Perceptual feedback in speech production (speech motor control)

The speech sensorimotor feedback procedure, which introduces real-time sensory perturbations as participants speak (e.g., saying “ship” but hearing “sheep”), offers a unique window into the inner workings of speech behaviors. Crucially, the speech sensorimotor adaptation procedure induces predictable changes in perception and production (Lametti et al., 2014), suggesting its potential as an intervention tool. 

My ongoing work is accumulating promising results, showing that this procedure can lead to preferable changes in the perception and production of second language learners (L1 Spanish, L2 English) in the /i/-/ɪ/ contrast.
