Vehicle Ambient Audio Classification Via Neural Network Machine Learning
First Claim
1. A method, comprising:
- receiving audible information from one or more microphones;
receiving vehicle information of one or more conditions of a vehicle from one or more sensors;
determining whether the vehicle is at risk of theft or whether an occupant of the vehicle is at risk of danger based on the vehicle information and the audible information; and
triggering one or more actions upon determining that the occupant or the vehicle is at risk.

Abstract
A method and an apparatus for detecting and classifying sounds around a vehicle via neural network machine learning are described. The method involves an audio recognition system that may determine the origin of the sounds being inside or outside of a vehicle and classify the sounds into different categories such as adult, child, or animal sounds. The audio recognition system may communicate with a plurality of sensors in and around the vehicle to obtain information of conditions of the vehicle. Based on information of the sounds and conditions of the vehicles, the audio recognition system may determine whether an occupant or the vehicle is at risk and send alert messages or issue warning signals.

13. An apparatus implemented as an audio recognition system of a vehicle, comprising:
-
one or more microphones configured to detect a plurality of sounds; one or more sensors configured to monitor one or more conditions of the vehicle; a memory configured to store raw data of the sounds and a plurality of audio files recorded from the sounds; a processor configured to perform operations comprising; recording the sounds in the memory as the audio files; processing the audio files with a mel-frequency cepstrum algorithm by calculating a respective set of mel-frequency cepstrum coefficients for each of the audio files; and receiving information of the one or more conditions of the vehicle from the sensors; a first neural network comprising at least a first hidden layer with a first set of nodes; and a second neural network comprising at least a second hidden layer with a second set of nodes. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
