Peter John Roach (born 30 June 1943) is a British retired phonetician. He taught at the Universities of Leeds and Reading, and is best known for his work on the pronunciation of British English. 
Peter Roach studied Classics at the Priory Grammar School for Boys, Shrewsbury. At Oxford University (Brasenose College, 1962–1966) he took Classical Honour Moderations before graduating in psychology and philosophy (PPP). He studied teaching English overseas at Manchester University then went on to University College London to take a postgraduate course in phonetics. Later, while a lecturer at the University of Reading, he completed a PhD which was awarded in 1978.
From 1968 to 1978 he was Lecturer in Phonetics at the University of Reading, UK, and for the academic year 1975–1976 was Profesor Encargado de Curso in the Department of English at the University of Seville, Spain, on leave from Reading University. He moved to the University of Leeds in 1978, initially as Senior Lecturer in Phonetics. Subsequently, after moving to the Department of Psychology, he was appointed Professor of Cognitive Psychology. He returned to the University of Reading in 1994 as Professor of Phonetics, later becoming head of the School of Linguistics and Applied Language Studies. He retired in 2004 with the title of Emeritus Professor of Phonetics. 
His best-known publication is English Phonetics and Phonology (C.U.P.). The book was first published in 1983   and is now in its 4th edition (2009). An enhanced e-book edition was published in 2013.  He has been the principal editor of the Cambridge English Pronouncing Dictionary for all editions from the 15th (1997) to the current 18th (2011)   which is also published in CD-ROM format  and an Apple app.  Other books include Phonetics (OUP, 2001), in the series 'Oxford Introductions to Language Study', and Introducing Phonetics (Penguin, 1992). Since the latter became out of print, Roach has made it available in PDF format on the internet as A Little Encyclopaedia of Phonetics.  He has published a large number of research papers and been an invited speaker in fifteen countries.
He has held a number of grants for speech research. He was principal investigator of the ESRC-funded project that resulted in the MARSEC machine-readable version of the Spoken English Corpus,  and was project director of the European-funded project that produced the BABEL multi-language speech corpus.  He was a partner in the European project SPECO that produced a computer-based training system to improve deaf children's speech. 
Daniel Jones was a London-born British phonetician who studied under Paul Passy, professor of phonetics at the École des Hautes Études at the Sorbonne. He was head of the department of phonetics at University College London.
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:
Received Pronunciation (RP) is the accent traditionally regarded as the standard and most prestigious form of spoken British English. For over a century, there has been argument over such questions as the definition of RP, whether it is geographically neutral, how many speakers there are, whether sub-varieties exist, how appropriate a choice it is as a standard and how the accent has changed over time. The name itself is controversial. RP is an accent, so the study of RP is concerned only with matters of pronunciation; other areas relevant to the study of language standards such as vocabulary, grammar, and style are not considered.
Estuary English is an English accent associated with the area along the River Thames and its estuary, including London. Phonetician John C. Wells proposed a definition of Estuary English as "Standard English spoken with the accent of the southeast of England". He views Estuary English as an emerging standard accent of England: an "intermediate" between the 20th-century higher-class non-regional standard accent, Received Pronunciation, and the 20th-century lower-class local London accent, Cockney. There is some debate among linguists as to where Cockney speech ends and Estuary English begins.
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.
The open back rounded vowel, or low back rounded vowel, is a type of vowel sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɒ⟩. It is called Latin turned alpha being a rotated version of Latin alpha. It seems a "turned script a", being a rotated version of "script (cursive) a", which is the variant of a that lacks the extra stroke on top of a "printed a". Latin turned alpha a⟨ɒ⟩ has its linear stroke on the left, whereas Latin alpha a⟨ɑ⟩ has its linear stroke on the right.
The close front unrounded vowel, or high front unrounded vowel, is a type of vowel sound that occurs in most spoken languages, represented in the International Phonetic Alphabet by the symbol i. It is similar to the vowel sound in the English word meet—and often called long-e in American English. Although in English this sound has additional length and is not normally pronounced as a pure vowel, some dialects have been reported to pronounce the phoneme as a pure sound. A pure sound is also heard in many other languages, such as French, in words like chic.
The close back rounded vowel, or high back rounded vowel, is a type of vowel sound used in many spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨u⟩, and the equivalent X-SAMPA symbol is
The close central unrounded vowel, or high central unrounded vowel, is a type of vowel sound used in some languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɨ⟩, namely the lower-case letter i with a horizontal bar. Both the symbol and the sound are commonly referred to as barred i.
The open-mid back rounded vowel, or low-mid back rounded vowel, is a type of vowel sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɔ⟩. The IPA symbol is a turned letter c and both the symbol and the sound are commonly called "open-o". The name open-o represents the sound, in that it is like the sound represented by ⟨o⟩, the close-mid back rounded vowel, except it is more open. It also represents the symbol, which can be remembered as an o which has been "opened" by removing part of the closed circular shape.
The open-mid front unrounded vowel, or low-mid front 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 a Latinized variant of the Greek lowercase epsilon, ⟨ɛ⟩.
The near-close front unrounded vowel, or near-high front 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 ⟨ɪ⟩, i.e. a small capital version of the Latin letter i. The International Phonetic Association advises serifs on the symbol's ends. Some sans-serif fonts do meet this typographic specification. Prior to 1989, there was an alternate symbol for this sound: ⟨ɩ⟩, the use of which is no longer sanctioned by the IPA. Despite that, some modern writings still use it.
John Christopher Wells is a British phonetician and Esperantist. Wells is a professor emeritus at University College London, where until his retirement in 2006 he held the departmental chair in phonetics. He is known for his work on the Esperanto language and his invention of the standard lexical sets and the X-SAMPA phonetic script system.
A pronunciation respelling for English is a notation used to convey the pronunciation of words in the English language, which do not have a phonemic orthography.
The mid front unrounded vowel is a type of vowel sound that is used in some spoken languages. There is no dedicated symbol in the International Phonetic Alphabet that represents the exact mid front unrounded vowel between close-mid and open-mid, but it is normally written ⟨e⟩. If precision is required, diacritics may be used, such as ⟨e̞⟩ or ⟨ɛ̝⟩. In Sinology and Koreanology, ⟨ᴇ⟩ is sometimes used, for example in the Zhengzhang Shangfang reconstructions.
Speech tempo is a measure of the number of speech units of a given type produced within a given amount of time. Speech tempo is believed to vary within the speech of one person according to contextual and emotional factors, between speakers and also between different languages and dialects. However, there are many problems involved in investigating this variance scientifically.
The Spoken English Corpus (SEC) is a speech corpus collection of recordings of spoken British English compiled during 1984–7. The corpus manual can be found on ICAME.
Jack Windsor Lewis was a British phonetician. He is best known for his work on the phonetics of English and the teaching of English pronunciation to foreign learners. His blog postings on English phonetics and phoneticians are prolific and widely read.
