Speaker normalization by means of paralinguistic transformations

Paralinguistic transformations (PT) change the information about a speaker's pitch, age and sex in a speech signal and leave the linguistic contents invariant. PTs are spectrum transformations and can be used to normalize speech, i.e. to compensate for variations in the speech signal due to differently shaped speech organs across speakers. The major such variations are caused by different vocal tract lengths that are directly related to the speaker's pitches. The corresponding PTs are direct functions of the fundamental frequency F0.

The focus of the project is on the following issues:
