The synthetic voices available in the voice bank have been developed using different sources. Some of them have been directly donated by people and generated using personalization techniques. Special thanks to them for making available their voices to those who need them. 

Some other voices come from professional recordings available at repositories. They have been trained from scratch. Those voices are listed here.
