A simple new procedure called STRAIGHT (speech transformation and representation using
adaptive interpolation of weighted spectrum) has been developed. STRAIGHT uses pitch-
adaptive spectral analysis combined with a surface reconstruction method in the time-
frequency region, and an excitation source design based on phase manipulation. It
preserves the bilinear surface in the time-frequency region and allows for over 600%
manipulation of such speech parameters as pitch, vocal tract length, and speaking rate …
