Phonological regularity, perceptual biases, and the role of phonotactics in speech error analysis
This talk investigates a set of phonological patterns in the SFU Speech Error Database (SFUSED), with the goal of understanding if and how phonological grammar is involved in online processes of phonological encoding. It assesses 2,076 sound errors in English of various types (phonological substitutions, deletions, additions, etc.) for their phonological regularity (do they violate English phonotactics?). The results show that sound errors are much less regular (violate phonotactics more often) than reported in prior work, and in some contexts to not deviate significantly from chance expectations. The higher degree of phonological irregularity is attributed to methodology, because the methods for collecting speech errors in SFUSED are demonstrably less prone to perceptual bias. While
phonological encoding may require linguistic representations of planning units (e.g., segments), these findings suggest that some of the tools of phonological grammars, like syllable-structure algorithms, may not be required in the retrieval of phonological segments in words.
