Speech rate production and perception

Talkers produce speech at different rates, depending on factors that vary between talkers (age, gender, regional background, etc.) and within talkers (register, emotion, etc.). This research program focuses on the question how talkers manage to produce speech at different rates, on the one hand, and how listeners are able to understand speech produced at different rates, on the other hand. Researchers in this project use behavioral, neuro-imaging (oscillatory dynamics), and computational methods (modeling).

Keywords: speech planning; computational modeling; rate normalization; neural oscillations; entrainment.

About this research program:

Research centres around three main topics:

 

1. Variation in speech rate production

Joe Rodd (PhD student), Hans Rutger Bosker, Louis ten Bosch, Antje Meyer, Mirjam Ernestus

We investigate the psychological mechanisms underlying the short-term regulation of speech rate. Talkers can speak at different rates, speeding up or slowing down as required by the communicative situation. Although the regulation of speech rate clearly is an important component of our communicative skills set, there has hardly been any research into the underlying psycholinguistic mechanisms. The project includes two tightly linked components: the development of a computationally implemented model of speech planning that captures speaking at different rates and a series of experiments designed to assess predictions of the model. Results of this research contribute to our understanding of the regulation of speech rate and to theories about the interface of the speech production system with executive control and articulation.

2. Variation in speech rate perception

Hans Rutger Bosker, Eva Reinisch, Matthias Sjerps, Anne Kösem, Ole Jensen, Peter Hagoort, Oded Ghitza, Martin Cooke, Hugo Quené

We investigate how listeners are able to understand speech produced at different rates. Listeners are known to interpret temporal cues to phonemic contrasts (e.g., vowel length) relative to the speech rate of the surrounding context. We aim to reveal the auditory and cognitive mechanisms underlying rate normalization using behavioral methods and neuro-imaging (MEG). Work is performed within a neurobiological framework, involving entrainment (phase-locking) of endogenous oscillations in the brain to the slow amplitude modulations in the speech signal. Outcomes contribute to our understanding of speech perception in general and its neurobiological implementations.

3. Interface speech rate production - speech rate perception

Merel Maslowski (PhD student), Hans Rutger Bosker, Antje Meyer

The aim of this research strand is to investigate how speech rate production and speech rate perception interact. In natural conversation, our own speech and the speech of others follow each other in rapid succession. Context effects (such as rate normalization) are well known in speech perception but studies of how our own voice may influence our perception of others are scarce. We investigate how our own speech rate at a given moment in time changes the way we perceive others. We also try to investigate what role talkers’ habitual rates (some talkers are simply faster talkers than others) play in perception. Results contribute to our understanding of the interface between the production system and the comprehension system, and dialogue in general.
