Collecting a Corpus of Dutch Noise-Induced `Slips of the Ear'

When trying to understand how listeners recognise words, listeners' misperceptions, so-called `slips of the ear', can reveal important aspects of the underlying mechanisms of normal word recognition. Such misperceptions shed light onto how inferences are made by listeners about acoustic details in the speech signal and how these interact with other sound sources in the background. On the other hand, if speech from a particular speaker is more prone to being misperceived than that from another speaker, these misperceptions may also shed light onto speaker characteristics. To study these phenomena, misperceptions that occur consistently are invaluable. Although such confusions are quite rare, within the Marie Curie INSPIRE project, software has been developed to efficiently collect such consistent confusions for different languages. Using this software, we have started to collect Dutch consistent confusions. Single words, embedded in five different types of noise at different SNRs, produced by four speakers were presented to Dutch listeners. In a preliminary analysis, consistent confusions were analysed in terms of phoneme substitutions, insertions, and deletions, reconstructions of words using background noise, and eccentric cases. Moreover, the number and types of consistent confusions obtained in the different noise types and from different speakers are compared.
