Evaluating a speech interface system for an ICU

This Thesis presents the development and evaluation of a speech I/O interface system for a bedside data entry application in an intensive care unit. The speech I/O interface consists of a speech recognition input and a speech generation output. The main objective is to permit users to perform "hands-free" and "eyes-free" data entry. This thesis begins with a literature survey of patient data management systems, speech applications, the difficulties and the key factors of speech evaluations. This is followed by an overview of the current system. The design and the implementation of the speech interface system are described. The evaluation scheme and test results are presented and discussed followed by an outline of future work and recommendations for the system
