Biofeedback is a tool in which bodily functions are electronically monitored and visually displayed to help someone achieve more voluntary control of that function. Usually, it is used to measure functions such as heart rate, blood pressure, or skin temperature. This study was the first time biofeedback was used to visualize speech. Transgender women participants were provided with targets that represented acoustic frequencies typical to cisgender females. They adjusted their speech until their frequencies matched with these targets.

The study, “The Effect of Formant Biofeedback on the Feminization of Voice in Transgender Women,” was published on the website of the Journal of Voice. It may be accessed here.
