Speech Representation, Perception and Recognition

Speaker(s):

Bob McMurray

Bob McMurray, U. Iowa Abstract: One of the most challenging aspects of speech perception is the rampant variability in the signal. One consequence of this variability is that purely bottom up approaches to categorizing phonemes have not consistently...

Speech Representation, Perception and Recognition

Speaker(s):

Karen Livescu

Karen Livescu, TTI Abstract: For a number of speech tasks, it can be useful to represent speech segments of arbitrary length by fixed-dimensional vectors, or embeddings. In particular, vectors representing word segments -- acoustic word embeddings...

Entrainment, segmentation, and decoding: three necessary computations for speech comprehension

Speech Representation, Perception and Recognition

Speaker(s):

David Poeppel

David Poeppel, Max-Planck-Institute and NYU Abstract: Neurophysiological experiments demonstrate that auditory cortical activity entrains to continuous speech. This entrainment, building on neural oscillations, underlies segmentation, and the...

The role(s) of hemispheric asymmetries and streams of processing in speech perception.

Speech Representation, Perception and Recognition

Speaker(s):

Sophie Scott

Sophie Scott, UCL Abstract: I will talk about the potential for different perceptual representations of the speech signal and their relationship to anatomical and task based factors.

Speaker(s):

Abdelrahman Mohamed

Abdelrahman Mohamed, Microsoft Research Abstract: In the past decade, the ASR technology made a huge leap forward in terms of word recognition accuracy, leading to the recent announcement of Microsoft of achieving human parity in conversational...

Speech Representation, Perception and Recognition

Speaker(s):

Keith Johnson

Keith Johnson, UC Berkeley Abstract: At one point in my research career I was interested in finding “the” representation of speech. But clearly, there is no one level of speech representation. Researchers find it useful to represent speech in a...

Carmen Varela

Carmen Varela, a research scientist at MIT, highlights the importance of interdisciplinarity in the study of intelligence, focusing on the hippocampus and its role in the formation of new memories and encoding of spatial information to support...
