A rhythm dictionary storage section stores a rhythm dictionary table which associates the contents of a control of an apparatus with a registered rhythm pattern. The registered rhythm pattern is obtained by typifying a pronunciation pattern of a name indicating the contents of the control. A control section analyzes the electrical signal from the rhythm input section to recognize the input rhythm pattern input by the user, recognizes the contents of a corresponding control by referencing the rhythm dictionary storage section, and controls an operation of an in-vehicle apparatus.

Abstract: Provided are apparatus and method for processing bell sound in a wireless terminal. Position data of sound source samples corresponding to bell sound contents are extracted in advance and then replayed. In the apparatus for processing bell sound, musical score data are parsed from bell sound contents, and position data of sound source samples corresponding to the parsed musical score data are extracted, then establishing a database. By repeatedly using the position data of the sound source samples corresponding to the musical score data to be used one or more times, it is unnecessary to perform the process of repeatedly parsing the sound source so as to read the sound source position information during the real-time replay of the bell sound, resulting in reduction of the system load.
