[{"abstract":[{"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.

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."}],"publication":"21th European Signal Processing Conference (EUSIPCO 2013)","citation":{"mla":"Tran Vu, Dang Hai, and Reinhold Haeb-Umbach. “Blind Speech Separation Exploiting Temporal and Spectral Correlations Using Turbo Decoding of 2D-HMMs.” <i>21th European Signal Processing Conference (EUSIPCO 2013)</i>, 2013.","ama":"Tran Vu DH, Haeb-Umbach R.

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."}]},{"oa":"1","department":[{"_id":"54"}],"type":"conference","date_created":"2019-07-12T05:30:53Z","related_material":{"link":[{"relation":"supplementary_material","url":"https://groups.uni-paderborn.de/nt/pubs/2013/WaKoHaRa13_Award.pdf","description":"Award"},{"description":"Poster","url":"https://groups.uni-paderborn.de/nt/pubs/2013/WaKoHaRa13_Poster.pdf","relation":"supplementary_material"}]},"citation":{"mla":"Walter, Oliver, et al. “Hierarchical System for Word Discovery Exploiting DTW-Based Initialization.” <i>Automatic Speech Recognition and Understanding Workshop (ASRU 2013)</i>, 2013.","ama":"Walter O, Korthals T, Haeb-Umbach R, Raj B.

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.","lang":"eng"}],"citation":{"ieee":"O.

The origin of errors in temporal judgments is a question older than experimental psychology itself. One of the earliest suspects is attention. According to the concept of prior entry, attention accelerates attended stimuli; thus they have “prior entry” to perceptive processing stages, including consciousness. Although latency advantages for attended stimuli have been revealed in psychophysical studies many times, these measures (e.g. temporal order judgments, simultaneity judgments) cannot test the prior-entry hypothesis completely. Since they assess latency differences between an attended and an unattended stimulus, they cannot distinguish between faster processing of attended stimuli and slower processing of unattended stimuli. Therefore, we present a novel paradigm providing separate estimates for processing advantages respectively disadvantages of attended and unattended stimuli. We found that deceleration of unattended stimuli contributes more strongly to the prior-entry illusion than acceleration of attended stimuli. Thus, in the temporal domain, attention fulfills its selective function primarily by deceleration of unattended stimuli. That means it is actually posterior entry, not prior entry which accounts for the largest part of the effect."}],"publication":"PLoS ONE","department":[{"_id":"424"}],"type":"journal_article","date_created":"2021-12-13T10:02:05Z","intvolume":"         8","publication_status":"published","date_updated":"2022-06-07T00:13:12Z","publication_identifier":{"issn":["1932-6203"]},"author":[{"last_name":"Weiß","first_name":"Katharina","full_name":"Weiß, Katharina"},{"full_name":"Hilkenmeier, Frederic","last_name":"Hilkenmeier","first_name":"Frederic"},{"last_name":"Scharlau","first_name":"Ingrid","orcid":"0000-0003-2364-9489","full_name":"Scharlau, Ingrid","id":"451"}],"year":"2013","title":"Attention and the Speed of Information Processing: Posterior Entry for Unattended Stimuli Instead of Prior Entry for Attended Stimuli","doi":"10.1371/journal.pone.0054257","language":[{"iso":"eng"}],"article_number":"e54257","main_file_link":[{"url":"https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0054257","open_access":"1"}],"citation":{"apa":"Weiß, K., Hilkenmeier, F., &#38; Scharlau, I.

Since the states of the HMM represent the potential user locations, their number determines the quantization error introduced by discretizing the allowable user positions through the use of the HMM. To reduce this quantization error we introduce â??pseudoâ?? states, whose emission probability, which models the RSSI measurements at this location, is synthesized from those of the neighboring states of which a Gaussian emission probability has been estimated during the training phase. The experimental results demonstrate the effectiveness of this approach. By introducing on average two pseudo states per original HMM state the positioning error could be significantly reduced without increasing the training effort."}],"date_created":"2019-07-12T05:28:50Z","department":[{"_id":"54"}],"oa":"1","type":"conference"},{"date_updated":"2024-02-20T14:49:00Z","publication_status":"published","title":"Zeitgenössische Praktiken von Subjektivierung.
