USC-TIMIT is an extensive database of multimodal speech production data, developed to complement existing resources available to the speech research community and with the intention of being continuously refined and augmented. The database currently includes real-time magnetic resonance imaging data from five male and five female speakers of American(More)
For early vertebrates, a long-standing hypothesis is that vertebrae evolved as a locomotor adaptation, stiffening the body axis and enhancing swimming performance. While supported by biomechanical data, this hypothesis has not been tested using an evolutionary approach. We did so by extending biomimetic evolutionary analysis (BEA), which builds physical(More)
In this work, we analyzed a 96-hour corpus of married couples spontaneously interacting about a problem in their relationship. Each spouse was manually coded with relevant session-level perceptual observations (e.g., level of blame toward other spouse, global positive affect), and our goal was to classify the spouses' behavior using features derived from(More)
We present MRI-TIMIT: a large-scale database of synchronized audio and real-time magnetic resonance imaging (rtMRI) data for speech research. The database currently consists of speech data acquired from two male and two female speakers of Amer-ican English. Subjects' upper airways were imaged in the mid-sagittal plane while reading the same 460 sentence(More)
Realtime MRI provides useful data about the human vocal tract, but also introduces many of the challenges of processing high-dimensional image data. Intuitively, data reduction would proceed by finding the air-tissue boundaries in the images, and tracing an outline of the vocal tract. This approach is anatomically well-founded. We explore an alternative(More)
Water vapor profiles from NASA's Lidar Atmospheric Sensing Experiment (LASE) system acquired during the ARM/FIRE Water Vapor Experiment (AFWEX) are used to characterize upper troposphere water vapor (UTWV) measured by ground-based Raman lidars, radiosondes, and in situ aircraft sensors. Initial comparisons showed the average Vaisala radiosonde measurements(More)
Observational methods are fundamental to the study of human behavior in the behavioral sciences. For example, in the context of research on intimate relationships, psychologists' hypotheses are often empirically tested by video recording interactions of couples and manually coding relevant behaviors using standardized coding systems. This coding process can(More)
Interaction synchrony among interlocutors happens naturally as people adapt their speaking style gradually to promote efficient communication. In this work, we quantify one aspect of interaction synchrony-prosodic entrainment, specifically pitch and energy, in married couples' problem-solving interactions using speech signal-derived measures. Statistical(More)
Psychology is often grounded in observational studies of human interaction behavior, and hence on human perception and judgment. There are many practical and theoretical challenges in observational practice. Technology holds the promise of mitigating some of these difficulties by assisting in the evaluation of higher level human behavior. In this work we(More)
