text: Whenever huge amounts of XML data have to be transferred from a web server
to multiple clients, the transferred data volumes can be reduced significantly
by sending compressed XML instead of plain XML. Whenever applications require
querying a compressed XML format and XML compression or decompression time is
a bottleneck, parallel XML compression and parallel decompression may be of significant
advantage. We choose the XML compressor XSDS as starting point for our new approach
to parallel compression and parallel decompression of XML documents for the following
reasons. First, XSDS generally reaches stronger compression ratios than other
compressors like gzip, bzip2, and XMill. Second, in contrast to these compressors,
XSDS not only supports XPath queries on compressed XML data, but also XPath queries
can be evaluated on XSDS compressed data even faster than on uncompressed XML.
We propose a String-search-based parsing approach to parallelize XML compression
with XSDS, and we show that we can speed-up the compression of XML documents by
a factor of 1.4 and that we can speed-up the decompression time even by a factor
of up to 7 on a quad-core processor.

text: The accuracy of automatic speech recognition systems in noisy and reverberant
environments can be improved notably by exploiting the uncertainty of the estimated
speech features using so-called uncertainty-of-observation techniques. In this
paper, we introduce a new Bayesian decision rule that can serve as a mathematical
framework from which both known and new uncertainty-of-observation techniques
can be either derived or approximated. The new decision rule in its direct form
leads to the new significance decoding approach for Gaussian mixture models, which
results in better performance compared to standard uncertainty-of-observation
techniques in different additive and convolutive noise scenarios.

text: In this contribution we derive the Maximum A-Posteriori (MAP) estimates of
the parameters of a Gaussian Mixture Model (GMM) in the presence of noisy observations.
We assume the distortion to be white Gaussian noise of known mean and variance.
An approximate conjugate prior of the GMM parameters is derived allowing for a
computationally efficient implementation in a sequential estimation framework.
Simulations on artificially generated data demonstrate the superiority of the
proposed method compared to the Maximum Likelihood technique and to the ordinary
MAP approach, whose estimates are corrected by the known statistics of the distortion
in a straightforward manner.

text: In this paper we present an improved version of the recently proposed Maximum
A-Posteriori (MAP) based noise power spectral density estimator. An empirical
bias compensation and bandwidth adjustment reduce bias and variance of the noise
variance estimates. The main advantage of the MAP-based postprocessor is its low
estimation variance. The estimator is employed in the second stage of a two-stage
single-channel speech enhancement system, where eight different state-of-the-art
noise tracking algorithms were tested in the first stage. While the postprocessor
hardly affects the results in stationary noise scenarios, it becomes the more
effective the more nonstationary the noise is. The proposed postprocessor was
able to improve all systems in babble noise w.r.t. the perceptual evaluation of
speech quality performance.

text: Among the different configurations of multi-microphone systems, e.g., in applications
of speech dereverberation or denoising, we consider the case without a priori
information of the microphone-array geometry. This naturally invokes explicit
or implicit identification of source-receiver transfer functions as an indirect
description of the microphone-array configuration. However, this blind channel
identification (BCI) has been difficult due to the lack of unique identifiability
in the presence of observation noise or near-common channel zeros. In this paper,
we study the implicit BCI performance of blind signal enhancement techniques such
as the adaptive principal component analysis (PCA) or the iterative blind equalization
and channel identification (BENCH). To this end, we make use of a recently proposed
metric, the normalized filter-projection misalignment (NFPM), which is tailored
for BCI evaluation in ill-conditioned (e.g., noisy) scenarios. The resulting understanding
of implicit BCI performance can help to judge the behavior of multi-microphone
speech enhancement systems and the suitability of implicit BCI to serve channel-based
(i.e., channel-informed) enhancement.

text: In this paper, we consider the Maximum Likelihood (ML) estimation of the parameters
of a GAUSSIAN in the presence of censored, i.e., clipped data. We show that the
resulting Expectation Maximization (EM) algorithm delivers virtually biasfree
and efficient estimates, and we discuss its convergence properties. We also discuss
optimal classification in the presence of censored data. Censored data are frequently
encountered in wireless LAN positioning systems based on the fingerprinting method
employing signal strength measurements, due to the limited sensitivity of the
portable devices. Experiments both on simulated and real-world data demonstrate
the effectiveness of the proposed algorithms.

text: Recently, substantial progress has been made in the field of reverberant speech
signal processing, including both single- and multichannel de-reverberation techniques,
and automatic speech recognition (ASR) techniques robust to reverberation. To
evaluate state-of-the-art algorithms and obtain new insights regarding potential
future research directions, we propose a common evaluation framework including
datasets, tasks, and evaluation metrics for both speech enhancement and ASR techniques.
The proposed framework will be used as a common basis for the REVERB (REverberant
Voice Enhancement and Recognition Benchmark) challenge. This paper describes the
rationale behind the challenge, and provides a detailed description of the evaluation
framework and benchmark results.

text: In this contribution we extend a previously proposed Bayesian approach for
the enhancement of reverberant logarithmic mel power spectral coefficients for
robust automatic speech recognition to the additional compensation of background
noise. A recently proposed observation model is employed whose time-variant observation
error statistics are obtained as a side product of the inference of the a posteriori
probability density function of the clean speech feature vectors. Further a reduction
of the computational effort and the memory requirements are achieved by using
a recursive formulation of the observation model. The performance of the proposed
algorithms is first experimentally studied on a connected digits recognition task
with artificially created noisy reverberant data. It is shown that the use of
the time-variant observation error model leads to a significant error rate reduction
at low signal-to-noise ratios compared to a time-invariant model. Further experiments
were conducted on a 5000 word task recorded in a reverberant and noisy environment.
A significant word error rate reduction was obtained demonstrating the effectiveness
of the approach on real-world data.

text: 'We present a novel method to exploit correlations of adjacent time-frequency
(TF)-slots for a sparseness-based blind speech separation (BSS) system. Usually,
these correlations are exploited by some heuristic smoothing techniques in the
post-processing of the estimated soft TF masks. We propose a different approach:
Based on our previous work with one-dimensional (1D)-hidden Markov models (HMMs)
along the time axis we extend the modeling to two-dimensional (2D)-HMMs to exploit
both temporal and spectral correlations in the speech signal. Based on the principles
of turbo decoding we solved the complex inference of 2D-HMMs by a modified forward-backward
algorithm which operates alternatingly along the time and the frequency axis.
Extrinsic information is exchanged between these steps such that increasingly
better soft time-frequency masks are obtained, leading to improved speech separation
performance in highly reverberant recording conditions.'

text: In this paper we present a speech presence probability (SPP) estimation algorithmwhich
exploits both temporal and spectral correlations of speech. To this end, the SPP
estimation is formulated as the posterior probability estimation of the states
of a two-dimensional (2D) Hidden Markov Model (HMM). We derive an iterative algorithm
to decode the 2D-HMM which is based on the turbo principle. The experimental results
show that indeed the SPP estimates improve from iteration to iteration, and further
clearly outperform another state-of-the-art SPP estimation algorithm.

text: In this paper we consider the unsupervised word discovery from phonetic input.
We employ a word segmentation algorithm which simultaneously develops a lexicon,
i.e., the transcription of a word in terms of a phone sequence, learns a n-gram
language model describing word and word sequence probabilities, and carries out
the segmentation itself. The underlying statistical model is that of a Pitman-Yor
process, a concept known from Bayesian non-parametrics, which allows for an a
priori unknown and unlimited number of different words. Using a hierarchy of Pitman-Yor
processes, language models of different order can be employed and nesting it with
another hierarchy of Pitman-Yor processes on the phone level allows for backing
off unknown word unigrams by phone m-grams. We present results on a large-vocabulary
task, assuming an error-free phone sequence is given. We finish by discussing
options how to cope with noisy phone sequences.

text: In this paper we present a novel initialization method for unsupervised learning
of acoustic patterns in recordings of continuous speech. The pattern discovery
task is solved by dynamic time warping whose performance we improve by a smart
starting point selection. This enables a more accurate discovery of patterns compared
to conventional approaches. After graph-based clustering the patterns are employed
for training hidden Markov models for an unsupervised speech acquisition. By iterating
between model training and decoding in an EM-like framework the word accuracy
is continuously improved. On the TIDIGITS corpus we achieve a word error rate
of about 13 percent by the proposed unsupervised pattern discovery approach, which
neither assumes knowledge of the acoustic units nor of the labels of the training
data.
