Locally periodic signals, such as voiced sounds and sounds of musical instruments, play important roles in our everyday life. Physical characteristics of such sounds are temporally varying and usually analyzed using short term Fourier transform. However, temporally varying components which are dependent on relative location of the windowing function to the analyzed signals, caused difficulties in signal processing applications. An interpretation of the role of this periodicity as a systematic mechanism for sampling underlying system characteristics led to temporally static representations of periodic signals and provided a basis for flexible manipulation of speech sounds. |
