Praat Vocal Toolkit

This command changes the characteristics of the second selected Sound to match those of the first selected Sound (voice conversion).

It combines six "Copy" commands into one:

• Copy vocal tract size
• Copy pitch contour
• Copy pitch median and variation
• Dynamic time warping (DTW)
• Copy duration (stretch)
• Copy EQ curve

It also combines three "Process" commands to apply specific modification parameters to the second selected Sound:

• Change vocal tract size
• Change pitch median and variation
• Change duration (stretch)

The resulting new Sound will appear selected in the list of objects.

Vocal tract length estimation adapted from the procedure described at:
Resonant frequencies and the vocal tract length

Vocal tract size change adapted from the script "VTchange" by Chris Darwin,
