An adaptive enhancement procedure is presented which emphasizes continuant spectral features such as formant frequencies, by imposing frequency and amplitude continuity constraints on a short-time Fourier representation of the speech signal. At each point in the time-frequency field, the direction of maximum energy correlation is determined by the angle of(More)
Articial larynxes enable adequate communication for people who are unable to use their larynxes. However, the resulting speech has an unnatural quality and is signicantly less intelligible than normal speech. One of the major problems with the widely-used Transcutaneous Articial Larynx (TAL) is the presence of a steady background noise due to the leakage of(More)
