Abstract :
Gabor type of analytic filters are used together with Teager-Kaiser energy operator based DESA-1 and two other algorithms to study pitch-synchronous modulation effects in speech. The methods are tested with synthetic and natural speech. Common problems and limitations of these methods are discussed.
