Book Description
We present results of a feasibility study on the use of linear predictive coding (LPC) techniques for deriving an objective measure of intelligibility over voice communication channels. Background material is given and several potentially useful measures are identified. The limitations of the present study are detailed and methods of overcoming these limitations in future work are outlined. In spite of these limitations, the study strongly supports the suitability of LPC techniques for the objective measurement of intelligibility. (Author).

Book Description
The comprehension of narrowband digital speech with bit errors was tested by using a sentence verification task. The use of predicates that were either strongly or weakly related to the subjects (e.g., A toad has warts./ A toad has eyes.) varied the difficulty of the verification task. The test conditions included unprocessed and processed speech using a 2.4 kb/s (kilobits per second) linear predictive coding (LPC) voice processing algorithm with random bit error rates of 0%, 2%, and 5%. In general, response accuracy decreased and reaction time increased with LPC processing and with increasing bit error rates. Weakly related true sentences and strongly related false sentences were more difficult than their counterparts. Interactions between sentence type and speech processing conditions are discussed. Keywords: Intelligibility; Voice communications; Speech recognition; Speech transmission.

Book Description
Written by the world's top experts in the field, this multidisciplinary book explores all phases of speech technology. Topics covered include: Conversion of computerized (keyboarded) text into synthesized speech, aimed at developing "talking computers" Development of automatic speech recognition, allowing electronic devices to process verbal commands Speech training and the use of synthesized speech for the hearing- and speech-impaired In-depth discussions of specific speech technologies are included, as well as a treatment of the issues and challenges of human-computer interfaces. Oriented toward state-of-the-art applications, the book emphasizes the practical utilization of emerging technologies and includes numerous case studies.
