SOUND EVENT DETECTION

摘要

A system and method for the use of sensors and processors of existing, distributed systems, operating individually or in cooperation with other systems, networks or cloud-based services to enhance the detection and classification of sound events in an environment (e.g., a home), while having low computational complexity. The system and method provides functions where the most relevant features that help in discriminating sounds are extracted from an audio signal and then classified depending on whether the extracted features correspond to a sound event that should result in a communication to a user. Threshold values and other variables can be determined by training on audio signals of known sounds in defined environments, and implemented to distinguish human and pet sounds from other sounds, and compensate for variations in the magnitude of the audio signal, different sizes and reverberation characteristics of the environment, and variations in microphone responses.

主权项

1. An environmental data monitoring and reporting system, comprising:
a device sensor that detects sound in an area and generates an audio signal based on the detected sound; a device processor communicatively coupled to the device sensor, wherein the processor is configured to convert the audio signal received from the device sensor into low-resolution audio signal data and analyze the audio signal data, at the device processor level, to identify the detected sound as an area human or pet occupancy-related sound and provide a communication regarding the detected occupancy-related sound; and a device communication interface communicatively coupled to the device processor, wherein the communication interface is configured to send the communication regarding the detected occupancy-related sound, wherein the device sensor, device processor and device communication interface are integrated into a single premises management device.
