Voice or voicing is a term used in phonetics and phonology to characterize speech sounds (usually consonants). Speech sounds can be described as either voiceless (otherwise known as unvoiced ) or voiced.
Most investigators accept the definition of language intensity proposed by John Waite Bowers: [1] a quality of language that "indicates the degree to which toward a concept deviates from neutrality." Intensity as a lexical variable in communication studies has generated extensive empirical research.
Sound intensity, also known as acoustic intensity, is defined as the power carried by sound waves per unit area in a direction perpendicular to that area, also called the sound power density and the sound energy flux density. [2] The SI unit of intensity, which includes sound intensity, is the watt per square meter (W/m 2).
For example, no language is known to have a phonemic voicing contrast for vowels with all known vowels canonically voiced. [g] Other positions of the glottis, such as breathy and creaky voice, are used in a number of languages, like Jalapa Mazatec, to contrast phonemes while in other languages, like English, they exist allophonically.
The way a sentence is spoken, however, can change its meaning which is the vocal channel. This channel of language conveys emotions felt by the speaker and gives us as listeners a better idea of the intended meaning. Nuances in this channel are expressed through intonation, intensity, a rhythm which combined for prosody. Usually these channels ...
Another way that lexical prosody is used in the English language is in compound nouns such as "wishbone, mailbox, and blackbird" where the first compound is emphasized. Some suffixes can also affect the ways in which different words are stressed. Take "active" for example. Without the suffix, the lexical emphasis is on "AC".
In speech communication, intelligibility is a measure of how comprehensible speech is in given conditions. Intelligibility is affected by the level (loud but not too loud) and quality of the speech signal, the type and level of background noise, reverberation (some reflections but not too many), and, for speech over communication devices, the properties of the communication system.
The voice, like all acoustic instruments such as the guitar, trumpet, piano, or violin, has its own special chambers for resonating the tone. Once the tone is produced by the vibrating vocal cords, it vibrates in and through the open resonating ducts and chambers.
