  text: The standard approach of job search engines disregards the structural aspect
    of job announcements in the Web. Bag-of-words indexing leads to a high amount
    of noise. In this paper we describe a method that uses local grammars to transform
    unstructured Web pages into structured forms. Evaluation experiments show high
    efficiency of information access to the generated documents.

  text: 'The term uncertainty decoding has been phrased for a class of robustness
    enhancing algorithms in automatic speech recognition that replace point estimates
    and plug-in rules by posterior densities and optimal decision rules. While uncertainty
    can be incorporated in the model domain, in the feature domain, or even in both,
    we concentrate here on feature domain approaches as they tend to be computationally
    less demanding. We derive optimal decision rules in the presence of uncertain
    observations and discuss simplifications which result in computationally efficient
    realizations. The usefulness of the presented statistical framework is then exemplified
    for two types of realworld problems: The first is improving the robustness of
    speech recognition towards incomplete or corrupted feature vectors due to a lossy
    communication link between the speech capturing front end and the backend recognition
    engine. And the second is the well-known and extensively studied issue of improving
    the robustness of the recognizer towards environmental noise.'

  text: In distributed and network speech recognition the actual recognition task
    is not carried out on the user{\rq}s terminal but rather on a remote server in
    the network. While there are good reasons for doing so, a disadvantage of this
    client-server architecture is clearly that the communication medium may introduce
    errors, which then impairs speech recognition accuracy. Even sophisticated channel
    coding cannot completely prevent the occurrence of residual bit errors in the
    case of temporarily adverse channel conditions, and in packet-oriented transmission
    packets of data may arrive too late for the given real-time constraints and have
    to be declared lost. The goal of error concealment is to reduce the detrimental
    effect that such errors may induce on the recipient of the transmitted speech
    signal by exploiting residual redundancy in the bit stream at the source coder
    output. In classical speech transmission a human is the recipient, and erroneous
    data are reconstructed so as to reduce the subjectively annoying effect of corrupted
    bits or lost packets. Here, however, a statistical classifier is at the receiving
    end, which can benefit from knowledge about the quality of the reconstruction.
    In this book chapter we show how the classical Bayesian decision rule needs to
    be modified to account for uncertain features, and illustrate how the required
    feature posterior density can be estimated in the case of distributed speech recognition.
    Some other techniques for error concealment can be related to this approach. Experimental
    results are given for both a small and a medium vocabulary recognition task and
    both for a channel exhibiting bit errors and a packet erasure channel.

  text: In this paper, we derive an uncertainty decoding rule for automatic speech
    recognition (ASR), which accounts for both corrupted observations and inter-frame
    correlation. The conditional independence assumption, prevalent in hidden Markov
    model-based ASR, is relaxed to obtain a clean speech posterior that is conditioned
    on the complete observed feature vector sequence. This is a more informative posterior
    than one conditioned only on the current observation. The novel decoding is used
    to obtain a transmission-error robust remote ASR system, where the speech capturing
    unit is connected to the decoder via an error-prone communication network. We
    show how the clean speech posterior can be computed for communication links being
    characterized by either bit errors or packet loss. Recognition results are presented
    for both distributed and network speech recognition, where in the latter case
    common voice-over-IP codecs are employed.

  text: This paper addresses the robustness of automatic speech recognition to environmental
    noise. In order to account for reliability of the clean feature estimate we employ
    the feature posterior density conditioned on observed noisy features to perform
    uncertainty decoding. We investigate two approaches to estimate the posterior
    using a discrete feature space, first conditioning only on the current observation,
    and second on the whole feature sequence of an utterance. Experiments with Aurora
    2 showed that the latter provides slightly better performance, as it allows for
    exploiting the temporal correlations between consecutive features.

  text: This paper considers the convolutive blind source separation of speech sources
    in the presence of spatially correlated noise. We introduce a method for estimating
    the scaled mixing matrix from the sources to the microphones even if coherent
    noise is present. This is achieved by combining time-frequency sparseness with
    the generalized eigenvalue decomposition of the power spectral density matrix
    (PSD) of the noisy speech and noise-only microphone signals. Separation is performed
    by spatial filtering with coefficients constructed by Gram-Schmidt orthogonalization
    which places spatial nulls at the interferer{^A}?`s direction. Experimental results
    show that our approach is capable of separating 2 sources in a reverberant environment
    (RT60=0ms..500ms) degraded by significant directional noise.

  text: This Paper deals with a new Technique for multi-channel separation of speech
    signals from convolutive mixtures under coherent noise. We demonstrate how the
    scaled transfer functions from the sources to the microphones can be estimated
    even in the presence of stationary coherent noise. The key to this are generalized
    eigenvalue decompositions of the power spectral density (PSD) matrices of the
    noisy speech and noise-only microphone signals with a controlled estimation of
    these matrices exploiting time-frequency sparseness of the speech sources. Separation
    is further improved by subsequent Gram-Schmidt orthogonalization which places
    spatial nulls at the interferers{\rq} directions, while noise reduction is improved
    by employing a novel blocking matrix and adaptive interference canceller in a
    Generalized Sidelobe Canceller (GSC)-like structure. We report promising experimental
    results for 2 speech sources with significant coherent noise in reverberant environments
    (RT60=0oms..500ms).

  text: The generalized sidelobe canceller by Griffith and Jim is a robust beamforming
    method to enhance a desired (speech) signal in the presence of stationary noise.
    Its performance depends to a high degree on the construction of the blocking matrix
    which produces noise reference signals for the subsequent adaptive interference
    canceller. Especially in reverberated environments the beamformer may suffer from
    signal leakage and reduced noise suppression. In this paper a new blocking matrix
    is proposed. It is based on a generalized eigenvalue problem whose solution provides
    an indirect estimation of the transfer functions from the source to the sensors.
    The quality of the new generalized eigenvector blocking matrix is studied in simulated
    rooms with different reverberation times and is compared to alternatives proposed
    in the literature.

  text: In this paper a switching linear dynamical model (SLDM) approach for speech
    feature enhancement is improved by employing more accurate models for the dynamics
    of speech and noise. The model of the clean speech feature trajectory is improved
    by augmenting the state vector to capture information derived from the delta features.
    Further a hidden noise state variable is introduced to obtain a more elaborated
    model for the noise dynamics. Approximate Bayesian inference in the SLDM is carried
    out by a bank of extended Kalman filters, whose outputs are combined according
    to the a posteriori probability of the individual state models. Experimental results
    on the AURORA2 database show improved recognition accuracy.

  text: 'In this paper, the noise estimation for model-based speech feature enhancement
    in automatic speech recognition (ASR) is investigated. Beside a stationary noise
    prior, three linear state space models for the (cepstral) noise process are considered.
    We have derived novel EM algorithms for the estimation of the noise model parameters:
    A blockwise EM algorithm is applied on noise-only input data. It is supposed to
    be used during the offline training mode of the recognizer. Further a sequential
    online EM algorithm is employed to adapt the observation variance in recognition
    mode which works as well under the asumption of a stationary noise prior and a
    linear state model for the noise. Experiments on the AURORA4 database lead to
    improved recognition results with the new state model compared to the assumption
    of stationary noise.'
