PURPOSE: An apparatus and a method for changing text/speech using phoneme environment and mute section are provided to improve clearness and nature of compound sound by using mute period length information for selecting the compound unit. CONSTITUTION: The apparatus for changing text/speech using phoneme environment and mute section includes following units. A language processing unit(21) extracts phoneme stream and sentence structure information from the text being inputted. A rhythm processing unit(22) receives the phoneme stream and sentence structure information and estimates a rhythm control parameter value by using a rule and rhythm table. A compound unit database(24) stores sound pieces corresponding to the searching information of compound unit. A signal processing unit(23) produces a compound unit searching information, selects the stored candidate sound pieces and then produces a desired compound sound by compounding the selected sound pieces.
