Abstract

A method for operating a hearing prosthesis is provided. A plurality of settings are provided, each setting providing a different operating functionality for the hearing prosthesis suitable for different situations. A signal analysis is executed on input signals to the hearing prosthesis. The signal analysis monitors characteristics of a current situation to detect any change and, in the case of detecting change, classifies the current situation into one of a plurality of predefined states. The suitability of the settings is compared with the determined state. One or more optimal choice(s) of setting(s) is identified for the current situation. The one or more optimal choice(s) of setting(s) is presented to a user. The user is then allowed to make a selection from the presented choice(s) of setting(s). If a selection is received from the user, the selected setting is executed. A hearing prosthesis is also provided.
