Dr. Wiltshire leads the Integrative Speech Research Group. 

The Integrative Speech Research Group takes an interdisciplinary approach to studying the speech production system. We are interested in how the brain and vocal tract work to produce speech. 

We use a range of methods, often combining them in novel ways, to address the entire speech system. The lab has expertise in:

Brain Imaging: fMRI, Multi-Parameter-Mapping, Diffusion Weighted Imaging, MRI-compatible fNear Infra-Red Spectroscopy. We have access to a research-dedicated 3T MRI in the basement!

Brain Stimulation: Transcranial Electrical Stimulation, Transcranial Magnetic Stimulation (Motor Evoked Potentials and repetitive protocols, MRI-guided technology)

Articulography: Vocal Tract (or Real Time) MRI, Electromagnetic Articulography

We work with typical speakers and those with diverse speech differences, including developmental and acquired stuttering and Parkinson's disease.  We work closely with charities, such as STAMMA to develop and share our work.

 We always use co-production methods when designing, running and sharing our work. Please get in touch if you are interested in working with us! 

We host a Journal Club with STAMMA (The British Stammering Association).

• DPhil: Investigating Speech Motor Control Using Vocal Tract Imaging, fMRI, and Brain Stimulation
  University of Oxford, 2020

Dr. Wiltshire's research aims to understand the neural control of speech production, with a specific interest in developmental stuttering. 

During her postdoctoral fellowship at the Institute for Phonetics and Speech Processing, Ludwig-Maximillains-University (LMU), Munich she combined brain stimulation techniques (Transcranial Magnetic Stimulation) and articulography (Electromagneticarticulography, vocal tract MRI) to investigate the neural processes underlying the initiation and inhibition of speech movements in people who stutter and people who are typically fluent.

Dr. Wiltshire completed her DPhil at the University of Oxford in 2020, with Kate Watkins. During her DPhil, she contributed to a large randomised control trial looking at whether tDCS can enhance fluency in people who stutter (INSTEP trial). Within this, she used a range of techniques, including tDCS, TMS and brain and vocal tract MRI, to investigate the neural control of speech in people who stutter and people who are typically fluent.

Anyone interested in postgraduate opportunties with the Integrative Speech Research Group should contact c.wiltshire@bangor.ac.uk in the first instance to informally discuss potential topics/interests.
