  text: This paper contains a description of the Philips/RWTH 1998 HUB4 system which
    has been build in a joint e ort of Philips Research Laboratories Aachen and Aachen
    University of Technology. We will focus our discussion on recent improvements
    compared to the original 1997 HUB4 system and evaluate them on the HUB4'97 evaluation
    data. The paper will deal with 1. a rough system overview including feature extraction,
    acoustic training, audio stream segmentation, and decoding 2. log-linear interpolation
    of distance-language models, 3. and the integration of various acoustic and language
    models via Discriminative Model Combination (DMC). The performance of the described
    system is 23% (relative) better than the performance of the 1997 Philips HUB4
    system. A word error rate of 17.9% was achieved on the 1997 HUB4 evaluation set,
    compared to 23.5% using the original 1997 system.

  text: We apply Fisher variate analysis to measure the effectiveness of speaker normalization
    techniques. A trace criterion, which measures the ratio of the variations due
    to different phonemes compared to variations due to different speakers, serves
    as a first assessment of a feature set without the need for recognition experiments.
    By using this measure and by recognition experiments we demonstrate that cepstral
    mean normalization also has a speaker normalization effect, in addition to the
    well-known channel normalization effect. Similarly vocal tract normalization (VTN)
    is shown to remove inter-speaker variability. For VTN we show that normalization
    on a per sentence basis performs better than normalization on a per speaker basis.
    Recognition results are given on Wall Street Journal and Hub-4 databases

  text: 'We examined variants of MFCC and PLP cepstral parameterisations in the context
    of large vocabulary continuous speech recognition under different acous-tical
    environmental conditions: Compared to MFCC, mel-frequency PLP uses a cubic root
    intensity-to-loudness law, and an LPC analysis is applied to the mel-warped spectrum.
    In LPC-smoothed MFCC, the only difference to MFCC is the additional LPC smoothing
    of the warped spectrum. While neither technique was able to significantly outperform
    the MFCC parameterisation in our setup which includes an LDA feature transformation,
    feature set combination via DMC at the acoustic likelihood level and via ROVER
    at the recognized word level delivered small but consistent improvements.'

  text: In transcription of broadcast news, dividing the signal into homogeneous segments,
    and clustering together similar segments is important. Decoding a complete broadcast
    news program in one chunk is technically di cult. Also, through creation of homogeneous
    clusters of segments, improvement from adaptation can be increased. Two systems
    of segmentation and clustering are compared. The best system used the BIC algorithm
    to produce long, homogeneous segments, and a nearest neighbour bottom-up agglomerative
    clustering algorithm to produce homogeneous clusters. Adaptation brought a word
    error rate (WER) improvement from 23:4% to 21:0% using the automatic segmentation
    and clustering, compared to an improvement from 21:8% to 20:0% using a handmade
    \correct" segmentation and clustering.

  text: In this paper the Philips Broadcast News transcription system is described.
    The Broadcast News task aims at the recognition of "found" speech in radio and
    television broadcasts without any additional side information (e.g. speaking style,
    background conditions). The system was derived from the Philips continuous mixture
    density crossword HMM system, using MFCC features and Laplacian densities. A segmentation
    was performed to obtain sentence-like partitions of the broadcasts. Using data-driven
    clustering, the obtained segments were grouped into clusters with similar acoustic
    conditions for adaptation purposes. Gender independent word-internal and crossword
    triphone models were trained on 70 hours of the HUB4 training data. No focus condition
    specific training was applied. Channel and speaker normalization was done by mean
    and variance normalization as well as VTN and MLLR. The transcription was produced
    by an adaptive multiple pass decoder starting with phrase-bigram decoding using
    word-internal triphones and finishing with a phrase-trigram decoding using MLLR-adapted
    crossword models.

  text: 'In this paper we describe some characteristics of the acoustic modeling used
    in the Philips continuous-speech recognition system for the DARPA Hub-4 1997 evaluation,
    which are related to robustness issues. We aimed at a conceptually simple system:
    We trained two model sets on 70 hours of the Hub-4 training data, one for within-word
    and one for cross-word decoding. These model sets were used for both genders and
    all environmental conditions. In order to be able to do so, channel normalization
    (mean, variance normalization) and speaker normalization (vocal tract length normalization,
    realized by an appropriate shift of the center frequencies of the mel filter bank)
    have been applied, as well as adaptation techniques. MLLR-based unsupervised batch
    adaptation on clusters of segments was conducted both after a first within-word
    decoding and a cross-word decoding pass. The training strategy and the effects
    of the various normalization and adaptation techniques will be discussed in the
    paper.'

  text: 'Although speaker normalization is attempted in very different manners, vocal
    tract normalization (VTN) and speaker adaptive training (SAT) share many common
    properties. We show that both lead to more compact representations of the phonetically
    relevant variations of the training data and that both achieve improved error
    rate performance only if a complementary normalization or adaptation operation
    is conducted on the test data. Algorithms for fast test speaker enrollment are
    presented for both normalization methods: in the framework of SAT, a pre-transformation
    step is proposed, which alone, i.e. without subsequent unsupervised MLLR adaption,
    reduces the error rate by almost 10% on the WSJ 5k test sets. For VTN, the use
    of a Gaussian mixture model makes obsolete a first recognition pass to obtain
    a preliminary transcription of the test utterance at hardly and loss in performance.'

  text: Addresses the problem of online, writer-independent, unconstrained handwriting
    recognition. Based on hidden Markov models (HMM), which are successfully employed
    in speech recognition tasks, we focus on representations which address scalability,
    recognition performance and compactness. 'Delayed' features are introduced which
    integrate more global, handwriting specific knowledge into the HMM representation.
    These features lead to larger error-rate reduction than 'delta' features which
    are known from speech recognition and even require fewer additional components.
    Scalability is addressed with a size-independent representation. Compactness is
    achieved with linear discriminant analysis. The representations are discussed
    and the results for a mixed-style word recognition task with vocabularies of 200
    (up to 99% correct words) and 20000 words (up to 88.8% correct words) are given.

  text: This paper reports the design of a command-based speech interface for an answering
    machine or a voice mail system. Automatic speech recognition was integrated in
    order to facilitate the remote control and the retrieval of voice messages from
    any telephone in a speech-only dialogue. The design goal was that consumers would
    perceive the speech interface as a benefit compared with the common touch-tone
    interface. In this paper we will first describe the speech technology underlying
    the system. Then it will be shown how, based on this technology, the user interface
    was designed in a top-down approach. We started with the development of a concept
    and tested it by means of a Wizard-of-Oz simulation. After refining the concept
    in parallel design, it was implemented in a high-fidelity prototype. By means
    of qualitative user testing the design was improved in three iteration steps.
    The achievement of the design goal was finally verified with user tests in two
    countries.

  text: 'The increased popularity of mobile telephony introduces both challenges and
    opportunitites for automatic speech recognition. ASR offers ways to simplify the
    use of mobile phones, notably in hands- and eyes-busy situations. However, the
    acoustic environment can be severely degraded and the wireless network may add
    additional distortions to the speech signal. This paper gives an overview of the
    sources of degradation and attempts to robust speech recognition for mobile communications.
    Emphasis is placed on approaches which are suitable for implementation in mobile
    terminals. Two example applications are described which illustrate the robustness
    issues and design considerations typical of low-cost noisy speech recognition:
    voice-dialling in a GSM phone and hands-free digit recognition in the car.'

  text: The SpeechDat project aims to produce speech databases for all official languages
    of the European Union and some major dialectal variants and minority languages
    resulting in 28 speech databases. They will be recorded over fixed and mobile
    telephone networks. This will provide a realistic basis for training and assessment
    of both isolated and continuous-speech utterances, employing whole-word or subword
    approaches, and thus can be used for developing voice driven teleservices including
    speaker verification. The specification of the databases has been developed jointly,
    and is essentially the same for each language to facilitate dissemination and
    use. There will be a controlled variation among the speakers concerning sex, age,
    dialect, environment of call, etc. The validation of all databases will be carried
    out centrally. The SpeechDat databases will be transferred to ELRA for distribution.
    The next databases to be recorded will cover East European languages.

  text: This paper describes speaker-independent speech recognition experiments concerning
    acoustic front end processing on a speech database that was recorded in 3 different
    cars. We investigate different feature analysis approaches (mel-filter bank, mel-cepstrum,
    perceptually linear predictive coding) and present results with noise compensation
    techniques based on spectral subtraction. Although the methods employed lead to
    considerable error rate reduction the error analysis shows that low signal-to-noise
    ratios are still a problem

  text: The paper describes the design, collection and postprocessing of the French
    SpeechDat corpus FRESCO. Being a database of approximately 35000 utterances recorded
    from 1000 callers over the terrestrial telephone network in France, it comprises
    immediately usable and relevant speech for the initial training and assessment
    of speaker independent phoneme model or word model based speech recognizers, as
    they are employed in automated telephone services. FRESCO is one of the 1000 speaker
    telephone speech databases produced as "case studies" within the European project
    SpeechDat(M).

  text: Clustering techniques have been integrated at different levels into the training
    procedure of a continuous-density hidden Markov model (HMM) speech recognizer.
    These clustering techniques can be used in two ways. First acoustically similar
    states are tied together. It will help to reduce the number of parameters but
    also allow to train otherwise rarely seen states together with more robust ones
    (state-tying). Secondly densities are clustered across states, this reduces the
    number of densities while at the same time keeping the best performances of our
    recognizer (density-clustering). We have applied these techniques both to word-based
    small-vocabulary and phoneme-based large-vocabulary recognition tasks. On the
    WSJ task, we could achieve a reduction of the word error rate by 7%. On the TI/NIST-connected
    digit task, the number of parameters was reduced by a factor 2-3 while keeping
    the same string error rate.

  text: Today speech recognition of a small vocabulary can be realized so cost-effectively
    that the technology can penetrate into consumer electronics. But, as first applications
    that failed on the market show, it is by no means obvious how to incorporate voice
    control in a user interface. This paper addresses the issue of how to design a
    voice control so that the user perceives it as a benefit. User interface guidelines
    that are adapted or specific to voice control are presented. Then the process
    of designing a voice control in the user-centred approach is described. By means
    of two examples, the car stereo and telephone answering machine, it is shown how
    this is turned into practice.
