Gaubitch ND, Habets E, Naylor PA, 2008, Multimicrophone speech dereverberation using spatiotemporal and spectral processing, Pages: 3222-3225-3222-3225

Speech signals acquired in a reverberant room with microphones positioned at a distance from the talker are degraded in quality due to reverberation and measurement noise. Therefore, enhancement of reverberant speech is important in hands-free teleco.....

Conference paper

Khong AWH, Lin X, Naylor PA, 2008, Algorithms for identifying clusters of near-common zeros in multichannel blind system identification and equalization, Pages: 389-392-389-392

Blind system identification (BSI) and equalization algorithms have been applied to multichannel systems with high order such as found in acoustic impulse responses. Studies on the performance of such algorithms in the presence of near-common zeros ha.....

Conference paper

Wen Y-CJ, Habets E, Naylor PA, 2008, Blind estimation of reverberation time based on the distribution of signal decay rates, Pages: 329-332-329-332

The reverberation time is one of the most prominent acoustic characteristics of an enclosure. Its value can be used to predict speech intelligibility, and is used by speech enhancement techniques to suppress reverberation. The reverberation time is u.....

Conference paper

Khong AWH, Lin X, Doroslovacki M, Naylor PAet al., 2008, Frequency domain selective tap adaptive algorithms for sparse system identification, Pages: 229-232-229-232

We propose a new low complexity and fast converging frequency-domain adaptive algorithm for sparse system identification. This is achieved by exploiting the MMax and SP tap-selection criteria for complexity reduction and fast convergence respectively.....

Conference paper

Khong AWH, Gan W-S, Naylor PA, Brookes DMet al., 2008, A low complexity fast converging partial update adaptive algorithm employing variable step-size for acoustic echo cancellation, Pages: 237-240-237-240

Partial update adaptive algorithms have been proposed as a means of reducing complexity for adaptive filtering. The MMax tap-selection is one of the most popular tap-selection algorithms. It is well known that the performance of such partial update a.....

Conference paper

Habets E, Gaubitch ND, Naylor PA, 2008, Temporal selective dereverberation of noisy speech using one microphone, Pages: 4577-4580-4577-4580

Reverberant speech can be described as sounding distant with noticeable coloration and echo. These detrimental perceptual effects are caused by early and late reflections, respectively, and reduces the fidelity and intelligibility of speech. It is we.....

Conference paper

Zhang W, Gaubitch ND, Naylor PA, 2008, Computationally efficient equalization of room impulse responses robust to system estimation errors, Pages: 4025-4028-4025-4028

Equalization techniques for room impulse responses (RIRs) are important in acoustic signal processing applications such as speech dereverberation. In practice, only approximate estimates of the RIRs are available and the inverse filters designed from.....

The DYPSA algorithm detects glottal closure instants (GCI) in speech signals. We present an improvement in the algorithm in which a voiced/unvoiced/silence discrimination measure is applied in order to reduce the spurious GCIs detected incorrectly fo.....
