The Human Voice. The human vocal tract is a pipe that extends about 17 cm from the lips to the vocal folds (also called ''vocal cords") near the middle of your throat. The vocal folds behave rather like the reed of a clarinet, and the vocal tract acts like a stopped pipe. Estimate the first three standing-wave frequencies of the vocal tract. Use v = 344 m/s.
