Self-monitoring and control in speech production -

Internal and external self-monitoring for speech errors is largely production-based

Sieb Nooteboom and Hugo Quené - Utrecht institute of Linguistics OTS, Utrecht University, The Netherlands

We critically examine two propositions concerning self-monitoring for speech errors suggested by Levelt, Roelofs and Meyer (1999): (1) errors are detected both pre-articulatorily and post-articulatorily; (2) detection of errors is perception-based. In the literature we find much evidence for (1), but evidence for (2) is less convincing. In a SLIP experiment we assessed the detection rate separately for early and late detected errors, both with and without masking of normal auditory feedback. Results show that masking has no effect on detection rates, neither for early nor for late detected errors. Error-to-cut-off intervals and error-to-repair intervals are bimodal, separating early and late detected errors. The two distributions of error-to-cut-off intervals cross over at c. 400 ms. Apparently, there is a clear distinction between pre-articulatory and post-articulatory error detection and detection of segmental errors is not based on auditory perception. We argue that early and late error detection is mainly conflict-based.
