What you can expect

As an Audio AI Engineer, you will research and develop algorithms for accent conversion, voice conversion, speech synthesis, and speech recognition on low-latency streaming architectures. You’ll prototype and refine end-to-end audio models that enhance intelligibility and naturalness while maintaining speaker identity. Working closely with product and platform teams, you’ll help bring these models into real-time communication systems. You will also evaluate and optimize model performance across dimensions such as quality, latency, and scalability. Staying current with advances in speech processing, you’ll contribute to innovation through patents and internal knowledge sharing.
