Time-domain harmonic scaling (THDS) is a method for time-scale modification of speech (or other audio signals)[1], allowing the apparent rate of speech articulation to be changed without affecting the pitch-contour and the time-evolution of the formant structure[2]. THDS differs from other time-scale modification algorithms in that time-scaling operations are performed in the time domain (not the frequency domain)[3]. .
History
proposed by D. Malah in 1979[4]
