Title:

SPEECH PROCESSING METHOD, SPEECH PROCESSING PROGRAM, AND SPEECH PROCESSING DEVICE

Document Type and Number:

WIPO Patent Application WO/2008/015800

Kind Code:

A1

Abstract:

A signal representing a nonaudible murmuring speech acquired through an in-vivo conduction microphone is converted into a signal representing a speech recognizable by the listener as correct as possible (hardly misrecognized). A speech processing method comprises a learning procedure (S7) for learning calculation of a model parameter of a vocal tract feature value conversion model showing the conversion characteristic of an acoustic feature value attributed to the vocal tract according to a learning input signal of a nonaudible murmuring speech colleted by an in-vivo conduction microphone and a learning output signal of an audible whispering speech corresponding to the learning input signal collected by a predetermined microphone and storing the model parameter after the learning in a predetermined storage means and a whispering speech converting procedure (S9) for converting the signal representing the nonaudible speech acquired through the in-vivo conduction microphone into a signal representing an audible whispering speech according to the vocal tract feature value conversion model for which the model parameter after the learning obtained by this is set.
