System and method of speech recognition for non-native speakers of a language
First Claim
1. An accent compensative speech recognition system for use with a signal processor generating at least one feature vector based upon a voice-induced electrical signal, the system comprising:
- a first-language acoustic module determining a first-language phoneme sequence based upon the at least one feature vector; and
a second-language lexicon module determining a second-language speech segment based upon the first-language phoneme sequence.

Abstract
An accent compensative speech recognition system and related methods for use with a signal processor generating one or more feature vectors based upon a voice-induced electrical signal are provided. The system includes a first-language acoustic module that determines a first-language phoneme sequence based upon one or more feature vectors, and a second-language lexicon module that determines a second-language speech segment based upon the first-language phoneme sequence. A method aspect includes the steps of generating a first-language phoneme sequence from at least one feature vector based upon a first-language phoneme model, and determining a second-language speech segment from the first-language phoneme sequence based upon a second-language lexicon model.

15. A computer readable storage medium for use with a data communication network having a plurality of hosts, a plurality of edge nodes connected to the hosts, and at least one core node connected to the edge nodes, the storage medium comprising computer instructions for:
-
generating a first-language phoneme sequence from the at least one feature based upon a first-language phoneme model; and
determining a second-language speech segment from the first-language phoneme sequence based upon a second-language lexicon model. - View Dependent Claims (16, 17, 18, 19, 20, 21)
