Abstract
The invention relates to a method for speech processing in which input variables containing speech features are mapped onto output variables. In the mapping process, the input variables are weighted and/or identical maps are produced for different sets of input variables and at least one output variable.
Claims27
A method of speech processing, comprising:
- mapping input variables with different weights onto at least one output variable produced by said mapping;
- comparing the at least one output variable produced from said mapping with a desired output variable to be produced from said mapping to obtain a comparison result;
- and
- calculating a change rule for said mapping based on the comparison result and to reduce the weights of selected input variables having little influence on the at least one output variable.

A system, comprising:
- a map unit to map input variables with different weights onto at least one output variable produced by said mapping;
- comparison unit to compare the at least one output variable produced from said mapping with a desired output variable to be produced from said mapping to obtain a comparison result;
- and
- a calculation unit to calculate a change rule for said mapping based on the comparison result and to reduce the weights of selected input variables having little influence on the at least one output variable.

At least one computer readable medium storing at least one computer program for controlling a processor to perform a method comprising:
- mapping input variables with different weights onto at least one output variable produced by said mapping;
- comparing the at least one output variable produced from said mapping with a desired output variable to be produced from said mapping to obtain a comparison result;
- and
- calculating a change rule for said mapping based on the comparison result and to reduce the weights of selected input variables having little influence on the at least one output variable.
