Formant and F0 Features for Speaker Verification
In this paper, the feature set of fundamental frequency, formant center frequencies, and formant bandwidths were used in speaker verification experiments using the database distributed by the Speaker Odyssey Workshop. The features were extracted using the Entropic Signal Processing System. The main classifier was a Gaussian Mixture Model system built by MIT Lincoln Laboratory, but tests were al...
متن کاملF0 and Segment Duration in Formant Synthesis of Speaker Age
This paper describes the work with F0 and segment duration when developing a prototype system for analysis of speaker age using data-driven formant synthesis. The system was developed to extract 23 parameters from the test words—spoken by four differently aged female speakers of the same dialect and family—and to generate synthetic copies. Audio-visual feedback enabled the user to compare the n...
متن کاملOn-line formant shifting as a function of F0
We investigate whether there is a within-speaker effect of a higher F0 on the values of the first and the second formant. When asked to speak at a high F0, speakers turn out to raise their formants as well. In the F1 dimension this effect is greater for women than for men. We conclude that the general formant raising effect might be due to the physiology of a high F0 (i.e. raised larynx and sho...
متن کاملInstrumental Variables Regression with Measurement Errors and Multicollinearity in Instruments
In this paper we obtain a consistent estimator when there exist some measurement errors and multicollinearity in the instrumental variables in a two stage least square estimation of parameters. We investigate the asymptotic distribution of the proposed estimator and discuss its properties using some theoretical proofs and a simulation study. A real numerical application is also provided for mor...
متن کاملCharacterizing Result Errors in Internet Desktop Grids
Desktop grids use the free resources in Intranet and Internet environments for large-scale computation and storage. While desktop grids offer a high return on investment, one critical issue is the validation of results returned by participating hosts. Several mechanisms for result validation have been previously proposed. However, the characterization of errors is poorly understood. To study er...
