is to grow its language coverage and geographic availability while deploying its technology at scale to millions of users and across business customers.
