Abstract
The invention relates to a cellular phone terminal system, and in particular to a method for changing timbre of a voice signal during conversation in a cellular phone terminal system having a filter for filtering a PCM input signal. The method comprises the steps of: waiting for a timbre selector key input for a desired timbre when a timbre converter key is inputted during conversation; and setting a filter coefficient of the filter correspondingly to the timbre selector key input and filtering the PCM signal to change timbre.
Claims8
A method for changing timbre of a cellular telephone terminal having a filter for filtering an input signal, said method comprising the steps of:
- waiting for a timbre selector key input for a desired timbre when a timbre converter key is inputted during conversation;
- and
- setting a filter coefficient of the filter corresponding to the timbre selector key input and filtering the input signal to change timbre.
A method for changing timbre of a cellular telephone terminal having a filter for filtering a PCM input signal, said method comprising the steps of:
- matching each of filter coefficients of the filter corresponding to each of a number of timbres to change the PCM signal into the number of timbres;
- determining if a timbre converter key is inputted during conversation when conversation starts after said matching of the filter coefficients;
- waiting for a timbre selector key input for a desired timbre when a timbre converter key is inputted;
- detecting a filter coefficient set to the inputted timbre selector key;
- controlling the filter to filter the PCM signal with the detected filter coefficient;
- and
- changing timbre.
