The International Conference on Acoustics, Speech, and Signal Processing (ICASSP 2024) takes place April 14–19 in Seoul, South Korea. Amazon is a bronze sponsor of “the world’s largest and most comprehensive technical conference focused on signal processing and its applications.”

Amazon’s presence includes a workshop (Trustworthy Speech Processing), two of whose organizers are researchers with Amazon's Artificial General Intelligence (AGI) Foundations organization: Anil Ramakrishna, senior applied scientist, and Rahul Gupta, senior manager of applied science. In addition, Wontak Kim, senior manager of research science with Amazon Devices, will present a spotlight talk titled “Synthetic data for algorithm development: Real-world examples and lessons learned.”

As in previous years, many of Amazon’s accepted papers focus on automatic speech recognition. Topics such as speech enhancement, spoken-language understanding, and wake word recognition are all well represented. This year’s publications also touch on dialogue, paralinguistics, pitch estimation, and responsible AI. Below is a quick guide to Amazon’s more than 20 papers at the conference.

Rupak Vignesh Swaminathan, Grant Strimel, Ariya Rastrow, Harish Mallidi, Kai Zhen, Hieu Duy Nguyen, Nathan Susanj, Thanasis Mouchtaris

Graphic shows three 4 x 3 grids of green, yellow, and red dots connected by arrows; each has a black dot under the bottom dot in the first column and a white dot above the third column. The text <sos> turn on light appears to the left of each grid; the first grid has a title of utterance score (hyp1), the second has a title of utterance score (hyp2), and the third has a title of utterance score (hyp3). There are dotted line columns between the first and second grids with a two-way arrow marked margin connecting those grids.
A novel sequence-discriminative training criterion for automatic speech recognition (ASR) separates “good” and “bad” hypotheses in an N-best list produced from a pretrained transducer model. In this example, the three best hypotheses are fed back into the prediction network, after which the joint network lattice is computed to produce an utterance score for each hypothesis.
