Voice Morpher

The two most important parameters of a human voice are Pitch and Timbre, whose combinations will create the differences of each voice. A woman's voice and a boy's voice may be at the same pitch, but they do not sound alike. This is because their voices' timbres are different. With the help of VCSD you can adjust the pitch and timbre of any voice, that way you can change age and gender of it.

Voice Morpher graph [Main panel]

In Pitch and Timbre graph, X axis represents the Pitch and Y axis represents the Timbre. To change an input voice, move the Pitch-Timbre pointer within the graph by dragging the pointer or using the arrow keys to move it around. The Pitch value and the Timbre value are displayed at the lower right and upper left corners of the graph respectively.

When the pointer is at the center of the graph, both Pitch value and Timbre value are 100% which mean the voice has not been changed. This is the default percentage of Pitch and Timbre of the original voice when displayed in the Voice Morpher graph. These values are relative on each voice. That's why even if you move the pointer to the same co-ordinate in the Pitch and Timbre graph but the results will totally different when applied on two different input voices.

  • The maximum value of Pitch and Timbre are 200%, the minimum value are 50%.
  • To adjust only the Pitch value, move the Pitch-Timbre pointer horizontally. To adjust only the Timbre value, move the pointer vertically.
  • For a more precise change, click on the pointer, and use the arrow buttons to move it. Each button press equals to one cell move on the graph.
  • To create a younger voice, move the pointer up, or else, move it down.
  • To create a more feminine voice, move the pointer to the right, for a more masculine voice, move the pointer to the left.
Click the Reset button to bring the pointer to its initial position (the center of the Pitch and Timbre graph).
