Intelligent Situational Awareness: A Semantically Aware Audio Agent for Personalized Noise Management
This invention is an intelligent audio agent designed to work with acoustic devices like headphones to provide selective, user-programmable situational awareness. It allows users to maintain high-quality active noise cancellation while delegating specific listening tasks to an AI that alerts them only to personally relevant ambient sounds.
Description
The technology functions as a personalized auditory filter by utilizing an artificial intelligence (AI) agent, often based on a large language model (LLM), to monitor a user’s environment in real-time. Users provide natural language commands—either through speech or text—to define specific "acoustic events of interest," such as an emergency siren, a specific keyword, or a particular person's voice. The AI agent then analyzes the request to generate a task description and automatically synthesizes a customized processing pipeline by selecting the most appropriate models from a library of available tools. When the system detects a target sound within the ambient audio stream, it can trigger various types of alerts, including voice notifications, haptic feedback, or text outputs. For devices using active noise cancellation (ANC), the system can intelligently "pass through" only the relevant sounds, ensuring the user remains aware of critical information without being overwhelmed by general background noise. The system is versatile, employing different strategies such as keyword spotting for speech tasks or feature extraction and classification for emergency alerts.Applications
- Consumer Electronics: Integration into wireless earbuds, headphones, and smart wearable devices to enhance user safety and convenience.- Workplace Safety: Specialized headsets for industrial or construction environments that filter loud noise but alert workers to specific alarms or spoken warnings.
- Assistive Technologies: Devices for individuals with hearing impairments that can translate specific environmental sounds into haptic or visual alerts.
- Smart Home Systems: Ambient monitoring systems that can notify users of specific domestic sounds (e.g., a baby crying or a doorbell) while they are wearing headphones.
- Public Safety and First Responders: Communication gear that allows personnel to focus on critical voice transmissions while remaining aware of specific environmental hazards.
Advantages
- Customizable Awareness: Enables users to delegate specific listening tasks via natural language, creating a personalized auditory environment.- Enhanced Noise Management: Maintains the benefits of active noise cancellation for irrelevant sounds while ensuring important alerts are never missed.
- Intelligent Task Synthesis: Automatically selects and configures the best AI models to match the user's specific request in real-time.
- Diverse Alerting Mechanisms: Supports multiple notification types, including haptic feedback, voice outputs, and selective audio pass-through.
- Multimodal Processing: Capable of handling a wide range of tasks, from spotting specific keywords to identifying complex environmental sounds like sirens.
