A child speech corpus is a speech corpus documenting first-language language acquisition. Such databases are used in the development of computer-assisted language learning systems and the characterization of children's speech at difference ages. [1] Children's speech varies not only by language, but also by region within a language.
The letter for the rear articulation is frequently omitted, in which case a k may usually be assumed. However, some researchers dispute the idea that clicks should be analyzed as doubly articulated, as the traditional transcription implies, and analyze the rear occlusion as solely a part of the airstream mechanism.

The letters s, t, n, l are frequently called 'alveolar', and the language examples below are all alveolar sounds. (The Extended IPA diacritic was devised for speech pathology and is frequently used to mean "alveolarized", as in the labioalveolar sounds [p͇, b͇, m͇, f͇, v͇], where the lower lip contacts the alveolar ridge.)
Typically the position of the sound within a word is considered and targeted. The sound appears in the beginning of the word, middle, or end of the word (initial, medial, or final). Take for example, correction of an "S" sound (lisp). Most likely, a speech language pathologist (SLP) would employ exercises to work on "Sssssss."
Words like alms, balm, calm, Chalmers, qualm, palm and psalm now generally have /ɑː/ in the standard accents, while holm and Holmes are homophones of home(s). Some accents (including many of American English) have reintroduced the /l/ in these words as a spelling pronunciation. The word salmon generally retains a short vowel despite the loss ...
The words, therefore, contain different speech sounds, or phones, transcribed [kʰ] for the aspirated form and [k] for the unaspirated one. These different sounds are nonetheless considered to belong to the same phoneme, because if a speaker used one instead of the other, the meaning of the word would not change: using the aspirated form [kʰ ...
SAMPA was developed in the late 1980s in the European Commission-funded ESPRIT project 2589 "Speech Assessment Methods" (SAM)—hence "SAM Phonetic Alphabet"—in order to facilitate email data exchange and computational processing of transcriptions in phonetics and speech technology. SAMPA is a partial encoding of the IPA. The first version of ...
Aspiration varies with place of articulation. The Spanish voiceless stops /p t k/ have voice onset times (VOTs) of about 5, 10, and 30 milliseconds, and English aspirated /p t k/ have VOTs of about 60, 70, and 80 ms. Voice onset time in Korean has been measured at 20, 25, and 50 ms for /p t k/ and 90, 95, and 125 for /pʰ tʰ kʰ/. [2]
