First-order preference theories and their applications | This dissertation begins with a logical analysis of the notion of preference. Earlier approaches to logical analysis of preference are surveyed and their shortcomings pointed out. Next, a family of modal logics of preference is presented with soundness and completeness results for both the propositi... | | 1992-12 |

A priori digital speech analysis | Abstract: This paper describes a priori digital speech analysis. This method takes advantage of the quasi-periodic nature of voice speech sounds to reduce the amount of computation needed to obtain the analysis parameters. The vocal tract is modeled as an all-pole digital filter (predictive coding)... | speech analysis; predictor coefficients; pitch period | 1973-03 |
