The voiced speech of a typical adult male will have a fundamental frequency from 85 to 155 Hz, and that of a typical adult female from 165 to 255 Hz. Thus, the fundamental frequency of most speech falls below the bottom of the voice frequency band as defined. However, enough of the harmonic series will be … See more A voice frequency (VF) or voice band is the range of audio frequencies used for the transmission of speech. See more The speed of sound at room temperature (20°C) is 343.15 m/s. Using the formula $${\displaystyle Wavelength={\frac {Speed}{Frequency}},}$$ we have: See more In telephony, the usable voice frequency band ranges from approximately 300 to 3400 Hz.
