Approximants are speech sounds that involve the articulators approaching each other but not narrowly enough nor with enough articulatory precision to create turbulent airflow. Therefore, approximants fall between fricatives, which do produce a turbulent airstream, and vowels, which produce no turbulence. This class is composed of sounds like and semivowels like and, as well as lateral approximants like.
Liquids are a class of consonants that consists of rhotics and voiced lateral approximants, sometimes described as "r-like sounds" and "l-like sounds". The word liquid seems to be a calque of the Ancient Greek word ὑγρός initially used by grammarian Dionysius Thrax to describe Greek sonorants.
Phonetics is a branch of linguistics that studies how humans produce and perceive sounds, or in the case of sign languages, the equivalent aspects of sign. Linguists who specialize in studying the physical properties of speech are phoneticians. The field of phonetics is traditionally divided into three sub-disciplines based on the research questions involved such as how humans plan and execute movements to produce speech, how various movements affect the properties of the resulting sound, or how humans convert sound waves to linguistic information. Traditionally, the minimal linguistic unit of phonetics is the phone—a speech sound in a language which differs from the phonological unit of phoneme; the phoneme is an abstract categorization of phones, and it is also defined as the smallest unit that discerns meaning between sounds in any given language.
Phonology is the branch of linguistics that studies how languages systematically organize their phones or, for sign languages, their constituent parts of signs. The term can also refer specifically to the sound or sign system of a particular language variety. At one time, the study of phonology related only to the study of the systems of phonemes in spoken languages, but may now relate to any linguistic analysis either:
An affricate is a consonant that begins as a stop and releases as a fricative, generally with the same place of articulation. It is often difficult to decide if a stop and fricative form a single phoneme or a consonant pair. English has two affricate phonemes, and, often spelled ch and j, respectively.
The glottal stop or glottal plosive is a type of consonantal sound used in many spoken languages, produced by obstructing airflow in the vocal tract or, more precisely, the glottis. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʔ⟩.
Klas Bernhard Johannes Karlgren was a Swedish sinologist and linguist who pioneered the study of Chinese historical phonology using modern comparative methods. In the early 20th century, Karlgren conducted large surveys of the varieties of Chinese and studied historical information on rhyming in ancient Chinese poetry, then used them to create the first ever complete reconstructions of what are now called Middle Chinese and Old Chinese.
The voiceless alveolar lateral fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents voiceless dental, alveolar, and postalveolar lateral fricatives is, and the equivalent X-SAMPA symbol is K.
The open front unrounded vowel, or low front unrounded vowel, is a type of vowel sound used in some spoken languages. It is one of the eight primary cardinal vowels, not directly intended to correspond to a vowel sound of a specific language but rather to serve as a fundamental reference point in a phonetic measuring system.
The open back unrounded vowel, or low back unrounded vowel, is a type of vowel sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɑ⟩, and the equivalent X-SAMPA symbol is A. The letter ⟨ɑ⟩ is called script a because it lacks the extra hook on top of a printed letter a, which corresponds to a different vowel, the open front unrounded vowel. Script a, which has its linear stroke on the bottom right, should not be confused with turned script a,, which has its linear stroke on the top left and corresponds to a rounded version of this vowel, the open back rounded vowel.
Praat is a free computer software package for speech analysis in phonetics. It was designed, and continues to be developed, by Paul Boersma and David Weenink of the University of Amsterdam. It can run on a wide range of operating systems, including various versions of Unix, Linux, Mac and Microsoft Windows. The program supports speech synthesis, including articulatory synthesis. Its logo depicts a mouth over an ear.

She held the Chair of Linguistics at the University of Oxford from 2007 until her retirement in 2022; she was a Fellow of Somerville College, Oxford. Her main research interests are in phonology, phonetics, historical linguistics, psycholinguistics, and neurolinguistics.
Linguistics is the scientific study of language. Linguistics is based on a theoretical as well as a descriptive study of language and is also interlinked with the applied fields of language studies and language learning, which entails the study of specific languages. Before the 20th century, linguistics evolved in conjunction with literary study and did not exclusively employ scientific methods.
