Speakers vary their speed of speaking according to contextual and physical factors. A typical speaking rate for English is 4 syllables per second, [5] but in different emotional or social contexts the rate may vary, one study reporting a range between 3.3 and 5.9 syl/sec, [6] Another study found significant differences in speaking rate between story-telling and taking part in an interview.
An example of an agglutinative language, the average rate of Turkish speech is reported to be about 220 syllables per minute. When the time spent for the silent parts of speech are removed, the so-called average articulation rate reaches 310 syllables per minute. [21] The average number of syllables per (written) word has been measured as 2.6.
While one might expect speeding up to reduce comprehension, Herb Friedman says that "Experiments have shown that the brain works most efficiently if the information rate through the ears—via speech—is the 'average' reading rate, which is about 200–300 wpm (words per minute), yet the average rate of speech is in the neighborhood of 100 ...
The voiced speech of a typical adult male will have a fundamental frequency from 90 to 155 Hz, and that of a typical adult female from 165 to 255 Hz. [3] Thus, the fundamental frequency of most speech falls below the bottom of the voice frequency band as defined.
For example, for a typical steel alloy, K = 170 GPa, G = 80 GPa and p = 7700 kg/m 3, yielding a compressional speed c solid,p of 6,000 m/s. [11] This is in reasonable agreement with c solid,p measured experimentally at 5,930 m/s for a (possibly different) type of steel. [21] The shear speed c solid,s is estimated at 3,200 m/s using the same ...

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.
