Voice Transformation and Detection
Agency / Branch:
DOD / USAF
Research into voice transformation has been ongoing for over twenty years. In addition, there are many commercial products available. There has been very little research, however, into techniques for detection of voice transformation. Furthermore, objective metrics for the quality of transformed speech - which could serve as a basis for the detection of transformed speech - are practically nonexistent. All discussions of the quality of voice transformation algorithms use subjective terms, though there is tacit acknowledgement that artifacts exist. This proposal describes research into the application of conventional signal processing techniques to the identification of the artifacts that result from voice transformation, and into the implementation of objective criteria for automatic blind-detection of voice transformation.
