<p>PROBLEM TO BE SOLVED: To provide a method and apparatus for changing sound signals indicating sound data streams having a plurality of syllables. SOLUTION: This method include a step of mapping the sound data streams from the speech signals to tone data streams in accordance with the linguistic rule relating to the syllables and supplying tone signals indicating the tone data streams, a step of supplying carrier signals indicating note strings by forming the note strings meeting the tone signals, a step of supplying the demodulated signals by modulating the carrier signals by the sound signals and a step of supplying the signals which are musically changed in accordance with the linguistic rule and indicate the sound signals. The linguistic rule includes the allocation of the tones to the syllables of the sound data based on the vowels, etc., of the syllables. The musically changed sound signals are usable to indicate incoming telephone calls, etc.</p> |
