Such ASR systems are typically required, e.g., for meeting transcription. We provide an efficient implementation based on a dynamic programming search in a multi-dimensional Levenshtein distance tensor under the constraint that a reference utterance must be matched consistently with one hypothesis output. This also results in an efficient implementation of the ORC WER which previously suffered from exponential complexity. We give an overview of commonly used WER definitions for multi-speaker scenarios and show that they are specializations of the above MIMO WER tuned to particular application scenarios. We conclude with a discussion of the pros and cons of the various WER definitions and a recommendation when to use which.}}, author = {{von Neumann, Thilo and Boeddeker, Christoph and Kinoshita, Keisuke and Delcroix, Marc and Haeb-Umbach, Reinhold}}, booktitle = {{ICASSP 2023 - 2023 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)}}, keywords = {{Word Error Rate, Meeting Recognition, Levenshtein Distance}}, publisher = {{IEEE}}, title = {{{On Word Error Rate Definitions and Their Efficient Computation for Multi-Speaker Speech Recognition Systems}}}, doi = {{10.1109/icassp49357.2023.10094784}}, year = {{2023}}, } @inproceedings{48275, abstract = {{MeetEval is an open-source toolkit to evaluate all kinds of meeting transcription systems. It provides a unified interface for the computation of commonly used Word Error Rates (WERs), specifically cpWER, ORC WER and MIMO WER along other WER definitions. We extend the cpWER computation by a temporal constraint to ensure that only words are identified as correct when the temporal alignment is plausible. This leads to a better quality of the matching of the hypothesis string to the reference string that more closely resembles the actual transcription quality, and a system is penalized if it provides poor time annotations. Since word-level timing information is often not available, we present a way to approximate exact word-level timings from segment-level timings (e.g., a sentence) and show that the approximation leads to a similar WER as a matching with exact word-level annotations. At the same time, the time constraint leads to a speedup of the matching algorithm, which outweighs the additional overhead caused by processing the time stamps.}}, author = {{von Neumann, Thilo and Boeddeker, Christoph and Delcroix, Marc and Haeb-Umbach, Reinhold}}, booktitle = {{Proc.

Eine Möglichkeit liegt dabei in der Entwicklung theoretisch fundierter und praxisorientierter digitalisierungsbezogener Ressourcen, die für diese Zwecke genutzt werden können. Um solche Ressourcen zu entwickeln, erscheint der Ansatz der phasenübergreifenden Zusammenarbeit in Communities of Practice (CoPs) der Lehrkräftebildung vielversprechend, da hier die Expertise aller Phasen genutzt werden kann. Bisherige Forschungsergebnisse zu Gelingensbedingungen der Zusammenarbeit lassen auf Faktoren wie Zielorientierung, Aufgabenbewältigung, Zusammenhalt oder Verantwortungsübernahme schließen, beziehen sich jedoch überwiegend auf Teams im Allgemeinen oder CoPs aus dem Wirtschaftskontext. Bisher unerforscht sind damit Gelingensbedingungen für die phasenübergreifende Zusammenarbeit in der Lehrkräftebildung, weshalb der vorliegende Beitrag diese Thematik untersucht. Zur Bearbeitung dieses Forschungsdesiderates werden quantitative und qualitative Daten aus dem COMeIN-Verbundvorhaben (Communities of Practice für eine innovative Lehrkräftebildung in NRW) herangezogen. Mittels einer multiplen Regressionsanalyse wurde die Aufgabenbewältigung in den CoPs als zentraler Prädiktor für positiv wahrgenommene phasenübergreifende Zusammenarbeit identifiziert. Die qualitative Inhaltsanalyse verdeutlicht zudem u.a. die hohe Relevanz der Beachtung der unterschiedlichen Systemlogiken der lehrkräfte-bildenden Phasen.

We performed our systematic study on the example of the 3D Manufacturing Format (3MF), which offers a large variety of features that could lead to critical attacks. Based on 3MF’s features, we systematized three attack goals: Data Exfiltration (dex), Denial of Service, and UI Spoofing (uis). We achieve these goals by exploiting the complexity of 3MF, which is based on the Open Packaging Conventions (OPC) format and uses XML to define 3D models. In total, our analysis led to 352 tests.
