Normalization of vector codebook data for audio-visual speech recognition.

摘要

A normalization coefficient is determined for normalizing characteristic parameters. A distance is calculated to a standard parameter with respect to each of a plurality of characteristic parameters normalized. A normalization coefficient is changed such that the distance with respect to an arbitrary one of a plurality of characteristic parameters and a distance with respect to another arbitrary one of the plurality of characteristic parameters are equal to each other. Application to inter-media normalization and the audio-visual recognition of speech.
