Mixed Distance Measures for Optimizing Concatenative Vocabularies for Speech Synthesis: A Thesis Proposal
Synthesized speech from text-to-speech systems is generally produced from the concatenation of small units of speech. The concatenation process can be complex, involving smoothing and context dependent adjustments to the speech. The overall quality of the speech produced will depend in large part on the quality of the elements used for concatenation. Selection and evaluation of these elements has been done entirely by hand. The proposed work addresses the process by which these concatenative elements are created from a natural voice and optimized. The optimization uses distance measures which exploit detailed information on the structure of the speech signals

A Distributed Signal Processing Facility for Speech Research
An interactive digital voice laboratory facility has been developed to allow the sharing of expensive signal processing resources among large numbers of interactive display devices. The environment considered in this work is a facility in which there are a moderate number of heterogeneous systems with extensive floating point numerical capability. In this environment there are a number of voice I/O terminals with the capability to display and play voice in a variety of ways. Using shared me access and remote procedure calls, any of the voice workstations may have signal processing jobs performed on any of the available floating point processors without explicit knowledge of where the computation is being performed. The appearance to the user of the voice workstation is that of a workstation with enormous resources
