Abstract (en)
[origin: EP0865026A2] The modification method has an analogue speech signal converted into a corresponding digital signal. The digital signal is entered in a memory, with lengthening or shortening of the signal by a pre-defined factor, using an add overlap method. The stored speech signal is divided into segments which are weighted via a window function with a first rising section, a constant section and a falling section. There is a comparison made of the weighted segments, for waveform similarity and addition of the segments, when the similarity has a maximum value.
