Parsing Conversational Speech
University of Washington –
With recent advances in automatic speech recognition (ASR), there are increasing opportunities for natural language processing of speech, including applications such as speech understanding, summarization and translation. Parsing can play an important role here, but much of current parsing technology has been developed on written text.
Spontaneous speech differs substantially from written text, posing challenges for parsing that include the absence of punctuation and the presence of disfluencies and ASR errors. Prosodic cues can help fill in this gap, and there is a long history of linguistic research indicating that prosodic cues in speech can provide disambiguating context beyond that available from punctuation. However, leveraging prosodic cues can be challenging, because of the many roles prosody serves in speech communication. This talk looks at means of leveraging prosody combined with lexical cues and ASR uncertainty models to improve parsing (and recognition) of spontaneous speech. The talk will begin with an overview of studies of prosody and syntax, both perceptual and
computational. The focus of the talk will be on our work with a state-of-the-art statistical parser, discussing the issues of sentence segmentation, disfluencies, sub-sentence prosodic constituents, and ASR uncertainty. In addition, we show how these issues impact the use of parsing language models in ASR. We conclude by highlighting challenges in speech processing that impact parsing, including tighter integration of ASR and parsing, as well as portability to new domains.

Workshop “Metabolism and mathematical models: Two for a tango” – 2nd Edition
Title: Workshop Metabolism and mathematical models: Two for a tango – 2nd Edition
Dates: October 25-26, 2022
Location: This workshop will be held in a virtual way
The topic of this workshop is metabolism in general, with a special focus, although not exclusive, on parasitology. Besides an exploration of the biological, biochemical and biomedical aspects, the workshop will also aim at presenting some of the mathematical modelling, algorithmic theory and software development that have become crucial to explore such aspects.
This workshop is being organised in the context of two projects, both with the Inria European Team Erable. One of the projects involves a partnership with the University of São Paulo (USP), in São Paulo, Brazil, more specifically the Institute of Mathematics and Statistics (IME) and the Institute of Biomedical Sciences – Inria Associated Team Capoeira – and the other involves the Inesc-ID/IST in Portugal, ETH in Zürich and EMBL in Heidelberg – H2020 Twinning Project Olissipo.
The workshop is open to all members of these two projects but also, importantly, to the community in general.
The program and more details are available here.
