VOICE SYNTHESIS AND PROCESSING
First Claim
Patent Images
1. A machine-readable storage medium storing executable program instructions which when executed by a data processing system cause the data processing system to perform a method comprising:
- receiving a first audio recording of a human speech in a natural language; and
applying speech analysis synthesis algorithm to the first audio recording to synthesize a second audio recording from the first audio recording such that the second audio recording sounds humanistic and consistent, but unintelligible.

Abstract
A method and an apparatus for voice synthesis and processing have been presented. In one exemplary method, a first audio recording of a human speech in a natural language is received. Then speech analysis synthesis algorithm is applied to the first audio recording to synthesize a second audio recording from the first audio recording such that the second audio recording sounds humanistic and consistent, but unintelligible.

5. A computer-implemented method comprising:
-
dividing a first audio recording into a plurality of abstract sound units; synthesizing a second audio recording from the first audio recording by reversing each of the plurality of abstract sound units to generate the second audio recording; smoothing discontinuity at junctions of consecutive ones of the plurality of abstract sound units in the synthesized audio recording; and audibly rendering the second audio recording. - View Dependent Claims (6, 7, 8, 9)
