VOICE SIGNAL PERTURBATION FOR SPEECH RECOGNITION |
摘要 |
A system (100) and method (200) for generating a perturbed phonetic string for use in speech recognition. The method can include generating (202) a feature vector set from a spoken utterance, applying (204) a perturbation to the feature vector set for producing a perturbed feature vector set, and phonetically decoding (206) the perturbed feature vector set for producing a perturbed phonetic string. The perturbation mimics environmental variability and speaker variability for reducing the number of spoken utterances in speech recognition applications.
