Speech Enhancement With Inventory Style Speech Resynthesis

We present a new method for the enhancement of speech. The method is designed for scenarios in which targeted speaker enrollment as well as system training within the typical noise environment are feasible. The proposed procedure is fundamentally different from most conventional and state-of-the-art denoising approaches. Instead of filtering a distorted signal we are resynthesizing a new “clean” signal based on its likely characteristics. These characteristics are estimated from the distorted signal. A successful implementation of the proposed method is presented. Experiments were performed in a scenario with roughly one hour of clean speech training data. Our results show that the proposed method compares very favorably to other state-of-the-art systems in both objective and subjective speech quality assessments. Potential applications for the proposed method include jet cockpit communication systems and offline methods for the restoration of audio recordings.

Writing the Unspeakable: an Ethical Approach to a Traumatized Narrative

This project uses the works of contemporary author Tim O’Brien, whose fiction often performs the trauma of the Vietnam War, to explore new ways of encountering the traumatized text. Informed by Emmanuel Levinas’s ethics of the face, and Sigmund Freud’s and Dominick LaCapra’s work on the narratology of the melancholic and the mourner, I consider the different ways we respond to the suffering Other and explore the paradox that through reading a traumatized narrative empathically we may come face-toface, as it were, with the suffering Other. If this is indeed the case, I reason, then the obligations that are due to the Other are also due to the text itself.
