摘要
A method of modifying feature parameters for a speech recognition is provided. This method is provided with: a process of extracting the feature parameter from an input speech in a real environment; a process of reading a first speech transfer characteristic corresponding to an environment in which a reference pattern for the speech recognition is generated, from a first memory device; a process of reading a second speech transfer characteristic corresponding to the real environment from a second memory device; a process of modifying the extracted feature parameter according to the first speech transfer characteristic and the second speech transfer characteristic to convert the extracted feature parameter corresponding to the real environment into a modified feature parameter corresponding to the environment in which the reference pattern is generated.
