Time-domain harmonic scaling

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].
