Abstract

The spectrogram is a well-studied time–frequency representation, but there are numerous others. There has been a rich literature on this subject, and many different time–frequency representations have been devised, studied, and applied to various signal analysis problems (e.g. [1]). Unfortunately, the subject has never to my knowledge been made accessible to speech scientists, with the result that we have rarely availed ourselves of any such representations other than the spectrogram. This chapter is an attempt to rectify this situation somewhat, although the presentation takes on a more advanced mathematical character at certain points.
