Abstract
An information processing apparatus includes a feature parameter detector for detecting feature parameters based on a plurality of input data, a normalizer for normalizing the feature parameters detected by the feature parameter detector while maintaining their feature components, and an integration unit for integrating the feature parameters normalized by the normalizer. In the information processing apparatus, feature parameters from a plurality of input data are normalized based on learning normalization coefficients, and distances from each of the normalized feature parameters and to a normal parameter are calculated. Based on the calculated distances, time-series normalization coefficients for performing speech recognition are determined for the feature parameters. Therefore, optimal normalization coefficients for recognizing the feature parameters at each point of time can be obtained.
