Speed is measured in distance per unit time. Like, meters per second. The speed of sound is about 340 meters per second.
Wavelength is measured in length, it is not a measure of speed.
Human voice frequency is generally 20 Hz (very very low) to 20 kHz (very high). The wavelengths are about 17 meters to 1.7 cm. The average is about 1000 Hz, with a wavelenth of 34 cm.

A wavelength is NOT a speed. If you're wondering about how many wave(length)s you get per unit time, that would be the dominant frequency of speech (I think it's around 2000 hertz.). If you want to know the wavelength of a 2000 hertz sound divide the speed of sound, about 1100 ft per second by the sound's frequency.
