Method and System for Diagnosing Mechanical Problems Using Mobile Audio Capture and Analytics
When a problem with a vehicle (e.g., electrical, mechanical, etc.) is intermittent, a mechanic can have difficulty identifying the exact problem, especially when the problem is not occurring at the moment the mechanic is evaluating the vehicle.

To assist in diagnosing the problem, mechanics often ask owners to describe any unusual noises that occur while the vehicle is in operation. In addition, a driver that is less sensitive to automotive sounds might not hear the trouble as a mechanic can; thus, a problem can remain undetected by the vehicle owner.

A method or system is needed to assist both vehicle owners and mechanics in identifying a problem with the vehicle

based on unusual sounds during operation.

The novel contribution is a method and system for diagnosing mechanical problems in a vehicle using mobile audio capture and analytics. The system runs on a mobile device such as a smart phone. It captures audio through the device's microphone while the user is in the vehicle. It records the sounds of the engine and other mechanical parts of the car. It can simply record these sounds for playback to a mechanic, or recognize the sounds as symptomatic of specific mechanical problems and alert the driver to these problems.

The system consists of modules for Capture and Recording, Recognition, Alert, and Playback.

The Capture and Recording module operates in one of four modes. In Record mode, it simply records all audio to the device's nonvolatile memory for later playback. In Listen mode, it listens to ambient sounds and sends those sounds to the recognition module. The Listen & Record mode performs both the record function and the listen function. In Standby mode, the system does nothing until triggered by user input (e.g., button press or voice command through the device's voice recognition application), and then switches to one of the three previously listed modes. Recordings require explicit user permission before any recording is done.

The Recognition module receives input from the capture and recording module or the playback module, and then processes those sounds for recognition of mechanical problems using an artifi...
