Error-preserving Automatic Speech Recognition of Young English Learners' Language

1 code implementation5 Jun 2024 Janick Michot, Manuela Hürlimann, Jan Deriu, Luzia Sauer, Katsiaryna Mlynchyk, Mark Cieliebak

In this work, we build an ASR system that satisfies these requirements: it works on spontaneous speech by young language learners and preserves their errors.

Favi-Score: A Measure for Favoritism in Automated Preference Ratings for Generative AI Evaluation

no code implementations3 Jun 2024 Pius von Däniken, Jan Deriu, Don Tuggener, Mark Cieliebak

Thus, we propose that preference-based metrics ought to be evaluated on both sign accuracy scores and favoritism.
