The ATAROS (Automatic Tagging and Recognition of Stance) project aims to identify acoustic signals of stance-taking (opinions, evaluations, judgments, etc.) in order to inform the development of automatic stance recognition in natural speech. Because existing corpora generally have a low frequency of stance-taking in conversation, we have created an audio corpus of dyads completing collaborative tasks designed to elicit a high density of stance-taking at increasing levels of involvement. Funded by NSF grant IIS-1351034 awarded to PIs Gina-Anne Levow, Richard Wright, Mari Ostendorf.

Perceptual Adaptation to Distortions
This project examines several issues related to speech perception under conditions of distortion (i.e., hearing loss, hearing aid amplification, dialect, foreign accent, etc). Current work is focused on cross-dialect perception and talker familiarity, and how they interact with hearing loss of different types. This research is funded by NIDCD flowthrough funds to Pamela Souza at Northwestern University (NIH grant R01DC006014), and is a collaboration with Northwestern's Hearing Aid Lab.

PHOIBLE (Phonetics Information Base and Lexicon) is a knowledge base of phonological inventories, structured as a queryable and extensible mathematical graph. The knowledge base includes allophonic detail for many languages, and all phones are encoded as IPA unicode and as vectors of distinctive features, allowing "fuzzy" queries for classes of sounds instead of searching using individual glyphs. As of January 2012, there were over 1500 languages included.

The Vocal Joystick Project seeks to develop a continuous and discrete control device based on continuous and discrete dimensions of human vocalizations. There are four continuous dimensions that can be extracted from vowel-like vocalizations: vowel height, vowel backness, pitch, and intensity. In addition to these, discrete control can be achieved through brief obstruent-like sounds and through words. The extracted dimensions can be used as control parameters for a variety of devices. The most obvious application is computer control in GUI environments, but applications also include robotic arms, thermostats, and lighting levels.
