The network is trained to maximize a likelihood criterion derived from a spatial mixture model of the observations. It is trained from scratch without requiring any parallel data consisting of degraded input and clean training targets. Thus, training can be carried out on real recordings of noisy speech rather than simulated ones. In contrast to previous work on unsupervised training of neural mask estimators, our approach avoids the need for a possibly pre-trained teacher model entirely. We demonstrate the effectiveness of our approach by speech recognition experiments on two different datasets: one mainly deteriorated by noise (CHiME 4) and one by reverberation (REVERB). The results show that the performance of the proposed system is on par with a supervised system using oracle target masks for training and with a system trained using a model-based teacher."}],"has_accepted_license":"1","user_id":"59789","oa":"1","publication":"INTERSPEECH 2019, Graz, Austria","ddc":["000"],"type":"conference"},{"citation":{"short":"L.

First proposed as an iterative algorithm, follow-up works have reformulated it as a recursive least squares algorithm and therefore enabled its use in online applications. For this algorithm, the estimation of the power spectral density (PSD) of the anechoic signal plays an important role and strongly influences its performance. Recently, we showed that using a neural network PSD estimator leads to improved performance for online automatic speech recognition. This, however, comes at a price. To train the network, we require parallel data, i.e., utterances simultaneously available in clean and reverberated form. Here we propose to overcome this limitation by training the network jointly with the acoustic model of the speech recognizer. To be specific, the gradients computed from the cross-entropy loss between the target senone sequence and the acoustic model network output is backpropagated through the complex-valued dereverberation filter estimation to the neural network for PSD estimation. Evaluation on two databases demonstrates improved performance for on-line processing scenarios while imposing fewer requirements on the available training data and thus widening the range of applications."}],"has_accepted_license":"1","title":"Joint Optimization of Neural Network-based WPE Dereverberation and Acoustic Model for Robust Online ASR","file":[{"date_created":"2019-12-17T07:28:06Z","file_id":"15334","content_type":"application/pdf","access_level":"open_access","file_name":"ICASSP_2019_Heymann_Paper.pdf","file_size":199109,"creator":"huesera","date_updated":"2019-12-17T07:28:06Z","relation":"main_file"}],"author":[{"full_name":"Heymann, Jahn","first_name":"Jahn","id":"9168","last_name":"Heymann"},{"last_name":"Drude","id":"11213","full_name":"Drude, Lukas","first_name":"Lukas"},{"last_name":"Haeb-Umbach","id":"242","full_name":"Haeb-Umbach, Reinhold","first_name":"Reinhold"},{"first_name":"Keisuke","full_name":"Kinoshita, Keisuke","last_name":"Kinoshita"},{"full_name":"Nakatani, Tomohiro","first_name":"Tomohiro","last_name":"Nakatani"}]},{"author":[{"first_name":"Lukas","full_name":"Drude, Lukas","id":"11213","last_name":"Drude"},{"last_name":"Haeb-Umbach","id":"242","full_name":"Haeb-Umbach, Reinhold","first_name":"Reinhold"}],"citation":{"ieee":"L.

In this paper, we propose stimulated CTC, which uses stimulated learning to help CTC models learn label dependencies implicitly by using an auxiliary RNN to generate the appropriate stimuli. This stimuli comes in the form of an additional stimulation loss term which encourages the model to learn said label dependencies. The auxiliary network is only used during training and the inference model has the same structure as a standard CTC model. The proposed stimulated CTC model achieves about 35% relative character error rate improvements on a synthetic gesture keyboard recognition task and over 30% relative word error rate improvements on the Librispeech automatic speech recognition tasks over a baseline model trained with CTC only.","lang":"eng"}],"has_accepted_license":"1","publication":"ICASSP 2019, Brighton, UK","ddc":["000"],"type":"conference","citation":{"ama":"Heymann J, Khe Chai Sim BL.

However, there has been a longstanding debate whether enhancement should also be carried out on the ASR training data. In an extensive experimental evaluation on the acoustically very challenging CHiME-5 dinner party data we show that: (i) cleaning up the training data can lead to substantial error rate reductions, and (ii) enhancement in training is advisable as long as enhancement in test is at least as strong as in training. This approach stands in contrast and delivers larger gains than the common strategy reported in the literature to augment the training database with additional artificially degraded speech. Together with an acoustic model topology consisting of initial CNN layers followed by factorized TDNN layers we achieve with 41.6% and 43.2% WER on the DEV and EVAL test sets, respectively, a new single-system state-of-the-art result on the CHiME-5 data.

Over the last years, many popular RDF knowledge graphs have grown so large that rankings for the facts they contain cannot be computed directly using the currently common 64-bit platforms. In this paper, we tackle two problems:\r\nComputing ranks on such large knowledge bases efficiently and incrementally. First, we present D-HARE, a distributed approach for computing ranks on very large knowledge graphs. D-HARE assumes the random surfer model and relies on data partitioning to compute matrix multiplications and transpositions on disk for matrices of arbitrary size. Moreover, the data partitioning underlying D-HARE allows the execution of most of its steps in parallel.\r\nAs very large knowledge graphs are often updated periodically, we tackle the incremental computation of ranks on large knowledge bases as a second problem. We address this problem by presenting\r\nI-HARE, an approximation technique for calculating the overall ranking scores of a knowledge without the need to recalculate the ranking from scratch at each new revision. We evaluate our approaches by calculating ranks on the 3 × 10^9 and 2.4 × 10^9 triples from Wikidata resp. LinkedGeoData. Our evaluation demonstrates\r\nthat D-HARE is the first holistic approach for computing ranks on very large RDF knowledge graphs. In addition, our incremental approach achieves a root mean squared error of less than 10E−7 in the best case. Both D-HARE\r\n and I-HARE are open-source and are available at: https://github.com/dice-group/incrementalHARE.\r\n","lang":"eng"}],"doi":"10.1145/3342220.3343660","project":[{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"page":"163-171","publication":"Proceedings of the 30th ACM Conference on Hypertext and Social Media  - HT '19","type":"conference","publication_status":"published","citation":{"ama":"Desouki AA, Röder M, Ngonga Ngomo A-C.

Assuming an enrollment utterance of the target speakeris available, the so-called SpeakerBeam concept has been recently proposed to extract the target speaker from a speech mixture. If multi-channel input is available, spatial properties of the speaker can be exploited to support the source extraction. In this contribution we investigate different approaches to exploit such spatial information. In particular, we are interested in the question, how useful this information is if the target speaker changes his/her position. To this end, we present a SpeakerBeam-based source extraction network that is adapted to work on moving speakers by recursively updating the beamformer coefficients. Experimental results are presented on two data sets, one with articially created room impulse responses, and one with real room impulse responses and noise recorded in a conference room. Interestingly, spatial features turn out to be advantageous even if the speaker position changes.","lang":"eng"}],"project":[{"name":"Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"oa":"1","user_id":"59789","date_created":"2019-11-06T09:43:03Z","status":"public","year":"2019","language":[{"iso":"eng"}],"file_date_updated":"2019-11-08T07:47:12Z","_id":"14822","date_updated":"2022-01-06T06:52:06Z","author":[{"last_name":"Heitkaemper","id":"27643","first_name":"Jens","full_name":"Heitkaemper, Jens"},{"full_name":"Feher, Thomas","first_name":"Thomas","last_name":"Feher"},{"first_name":"Michael","full_name":"Freitag, Michael","last_name":"Freitag"},{"id":"242","last_name":"Haeb-Umbach","full_name":"Haeb-Umbach, Reinhold","first_name":"Reinhold"}],"citation":{"bibtex":"@inproceedings{Heitkaemper_Feher_Freitag_Haeb-Umbach_2019, title={A Study on Online Source Extraction in the Presence of Changing Speaker Positions}, booktitle={International Conference on Statistical Language and Speech Processing 2019, Ljubljana, Slovenia}, author={Heitkaemper, Jens and Feher, Thomas and Freitag, Michael and Haeb-Umbach, Reinhold}, year={2019} }","mla":"Heitkaemper, Jens, et al. “A Study on Online Source Extraction in the Presence of Changing Speaker Positions.” <i>International Conference on Statistical Language and Speech Processing 2019, Ljubljana, Slovenia</i>, 2019.","short":"J.

Recently, the spectral characteristics of a target speaker, extracted from an adaptation utterance, have been used to guide a neural network mask estimator to focus on that speaker. In this work we present two variants of speakeraware neural networks, which exploit both spectral and spatial information to allow better discrimination between target and interfering speakers. Thus, we introduce either a spatial preprocessing prior to the mask estimation or a spatial plus spectral speaker characterization block whose output is directly fed into the neural mask estimator. The target speaker’s spectral and spatial signature is extracted from an adaptation utterance recorded at the beginning of a session. We further adapt the architecture for low-latency processing by means of block-online beamforming that recursively updates the signal statistics. Experimental results show that the additional spatial information clearly improves source extraction, in particular in the same-gender case, and that our proposal achieves state-of-the-art performance in terms of distortion reduction and recognition accuracy.","lang":"eng"}],"has_accepted_license":"1","_id":"14824","file_date_updated":"2019-11-08T07:46:37Z","date_updated":"2022-01-06T06:52:07Z","ddc":["000"],"publication":"INTERSPEECH 2019, Graz, Austria","date_created":"2019-11-06T10:04:49Z","type":"conference","year":"2019","language":[{"iso":"eng"}],"status":"public"},{"oa":"1","user_id":"59789","citation":{"mla":"Kanda, Naoyuki, et al. “Guided Source Separation Meets a Strong ASR Backend: Hitachi/Paderborn University Joint Investigation for Dinner Party ASR.” <i>INTERSPEECH 2019, Graz, Austria</i>, 2019.","bibtex":"@inproceedings{Kanda_Boeddeker_Heitkaemper_Fujita_Horiguchi_Haeb-Umbach_2019, title={Guided Source Separation Meets a Strong ASR Backend: Hitachi/Paderborn University Joint Investigation for Dinner Party ASR}, booktitle={INTERSPEECH 2019, Graz, Austria}, author={Kanda, Naoyuki and Boeddeker, Christoph and Heitkaemper, Jens and Fujita, Yusuke and Horiguchi, Shota and Haeb-Umbach, Reinhold}, year={2019} }","short":"N.

The main challenges of ASR systems for dinner party recordings obtained by multiple microphone arrays are (1) heavy speech overlaps, (2) severe noise and reverberation, (3) very natural onversational content, and possibly (4) insufficient training data. As an example of a dinner party scenario, we have chosen the data presented during the CHiME-5 speech recognition challenge, where the baseline ASR had a 73.3% word error rate (WER), and even the best performing system at the CHiME-5 challenge had a 46.1% WER. We extensively investigated a combination of the guided source separation-based speech enhancement technique and an already proposed strong ASR backend and found that a tight combination of these techniques provided substantial accuracy improvements. Our final system achieved WERs of 39.94% and 41.64% for the development and evaluation data, respectively, both of which are the best published results for the dataset. We also investigated with additional training data on the official small data in the CHiME-5 corpus to assess the intrinsic difficulty of this ASR task."}],"has_accepted_license":"1","project":[{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"_id":"14826","file_date_updated":"2019-11-08T07:45:15Z","date_updated":"2022-01-06T06:52:07Z","ddc":["000"],"publication":"INTERSPEECH 2019, Graz, Austria","date_created":"2019-11-06T10:08:49Z","status":"public","type":"conference","year":"2019","language":[{"iso":"eng"}]},{"page":"135-146","type":"conference","ddc":["006"],"publication":"Proceedings - 29.
