The Nebraska Acoustics Group (NAG) met regularly throughout the fall 2019 semester. At the September meeting, the shared acoustic nugget was on how Amazon Alexa uses semi-supervised learning to reduce speech recognition errors. In October, Kenton Hummel presented on his recent hospital acoustics work, and in the Halloween spirit, we shared a link on “Is That a Ghost? Vibroacoustic Explanations for False Poltergeists”. The November meeting featured a presentation by Jared Paine on his recent restaurant acoustics work, and we shared recent acoustic news on why quiet cars are getting louder, and how the voice can be used to be persuasive.
