Speech perception in the brain: Signals, systems and (a)symmetries

 

Speech perception in the brain: Signals, systems and (a)symmetries

At the beginning of the century, a functional imaging study using degraded signals to investigate the neural correlates of intelligibility provided a key breakthrough in the cognitive neuroscience of speech perception. In this study, the left anterior superior temporal sulcus showed greater activation during the perception of speech that could be understood, compared with listening to acoustically complex, unintelligible sounds. My talk will look at how the literature has developed since then, with specific reference to my own research. I will discuss the variety of degraded signals that we have used to probe speech perception, and the noise - across studies, between participants, within participants – that still limits our understanding of the underlying functional systems.
