The system can also support the use of personal devices including wearables in order to deliver private personalized messages discreetly. For example, one embodiment of a public announcement system gathers and aggregates demographic data of a population in a public place. The public announcement system creates inferences from this data to predict content delivery preferences, such as a sequence of languages or delivery characteristics (e.g., speech rate, content and volume). The delivery preferences can be ranked and then a recommendation for a public announcement provided."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems, methods and devices for public announcements","description":"A public addressing system can identify user preferences including language, volume, and method of delivery to provide improved content in a given geographical area using perceptual computing techniqu","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9705618","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
