A new statistical pitch detection algorithm is proposed in this paper. It first defines frame-based voiced/unvoiced probabilistic measures and between-frame pitch transition probabilities, and then tightly integrates them into an ML search to find the best pitch contour of an utterance. Compared with the pitch detection method of the well-known ESPS(More)
This paper describes the design, construction and characterization of a subcarrier multiplexed broadband digital microwave radio link with Viterbi error control coding. The design and construction of the RF and microwave devices are described and analyzed. A key point of the research is that low cost materials could be used to implement a broadband wireless(More)
A prototype expert system, RAISON, has been developed to store and retrieve data using map-based and spreadsheet techniques on a microcomputer. The system uses knowledge-based rules to select the most appropriate model for a given set of data. Application to the data for Nova Scotia where the organic acidity is important necessitates modifications in the(More)
