A joint study of @UAM_Poznan researchers and Samsung Electronics Poland engineers on evaluating robustness of #NLU models to speech recognition errors was presented at #EMNLP2023 by @marekkubis and @tzietkiewicz arxiv.org/abs/2310.16609

Contrary to conventional adversarial attacks, which aim at determining the samples that deteriorate the model performance under study, our method also takes into consideration samples that change the NLU outcome in other ways.

The robustness criteria that we formulate are then used to construct a model for detecting speech recognition errors that impact the NLU model in the most significant way.

The augmented dataset is used to evaluate natural language understanding models and the outcomes of the evaluation serve as a basis for defining the criteria of NLU model robustness.

The method that we propose relies on the use of back transcription, a procedure that combines a text-to-speech model with an automatic speech recognition system to prepare a dataset contaminated with speech recognition errors.

Four of my students are going to discuss their research at @YRRSDS_Official. @poznanAI!
And YRRSDS 2023 has started! Looking forward to all the roundtable discussions and keynotes from @verena_rieser @malihealikhani & David Traum - stay tuned 👏👏
