Frequency band for transmitting speech
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. It is for this reason that the ultra low frequency band of the electromagnetic spectrum between … See more • Formant • Hearing (sense) See more Speech Transmission Index (STI) is a measure of speech transmission quality. The absolute measurement of speech intelligibility is a complex science. The STI measures some physical characteristics of a transmission channel (a room, electro-acoustic equipment, telephone line, etc.), and expresses the ability of the channel to carry across the characteristics of a speech signal. STI is a well-established objective measurement predictor of how the characteristics of t…
