Research Scientist Intern, Audio Quality with AI in Cambridge

The Meta Reality Labs Research Team brings together a world-class team of researchers, developers, and engineers to create the future of virtual and augmented reality, which together will become as universal and essential as smartphones and personal computers are today. And just as personal computers have done over the past 45 years, AR, VR and MR will ultimately change everything about how we work, play, and connect. We are developing all the technologies needed to enable breakthrough AR glasses and VR headsets, including optics and displays, computer vision, audio, graphics, brain-computer interfaces, haptic interaction, eye/hand/face/body tracking, perception science, and true telepresence. Some of those will advance much faster than others, but they all need to happen to enable AR, VR and MR that are so compelling that they become an integral part of our lives. In particular, the Meta Reality Labs Research audio team is focused on two goals; creating virtual sounds that are perceptually indistinguishable from reality, and redefining human hearing.

These two initiatives will allow us to connect people by allowing them to feel together despite being physically apart, and allow them to converse in even the most difficult listening environments. Meta Reality Labs Research is looking for an intern who is passionate about speech perception and audio quality to investigate why processed speech sometimes sounds degraded or robotic. The project focuses on identifying systematic phonemic errors as causal factors in perceived quality degradation, and linking these errors to human quality and intelligibility judgments. A core method is to explore the capabilities of audio vs video LLMs. This is fundamentally a speech-perception research role; multimodal/LLM methods are a supporting tool rather than the central focus. Our internships are twelve (12) to twenty four (24) weeks long and we have various start dates throughout the year.

Investigate systematic phonemic errors as causal factors in perceived speech quality degradation, and link them to human perceptual judgments.

Build and curate datasets and benchmarks of speech for phoneme-level analysis. Explore and compare the capabilities of audio and video (multimodal) LLMs as tools to support this analysis.

Relate findings to human perceptual data (quality preference and intelligibility) and translate them into actionable insights for research and engineering teams.

Where appropriate, adapt multimodal models to the task in a supporting capacity. Collaborate with researchers, engineers, and cross-functional partners to define goals, communicate findings, and drive improvements in speech quality.

Develop tools and infrastructure to streamline and scale the analysis.

Stay current with research in speech perception and audio quality and intelligibility assessment, and incorporate best practices into Meta's workflows.

Disseminate results through internal reports and presentations, and, when appropriate, external publications.
