This goes on for MegaByte (10^6 bytes), GigaByte (10^9 bytes), TeraByte (10^12 bytes) etc. and MebiByte (2^20 bytes), GibyByte (2^30 bytes), TebiByte (2^40 bytes).
Guttural speech sounds are those with a primary place of articulation near the back of the oral cavity. In some definitions, this is restricted to pharyngeal consonants, but in others includes some velar and uvular consonants. Guttural sounds are typically consonants, but some vowels ' articulations may also be considered guttural in nature.
The English-speaking world is not so familiar with the guttural sounds created in the back of the throat using the uvula but the sounds are common in other languages such as Arabic, Hebrew, German, and Turkish.
