Aperiodic sound sources are the turbulent noise of fricative consonants and the short-noise burst of plosive releases produced in the oral cavity. Voicing is a common period sound source in spoken language and is related to how closely the vocal cords are placed together. In English there are only two possibilities, voiced and unvoiced. Voicing ...
In phonetics, the basis of articulation, also known as articulatory setting, [1] [2] is the default position or standard settings of a speaker's organs of articulation when ready to speak. Different languages each have their own basis of articulation, which means that native speakers will share a certain position of tongue, lips, jaw, possibly ...
In articulatory phonetics, the place of articulation (also point of articulation) of a consonant is an approximate location along the vocal tract where its production occurs. [ 1 ] : 10 It is a point where a constriction is made between an active and a passive articulator.
Examples include English /w/ and /r/. In some languages, such as Spanish, there are sounds that seem to fall between fricative and approximant. One use of the word semivowel, sometimes called a glide, is a type of approximant, pronounced like a vowel but with the tongue closer to the roof of the mouth, so that there is slight turbulence.
Acoustic phonetics is a subfield of phonetics, which deals with acoustic aspects of speech sounds. Acoustic phonetics investigates time domain features such as the mean squared amplitude of a waveform, its duration, its fundamental frequency, or frequency domain features such as the frequency spectrum, or even combined spectrotemporal features and the relationship of these properties to other ...
In English, an audible intake of breath, [hːː↓], or an indrawn consonant such as [tʰ↓] or [p͡t↓] is used in a conversation to indicate that someone is about to speak or is preparing to continue speaking. [7] In some languages, such as Finnish and Amharic, entire phrases may be uttered with an ingressive airstream. (See ingressive sound.)
In articulatory phonetics, the specific "place of articulation" or "point of articulation" of a consonant is that point of contact where an obstruction occurs in the vocal tract between an active (moving) articulator (typically some part of the tongue) and a passive (stationary) articulator (typically some part of the roof of the mouth).
Velarization is the raising of the back of the tongue toward the velum, as in the English "dark" L, [lˠ]. Pharyngealization is a constriction in the throat (pharynx) and is found in the Arabic "emphatic" consonants such as [sˤ]. Glottalization involves action of the glottis in addition to the primary articulation of the consonant.
