abstract = {An improvement of the classical single-channel speech enhancement
technique by comb filtering is presented in the paper. The comb filter is adaptive and
tuned by the estimated pitch frequency. It is constructed empirically in the frequency
domain using two approaches and is applied in voiced frames only also in frequency
domain. The pitch frequency is estimated from enhanced speech in the frequency
domain too. As classical speech enhancement technique, which is used prior comb
filtering, the minimum mean-square error log-spectral amplitude estimator was
applied. The obtained enhancement of speech corrupted by different noise sources is
evaluated and compared for configuration with and without comb filtering by
informal listening tests and using signal-to-noise ratio.},
