Parameters for gender adequate voice perception

Project Type: Master/Diploma Thesis
Project Status: Open

 Short Description

The electro-larynx (EL) is a hand-held, battery-driven device. It is one possibility to regain speech for people who had to undergo an operation, where the larynx and the containing vocal folds were removed (typically due to larynx cancer). The device is held against the throat and its vibrations are transmitted through the neck. Then the patient can create speech by modulating the energy in the vocal tract.

We are in the process of designing a new speaking aid that improves significantly on the current state-of-the-art. One important issue is how to design a voice that is perceptually adequate for your gender. Some parameters to use are quite obvious, like fundamental frequency. Changing f0 alone, does not convincingly change a male to a female voice."
