Classification: G10L,H04M

Abstract:
An information signal content authoring system, comprising:a speech analyzer, responsive to a spoken utterance signal provided by a narrator, the spoken utterance signal being representative of information available to the narrator, the speech analyzer generating a speech signal representative of at least one prosodic parameter associated with the narrator;a text-to-speech converter, responsive to a text signal representative of the information available to the narrator, the converter generating a phonetic representation signal from the text signal and synthesizing a speech signal from the text signal, the text-to-speech converter also generating at least one prosodic parameter from the text signal;a spectrum comparator, operatively coupled to the speech analyzer and the text-to-speech converter, for comparing the at least one prosodic parameter of the speech signal generated by the speech analyzer to the speech signal synthesized by the converter and generating a variance signal indicative of a spectral distance between the two speech signals, the variance signal being provided to the text-to-speech converter to adjust the at least one prosodic parameter; andan output portion, operatively coupled to the text-to-speech converter, for outputting the phonetic representation signal and the at least one prosodic parameter from the converter as a composite encoded signal representative of information content available to the narrator.
