  abstract = {Speech recognition systems for languages with a rich inflectional morphology (like German) suffer from the limitations of a word--based full--form lexicon. Although the morphological and acoustical knowledge about words is coded implicitly within the lexicon entries (which are usually closely related to the orthography of the language at hand) this knowledge is usually not explicitly available for other tasks (e.g. detecting OOV words, prosodic analysis). This paper presents an HMM--based `word' recognizer that uses morpheme--like units on the string level for recognizing spontaneous German conversational speech (Verbmobil corpus). The system has no explicit word knowledge but uses a morpheme--bigram to capture the German word and sentence structure to some extent. The morpheme recognizer is tightly coupled with a prosodic classifier in order to compensate for some of the additional ambiguity introduced by using morphemes instead of words.}

  abstract = {This article describes how the performance of a Dutch continuous speech recognizer was improved by modeling pronunciation variation. We propose a general procedure for modeling pronunciation variation. In short, it consists of adding pronunciation variants to the lexicon, retraining phone models and using language models to which the pronunciation variants have been added. First, within-word pronunciation variants were generated by applying a set of five optional phonological rules to the words in the baseline lexicon. Next, a limited number of cross-word processes were modeled, using two different methods. In the first approach, cross-word processes were modeled by directly adding the cross-word variants to the lexicon, and in the second approach this was done by using multi-words. Finally, the combination of the within-word method with the two cross-word methods was tested. The word error rate (WER) measured for the baseline system was 12.75\%. Compared to the baseline, a small but statistically significant improvement of 0.68\% in WER was measured for the within-word method, whereas both cross-word methods in isolation led to small, non-signicant improvements. The combination of the within-word method and cross-word method 2 led to the best result: an absolute improvement of 1.12\% in WER was found compared to the baseline, which is a relative improvement of 8.8\% in WER.},

  title = {Characterization of Speakers for Improved Automatic Speech Recognition},
  abstract = {Automatic speech recognition technology is becoming increasingly widespread in many applications. For dictation tasks, where a single talker is to use the system for long periods of time, the high recognition accuracies obtained are in part due to the user performing a lengthy enrolment procedure to tune the parameters of the recogniser to their particular voice characteristics and speaking style. Interactive speech systems, where the speaker is using the system for only a short period of time (for example to obtain information) do not have the luxury of long enrolments and have to adapt rapidly to new speakers and speaking styles. This thesis discusses the variations between speakers and speaking styles which result in decreased recognition performance when there is a mismatch between the talker and the systems models. An unsupervised method to rapidly identify and normalise differences in vocal tract length is presented and shown to give improvements in recognition accuracy for little computational overhead. Two unsupervised methods of identifying speakers with similar speaking styles are also presented. The first, a data-driven technique, is shown to accurately classify British and American accented speech, and is also used to improve recognition accuracy by clustering groups of similar talkers. The second uses the phonotactic information available within pronunciation dictionaries to model British and American accented speech. This model is then used to rapidly and accurately classify speakers.},

  abstract = {In this paper, we present a novel, efficient search strategy for large vocabulary continuous speech recognition. The search algorithm, based on a stack decoder framework, utilizes phone-level posterior probability estimates (produced by a connectionist/HMM acoustic model) as a basis for phone deactivation pruning - a highly efficient method of reducing the required computation. The single-pass algorithm is naturally factored into the time-asynchronous processing of the word sequence and the time-synchronous processing of the HMM state sequence. This enables the search to be decoupled from the language model while still maintaining the computational benefits of time-synchronous processing. The incorporation of the language model in the search is discussed and computationally cheap approximations to the full language model are introduced. Experiments were performed on the North American Business News task using a 60,000 word vocabulary and a trigram language model. Results indicate that the computational cost of the search may be reduced by more than a factor of 40 with a relative search error of less than 2\% using the techniques discussed in the paper.},

  abstract = {In this paper we introduce a set of related confidence measures for large vocabulary continuous speech recognition (LVCSR) based on local phone posterior probability estimates output by an acceptor HMM acoustic model. In addition to their computational efficiency, these confidence measures are attractive as they may be applied at the state-, phone-, word- or utterance-levels, potentially enabling discrimination between different causes of low confidence recognizer output, such as unclear acoustics or mismatched pronunciation models. We have evaluated these confidence measures for utterance verification using a number of different metrics. Experiments reveal several trends in `profitability of rejection', as measured by the unconditional error rate of a hypothesis test. These trends suggest that crude pronunciation models can mask the relatively subtle reductions in confidence caused by out-of-vocabulary (OOV) words and disfluencies, but not the gross model mismatches elicited by non-speech sounds. The observation that a purely acoustic confidence measure can provide improved performance over a measure based upon both acoustic and language model information for data drawn from the Broadcast News corpus, but not for data drawn from the North American Business News corpus suggests that the quality of model fit offered by a trigram language model is reduced for Broadcast News data. We also argue that acoustic confidence measures may be used to inform the search for improved pronunciation models.},

We investigated to what extent the degree of agreement between the listeners and the CSR was affected by employing various sets of phone models (PMs). Overall, the PMs perform more similarly to the listeners when pronunciation variation is modeled. However, the various sets of PMs lead to different results for insertion and deletion processes. Furthermore, we found that to a certain degree, word error rates can be used to predict which set of PMs to use in the transcription tool.},

  abstract = {The paper describes the speech to speech translation system INTARC, developed during the first phase of the Verbmobil project. The general design goals of the INTARC system architecture were time synchronous processing as well as incrementality and interactivity as a means to achieve a higher degree of robustness and scalability. Interactivity means that in addition to the bottom-up (in terms of processing levels) data flow the ability to process top-down restrictions considering the same signal segment for all processing levels. The construction of INTARC 2.0, which has been operational since fall 1996, followed an engineering approach focussing on the integration of symbolic (linguistic) and stochastic (recognition) techniques which led to a generalization of the concept of a ``one pass'' beam search.}

  abstract = {This paper describes an approach for constructing a mixture of language models based on simple statistical notions of semantics using probabilistic models developed for information retrieval. The approach encapsulates corpus-derived semantic information and is able to model varying styles of text. Using such information, the corpus texts are clustered in an unsupervised manner and a mixture of topic-specific language models is automatically created. The principal contribution of this work is to characterise the document space resulting from information retrieval techniques and to demonstrate the approach for mixture language modelling. A comparison is made between manual and automatic clustering in order to elucidate how the global content information is expressed in the space. We also compare (in terms of association with manual clustering and language modelling accuracy) alternative term-weighting schemes and the effect of singular valued decomposition dimension reduction (latent semantic analysis). Test set perplexity results using the British National Corpus indicate that the approach can improve the potential of statistical language modelling. Using an adaptive procedure, the conventional model may be tuned to track text data with a slight increase in computational cost.},

Detailed evaluation is performed using a similar North American Broadcast News system, to take advantage of the TREC SDR evaluation methodology. We report results on this evaluation, with particular reference to the effect of query expansion and of automatic segmentation algorithms.},

These models can be used for automatic speech recognition and to give insights into articulatory behaviour. They belong to a class of continuous-state Markov models, which we believe can offer improved performance over conventional Hidden Markov Models (HMMs) by better accounting for the continuous nature of the underlying speech production process -- that is, the movements of the articulators. To assess the performance of our models, a simple speech recognition task was used, on which the models show promising results.},

The other (referred to as SPRACH-R) is a rule-based system which uses matching against stored name lists, part-of-speech tagging, and light phrasal parsing with specialised named entity grammars. We provide an overview of the two approaches and present results on the Hub-4E IE-NE evaluation task.},
