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.
