Abstract

Apparatus for detecting a fundamental frequency in speech utilizing a plurality of voiced detectors and selecting (104, 105) one of those detectors to make the voicing decision utilizing distance measurement values with each value generated by one of the voiced detectors. The voiced detector selected is the one which generated the best distance measurement value. The distance measurement value may be the Mahalanobis distance value or Hotelling's two-sample T<2> statistic. Two types of voiced detectors are disclosed: statistical voiced detectors (103) and discriminant voiced detectors (107). The disclosed statistical voiced detector adapts to changing speech environments by detecting changes in the voice environment in response to classifiers that define certain attributes of the speech.
