Optical character recognition (OCR) engines work poorly on texts published with premodern printing technologies. Engaging the key technological contributors from the IMPACT project, an earlier project attempting to solve the OCR problem for early modern and modern texts, the Early Modern OCR Project (eMOP) of Texas A8M received funding from ...

Sign language is the primary medium of communication for many people who are deaf or hard of hearing. Members of this community access online sign language (SL) content posted on video sharing sites to stay informed. Unfortunately, locating SL videos can be difficult since the text-based search on video sharing ...

We present an articulatory-to-acoustic mapping for real-time articulatory synthesis.The method uses a deep neural network with a tapped-delay input line.Tapped-delay line efficiently captures dynamics in articulatory trajectories.The model achieved higher accuracy than competing models based on Gaussian mixtures.The improvement was also found perceivable in a subjective listening test. The conventional ...

We present a multitier system for the remote administration of speech therapy to children with apraxia of speech. The system uses a client-server architecture model and facilitates task-oriented remote therapeutic training in both in-home and clinical settings. The system allows a speech language pathologist (SLP) to remotely assign speech production ...

Biofeedback tools generally use visualizations to display physiological information to the user. As such, these tools are incompatible with visually demanding tasks such as driving. While auditory or haptic biofeedback may be used in these cases, the additional sensory channels can increase workload or act as a nuisance to the ...

Mass digitization of historical documents is a challenging problem for optical character recognition (OCR) tools. Issues include noisy backgrounds and faded text due to aging, border/marginal noise, bleed-through, skewing, warping, as well as irregular fonts and page layouts. As a result, OCR tools often produce a large number of spurious ...

We present a personalized biofeedback game that trains subjects to relax during gameplay. Training is achieved by increasing the game difficulty if the subject's breathing rate differs from a prescribed target. Personalization is achieved by adapting game difficulty to the subject's skill level, thus keeping the game challenging over long ...

We present Flappy Voice, a mobile game to facilitate acquisition of speech timing and prosody skills for children with apraxia of speech. The game is adapted from the popular game Flappy Bird, and replaces touch interaction with voice control. Namely, we map the child's vocal loudness into the bird's position ...

We present an auditory biofeedback technique that may be used as a tool for stress management. The technique encourages slow breathing by adjusting the quality of a music recording in proportion to the user's respiration rate. We propose two forms of acoustic degradation, one that adds white noise to the ...

This paper describes a new semi-supervised learning algorithm for intra-class clustering (ICC). ICC partitions each class into sub-classes in order to minimize overlap across clusters from different classes. This is achieved by allowing partitioning of a certain class to be assisted by data points from other classes in a context-dependent ...

We present an adaptive biofeedback game that aims to maintain the player's arousal level by monitoring physiological signals. We use concepts from control theory to model the interaction between human physiology and game difficulty during game play. We validate the approach on a car-racing game with real-time adaptive game mechanics. ...

The ability to measure a person's physiological parameters in a contact less fashion (i.e., without attaching electrodes to the skin) has tremendous potential in a number of applications, from affective interfaces to healthcare delivery. In this paper, we present a proof-of-concept method for measuring one such vital parameter, heart rate ...

We propose a concatenative synthesis approach to the problem of foreign accent conversion. The approach consists of replacing the most accented portions of nonnative speech with alternative segments from a corpus of the speaker's own speech based on their similarity to those from a reference native speaker. We propose and ...

Chronic stress is endemic to modern society. However, as it is unfeasible for physicians to continuously monitor stress levels, its diagnosis is nontrivial. Wireless body sensor networks offer opportunities to ubiquitously detect and monitor mental stress levels, enabling improved diagnosis, and early treatment. This article describes the development of a ...
