Which is greater human speech bandwidth or human hearing bandwidth?
Our results demonstrate that, on average, human listeners can detect the removal of a band of speech between 13 kHz and the upper limit of human hearing (approximately 20 kHz). That humans display sensitivity to this 7-kHz-wide band raises the possibility that it may provide useful information about the speech signal.
What is the bandwidth of actual human speech?
Although speech typically covers frequencies from 30 to 10,000 Hz, most of the energy is in the range from 200 to 3500 Hz.
What is the bandwidth of the voice frequency?
Frequency band
The bandwidth allocated for a single voice-frequency transmission channel is usually 4 kHz, including guard bands, allowing a sampling rate of 8 kHz to be used as the basis of the pulse-code modulation system used for the digital PSTN.
What is the minimum bandwidth required for transmitting human voice?
Voice signals have a rate that ranges from about 4 Kbps when heavily compressed and low quality to 64 Kbps. Audio signals range in rate from 8 Kbps to about 1.3 Mbps for CD quality.
