Lucas and Luna explore how on-device AI is enabling real-time sign language translation on smartphones. They dive into the technical challenges of capturing hand shapes, movement, and facial expressions simultaneously using the phone's camera and a lightweight neural network running entirely on the device. The episode focuses on a specific case: a 2025 research paper from Carnegie Mellon that achieved 93% accuracy on a 1,000-sign vocabulary without any cloud dependency. They discuss how models are compressed to fit under 100 MB, the role of Apple's Neural Engine and Google's Tensor Processing Unit, and why latency under 300 milliseconds is critical for natural conversation. The hosts also touch on current app examples like Google's Live Transcribe and Apple's SignTime, and where the technology still struggles — like regional dialect signs and two-handed gestures. A concrete, technical look at a rapidly maturing accessibility feature.
