The term phonation has slightly different meanings depending on the subfield of phonetics. Among some phoneticians, phonation is the process by which the vocal folds produce certain sounds through quasi-periodic vibration. This is the definition used among those who study laryngeal anatomy and physiology and speech production in general.
To produce sounds that people can interpret as spoken words, the movement of air must pass through the vocal folds, up through the throat and, into the mouth or nose to then leave the body. Different sounds are formed by different positions of the mouth—or, as linguists call it, "the oral cavity" (to distinguish it from the nasal cavity).
However speech production can occur without the use of the lungs and glottis in alaryngeal speech by using the upper parts of the vocal tract. An example of such alaryngeal speech is Donald Duck talk. [5] The vocal production of speech may be associated with the production of hand gestures that act to enhance the comprehensibility of what is ...
These movements disrupt and modify an airstream which results in a sound wave. The modification is done by the articulators, with different places and manners of articulation producing different acoustic results. For example, the words tack and sack both begin with alveolar sounds in English, but differ in how far the tongue is from the ...
See buccal speech. [1] after a laryngectomy, the esophagus may be used (notated {Œ} for simple esophageal speech, {Ю} for tracheo-esophageal speech in VoQS, and notated {И} for electrolaryngeal speech). See esophageal speech. [2] the pharynx, and replacing the glottis using the tongue and the upper alveolus, the palate, or the pharyngeal wall.
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.
The articulation of voice enhances the resonance of speech and enables people to speak intelligibly. [1] Speaking at a moderate pace and using clear pronunciation improves the phonation of sounds. The term " phonation " means the process to produce intelligible sounds for the correct interpretation of speech. [ 2 ]
The difference is best illustrated by a rough example. The English word nods is made up of a sequence of phonemes, represented symbolically as /nɒdz/, or the sequence of /n/, /ɒ/, /d/, and /z/. Each symbol is an abstract representation of a phoneme. That awareness is an inherent part of speakers' mental grammar that allows them to recognise ...
