ABSTRACT:
Methods and apparatus of processing, storing and transmitting an original data stream of digitized speech samples. The method converts a stream of digitized speech samples to a stream of text and associated reliability measures. A mixed-media data stream is created with the stream of text as a text component and selected portions of the digitized stream of speech as a speech component. The selected portions are those whose corresponding reliability measures fall below a threshold. The threshold can be changed to change the amount of storage or bandwidth used by the mixed-media data stream. The mixed-media data stream can be searched and the results can be spoken as synthetic speech derived form the text component or as speech samples taken from the digitized speech component.
