The following table shows the 24 consonant phonemes found in most dialects of English, plus /x/, whose distribution is more limited. Fortis consonants are always voiceless, aspirated in syllable onset (except in clusters beginning with /s/ or /ʃ/), and sometimes also glottalized to an extent in syllable coda (most likely to occur with /t/, see T-glottalization), while lenis consonants are ...

The word phonology comes from Ancient Greek φωνή, phōnḗ, 'voice, sound', and the suffix -logy (which is from Greek λόγος, lógos, 'word, speech, subject of discussion'). Phonology is typically distinguished from phonetics, which concerns the physical production, acoustic transmission and perception of the sounds or signs of 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. [1] Linguists who specialize in studying the physical properties of speech are phoneticians .
The terms checked vowel and free vowel originated in English phonetics and phonology; they are seldom used for the description of other languages, even though a distinction between vowels that usually have to be followed by a consonant and other vowels is common in most Germanic languages.
The following is the chart of the International Phonetic Alphabet, a standardized system of phonetic symbols devised and maintained by the International Phonetic Association. It is not a complete list of all possible speech sounds in the world's languages, only those about which stand-alone articles exist in this encyclopedia.
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 ...
Many phonetic changes provide the raw ingredients for later phonemic innovations. In Proto-Italic, for example, intervocalic */s/ became *[z]. It was a phonetic change, merely a mild and superficial complication in the phonological system, but when *[z] merged with */r/, the effect on the phonological system was greater.
