Phonetics

Phonetics (pronounced /fəˈnɛtɪks/, from the Greek: φωνή, phōnē, 'sound, voice') is a branch of linguistics that comprises the study of the sounds of human speech, or—in the case of sign languages—the equivalent aspects of sign. It is concerned with the physical properties of speech sounds or signs (phones): their physiological production, acoustic properties, auditory perception, and neurophysiological status. Phonology, on the other hand, is concerned with the abstract, grammatical characterization of systems of sounds or signs.

The field of phonetics is a multilayered subject of linguistics that focuses on speech. In the case of oral languages there are three basic areas of study:

International Phonetic Alphabet

The International Phonetic Alphabet (unofficially—though commonly—abbreviated IPA) is an alphabetic system of phonetic notation based primarily on the Latin alphabet. It was devised by the International Phonetic Association as a standardized representation of the sounds of oral language. The IPA is used by lexicographers, foreign language students and teachers, linguists, speech-language pathologists, singers, actors, constructed language creators, and translators.

The IPA is designed to represent only those qualities of speech that are part of oral language: phones, phonemes, intonation, and the separation of words and syllables. To represent additional qualities of speech, such as tooth gnashing, lisping, and sounds made with a cleft palate, an extended set of symbols called the Extensions to the International Phonetic Alphabet may be used.

IPA symbols are composed of one or more elements of two basic types, letters and diacritics. For example, the sound of the English letter ⟨t⟩ may be transcribed in IPA with a single letter, [t], or with a letter plus diacritics, [t̺ʰ], depending on how precise one wishes to be. Often, slashes are used to signal broad or phonemic transcription; thus, /t/ is less specific than, and could refer to, either [t̺ʰ] or [t], depending on the context and language.

English as a second or foreign language

English as a second or foreign language is the use of English by speakers with different native languages. Instruction for English-language learners may be known as English as a second language (ESL), English as a foreign language (EFL), English as an additional language (EAL), or English for speakers of other languages (ESOL).

English as a second language (ESL) is often used for non-native English speakers learning English in a country where English is commonly spoken. English as a foreign language (EFL) is used for non-native English speakers learning English in a country where English is not commonly spoken. The term ESL has been misinterpreted by some to indicate that English would be of secondary importance. However, it simply refers to the order in which the language was learned, consistent with the linguistic terminology of second-language acquisition. The term ESL can be a misnomer for some students who have learned several languages before learning English. The terms English Language Learners (ELL), and more recently English Learners (EL), have been used instead, and the students’ home language and cultures are considered important.
