Phonetic space is the range of sounds that can be made by an individual. [1] There is some controversy over whether an individual's phonetic space is language dependent, or if there exists some common, innate, phonetic space across languages. [2]
Phonetic Space is a concept pioneered by Martin Joos in 1948 [3] and developed by Gordon E. Peterson in 1951 [4] and Noam Chomsky in 1968. [5] Chomsky developed the idea that phonetic space is universal and every human is born with a discrete phonetic space. [5] The most cited rebuttal of Chomsky's proposal of a universal and discrete phonetic space is an article by Port and Leary titled, "Against Formal Phonology". [6] Applications of phonetic space include interlanguage phonetic comparison and phonological analysis. [2]
A definition of phonetic space is not agreed upon, the concept varying in use and meaning depending on the author in question. Some similarities and constants can, however, be drawn. One thing that is known, phonetic space is universal; every human that uses verbal communication obtains a discrete phonetic space. [1] [2] [5] This space is the distribution of vowels perceived by the speaker. The recognition of words, and specifically the vowels within these words, is achieved by noting a perceived difference between one sound and another. The act of comparing these competing sounds and categorizing them within the mind is the creation of a phonetic space. [7] The identity of each sound is a conglomerate of ideas and concepts composed of categories such as: VOT (Voice Onset Time), Amplitude Rise-Time, Formant Frequency, Bandwidth, Formant Transition, and Energy-Density Maximum. Not all of these categories are used for every sound, however in building an individual phonetic space, the aforementioned attributes are oftentimes integral to the differentiation process used by the mind to successfully distinguish between any two competing sounds. [5] Based on these ideas, the Vowel Quadrilateral is used to show what the realization of these basic would look like, and helps to visually conceptualize the separation of competing phonetic space that occurs within the human mind.
In 2005, Robert F. Port and Adam P. Leary published an argument against the existence of a fixed phonetic inventory. They presented the idea of a phonetic space as unrealistic in terms of the broadness of languages present and more specifically that languages are not consistent in distinctness, discreteness, or temporal patterns, even within the same language. [6] They argue that in order for a formal system to exist, it must have rules, and therefore each "phonetic atom" - in this case, all the phonetic sounds in the universe - "must be static and discretely different from each other," which means there can be no inconsistency in how each sound is produced. They argue that this is unrealistic because speakers of the same language often speak differently in that the intonations of sounds and stresses on syllables depend on each person's style of speaking, not necessarily their accent.
Port and Leary claim that phonetics is filled with many asymmetries. How we understand the phonetic space to look like comes from the idea that the dimensions of the space include Voicing, Height, and Nasal, and the variations of these dimensions help produce the many sounds of language. Port and Leary argue that not all phonetic properties can be combined, however, such as vowel height and backness, and therefore, the rules are asymmetric in that it is unknown what properties can exist together in one sound.
In regards to the concept of the phonetic space, Port and Leary essentially argue that, contrary to the research of Chomsky and Halle, there are too many inconsistencies and difficulties concerned with the existence of a phonetic space and that while their perspective is not widely accepted by other linguists, they contribute valid points to the idea that the infinite number of sounds cannot co-exist perfectly with a set of rules in one space. [6]
Phonetic space is rarely touched upon in linguistics, and therefore little research has been done on the topic, however, there are a few things of note regarding the subject: The idea of phonetic space could not have developed until we had a working definition of phonetics and had a way to place sound in space. While Grassmann's development of linear algebra set us on the conceptual path to placing values in space, [8] [ circular reference ] it was C. G. Kratzenstein who first published detailed methods to synthesize speech in the 1700s. "Although when his principal phonetic work, was published in 1781 and 1782 there was no clear understanding of acoustic resonance, his accomplishment – via trial and error – was remarkable and contributed to accumulating "existence proofs" that speech could be understood in physical and physiological terms." [9]
While first mentioned in the 1700s, the idea was largely ignored until the 1940s when the term was more officially coined by Martin Joos, an American linguist and professor of German. Joos contributed much to the realm of phonetics and phonology, writing the monograph that helped linguists come to a more unified theory regarding acoustics in phonetics. [10] [ circular reference ] [11] The concept would later be expanded on by Gordon E. Peterson [12] in his essay, ‘The Phonetic Value of Vowels’. Along with these contributions, Marshall McLuhan could be mentioned as well, as he was the one to truly consider acoustic space, which is very similar to phonetic space. Though not exactly the same, as acoustic space refers more to the environment that allows for the sound, while phonetic space is more niche, in that it is in reference to the space between sounds. [13] [ circular reference ] [14] On a surface level they may not seem related, but it is worth the mention even if nothing is directly attributed to McLuhan.
Martin Joos was an American linguist who was most commonly known for his study on language formality. [15] Though Joos didn't solely study phonetic space, he contributed to the field of Acoustic Phonetics through his journal entry Acoustic Phonetics and Readings in Linguistics.
Gordon E. Peterson was an American linguist whose field of study varied from acoustic analysis to phonemic theory and automatic speech recognition. [16] Though Peterson didn't explicitly study phonetic space, in his study of phonetic value, he concluded that the vowel diagram that linguists typically use is a two-dimensional representation of the vowels in the phonetic space, which is multi-dimensional. [17]
Noam Chomsky is a prominent American linguist who pioneered the idea of an innate universal grammar, which also ties into his idea that phonetic space is also universally innate. [18] [19]
In 2010, a study on Phonetic Space was done to determine if phonetic spaces do exist and differ speaker to speaker. [20] Three groups of participants were tested: those who were born and raised in China, those who moved from China at an early age and Americans who have learned Chinese later in life. Subjects were recorded saying various sounds and analyzed thorough Praat, a computer software that measures sounds into Hz. The various frequencies are grouped into Formants which correlate to certain sounds in the proposed phonetic space. The recorded values for the sounds of heritage speakers and non heritage speakers differed greatly. The averages show that the phonetic space, or values of sound, differ between the three groups.
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.
In speech science and phonetics, a formant is the broad spectral maximum that results from an acoustic resonance of the human vocal tract. In acoustics, a formant is usually defined as a broad peak, or local maximum, in the spectrum. For harmonic sounds, with this definition, the formant frequency is sometimes taken as that of the harmonic that is most augmented by a resonance. The difference between these two definitions resides in whether "formants" characterise the production mechanisms of a sound or the produced sound itself. In practice, the frequency of a spectral peak differs slightly from the associated resonance frequency, except when, by luck, harmonics are aligned with the resonance frequency.
In phonology and linguistics, a phoneme is a unit of phone that can distinguish one word from another in a particular language.
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 or dialects 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:
A vowel is a syllabic speech sound pronounced without any stricture in the vocal tract. Vowels are one of the two principal classes of speech sounds, the other being the consonant. Vowels vary in quality, in loudness and also in quantity (length). They are usually voiced and are closely involved in prosodic variation such as tone, intonation and stress.
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⟩.
Phonetic transcription is the visual representation of speech sounds by means of symbols. The most common type of phonetic transcription uses a phonetic alphabet, such as the International Phonetic Alphabet.
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 branches of phonetics, and to abstract linguistic concepts such as phonemes, phrases, or utterances.
The open-mid central rounded vowel, or low-mid central rounded vowel, is a vowel sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɞ⟩, and the equivalent X-SAMPA symbol is 3\
. The symbol is called closed reversed epsilon. It was added to the IPA in 1993; before that, this vowel was transcribed ⟨ɔ̈⟩.
The phonology of Vietnamese features 19 consonant phonemes, with 5 additional consonant phonemes used in Vietnamese's Southern dialect, and 4 exclusive to the Northern dialect. Vietnamese also has 14 vowel nuclei, and 6 tones that are integral to the interpretation of the language. Older interpretations of Vietnamese tones differentiated between "sharp" and "heavy" entering and departing tones. This article is a technical description of the sound system of the Vietnamese language, including phonetics and phonology. Two main varieties of Vietnamese, Hanoi and Saigon, which are slightly different to each other, are described below.
In phonetics, an r-colored or rhotic vowel is a vowel that is modified in a way that results in a lowering in frequency of the third formant. R-colored vowels can be articulated in various ways: the tip or blade of the tongue may be turned up during at least part of the articulation of the vowel or the back of the tongue may be bunched. In addition, the vocal tract may often be constricted in the region of the epiglottis.
In linguistics, a segment is "any discrete unit that can be identified, either physically or auditorily, in the stream of speech". The term is most used in phonetics and phonology to refer to the smallest elements in a language, and this usage can be synonymous with the term phone.
Kenneth Noble Stevens was the Clarence J. LeBel Professor of Electrical Engineering and Computer Science, and professor of health sciences and technology at the research laboratory of electronics at MIT. Stevens was head of the speech communication group in MIT's research laboratory of electronics (RLE), and was one of the world's leading scientists in acoustic phonetics.
A vowel diagram or vowel chart is a schematic arrangement of the vowels. Depending on the particular language being discussed, it can take the form of a triangle or a quadrilateral. Vertical position on the diagram denotes the vowel closeness, with close vowels at the top of the diagram, and horizontal position denotes the vowel backness, with front vowels at the left of the diagram. Vowels are unique in that their main features do not contain differences in voicing, manner, or place (articulators). Vowels differ only in the position of the tongue when voiced. The tongue moves vertically and horizontally within the oral cavity. Vowels are produced with at least a part of their vocal tract obstructed.
Japanese has one liquid phoneme, realized usually as an apico-alveolar tap and sometimes as an alveolar lateral approximant. English has two: rhotic and lateral, with varying phonetic realizations centered on the postalveolar approximant and on the alveolar lateral approximant, respectively. Japanese speakers who learn English as a second language later than childhood often have difficulty in hearing and producing the and of English accurately.
A phonological rule is a formal way of expressing a systematic phonological or morphophonological process or diachronic sound change in language. Phonological rules are commonly used in generative phonology as a notation to capture sound-related operations and computations the human brain performs when producing or comprehending spoken language. They may use phonetic notation or distinctive features or both.
Martin Joos (1907–1978) was an American linguist and professor of German. He spent most of his career at the University of Wisconsin–Madison, and also served at the University of Toronto and as a visiting scholar at the University of Alberta, the University of Belgrade, and the University of Edinburgh. During World War II, Joos was a cryptologist for the US Signal Security Agency. The War Department honored him with a Distinguished Service citation in recognition of his work developing communication systems. After the war he returned to the University of Wisconsin, eventually serving as the chairman of the Department of German.
The quantal theory of speech is a phonetic answer to one of the fundamental questions of phonology, specifically: if each language community is free to arbitrarily select a system of phonemes or segments, then why are the phoneme inventories of different languages so similar? For example, almost all languages have the stop consonants /p/, /t/, /k/, and almost all have the vowels /a/, /i/, and /u/. Other phonemes differ considerably among languages, but not nearly as much as they would if each language were free to choose arbitrarily.
Osamu Fujimura 藤村靖 was a Japanese physicist, phonetician and linguist, recognized as one of the pioneers of speech science. Fujimura was also known for his influential work in the diverse field of speech-related studies including acoustics, phonetics/phonology, instrumentation techniques, speech production mechanisms, and computational/theoretical linguistics.
