"The Meta AI service on AI Glasses stores text transcripts and audio recordings of your voice interactions by default to help improve Meta's products. This includes improving the Meta AI service (and related technologies), and training and improving our speech technologies... We use machine learning and trained reviewers to process this data to improve, troubleshoot and train our products."
Meta uses voice recordings, transcripts, photos, and videos from AI Glasses to train AI models by default, including human review of voice interactions, with opt-out rather than opt-in for the AI service on glasses.
