Dear colleagues and students, Following our previous announcement, we are pleased to share the updated programme for the half-day workshop Stable perception of spectral information across contexts: From normalization to adaptive category representations, which will take place on the morning of June 11th, in Stockholm (please see below). We would be grateful if you could continue to circulate this information within your networks, and we look forward to welcoming you to Stockholm in June. Best wishes, Anna Persson anna.persson(a)su.se Stable perception of spectral information across contexts: From normalization to adaptive category representations Time: Thursday 11 June, 8.30-12.00 Place: Pärlan, Campus Albano (House 1, floor 6) One of the striking features of human speech perception is its stability: despite substantial between-talker differences arising from variation in vocal tract physiology, language background, and social factors, listeners typically understand speech with relative ease. This workshop focuses on the auditory mechanisms thought to contribute to such stable perception by normalizing the speech signal for differences in vocal tract size and/or shape. More specifically, the workshop aims to connect research on the early normalization of formant and other spectral information with work on downstream adaptive mechanisms beyond formants. Support for the existence of formant/spectral normalization has come from behavioral experiments on speech perception, brain imaging studies, brain stem recordings, and cross-species comparisons. However, important questions remain concerning the computations underlying these rapid and seemingly automatic mechanisms, as well as the extent to which they interact with top-down information from higher-level representations of linguistic categories and contexts. By bringing together researchers with complementary perspectives from phonetics, cognitive science, neuroscience, and speech technology, the workshop aims to foster focused discussions of open questions concerning speech perception, adaptation, and formant/spectral normalization. Thanks to generous support from Riksbankens Jubileumsfond, the workshop is open to all and free of charge.
