Abstract: The described examples provide for a sound recognition and notification process and apparatus that provides a notification to a hearing impaired person via a portable device in response to the recognition of a selected sound. A processor of the sound notification apparatus is configured to compare the detected sound data to a model for recognition. If the sound data matches the model, features are extracted from the detected sound data and used by the processor to generate reference data, e.g. an updated sound model. The reference is retained in a memory of the apparatus to facilitate subsequent sound recognition without having to rely upon an external device for analysis. Recognition of a sound, based on a substantial match to stored reference data, may trigger transmission of a notification message indicating an occurrence of the corresponding sound.

Additionally, sound fields are analyzed to detect gestural input and trigger associated programmatic actions.
