Investigating Clear Speech Adaptations in Spontaneous Speech Produced in Communicative Settings
OT Tuomainen, Valerie L. Hazan · UCL Discovery (University College London) · 2018
In order to investigate the clear speech adaptations that individuals make when communicating in intelligibility-challenging conditions, it would seem essential to examine speech that is produced in interaction with a conversational partner. However, much of the literature on clear speech adaptations has been based on the analysis of sentences that talkers were instructed to read clearly. In this chapter, we review methods for eliciting spontaneous speech in interaction for the purpose of investigating clear speech phenomena. We describe in more detail the Diapix task (Van Engen et al., 2010) and DiapixUK picture pairs (Baker & Hazan, 2011) which have been used in the production of large corpora investigating clear speech adaptations. We present an overview of the analysis of spontaneous speech and clear speech adaptations from the LUCID corpora that include spontaneous speech recordings from children, young and older adults.
