Abstract (en)
The invention allows to controllably modify a value of a characteristic, such as an age, associated to a sound contained in sound data (30) such as voice to which is associated a sampling frequency, the sound exhibiting a given value (A) of the characteristic for a first sampling frequency F1. This is achieved by : producing from the sound data at least one sound data portion (UD) containing a sound portion to be reproduced with a modified value of the characteristic, the sound data portion having a first sampling duration R1 at the first sampling frequency F1, establishing (36, 44-48) a second frequency F2 selected as a function of a desired modification in the value of the characteristic, time adjusting (38) the sound data portion (UD) by elaborating a time-adjusted form (UDta) thereof on the basis of a sampling frequency equal to the second frequency F2, the time-adjusting step at least partially tending to cause the sampling duration of the time-adjusted form of sound data portion at the second frequency F2 to match the first sampling duration R1, and playing the time adjusted sound data portion (UDta). Preferably, the time-adjusting step is performed by means of a Pitch-Synchronous Overlap and Add (PSOLA) algorithm (38) or the like. <IMAGE>
