There are many examples for allophones in languages other than English. Typically, languages with a small phoneme inventory allow for quite a lot of allophonic variation: examples are Hawaiian and Pirahã. Here are some examples (the links of language names go to the specific article or subsection on the phenomenon): Consonant allophones
For example, chain shifts such as the Great Vowel Shift (in which nearly all of the vowels of the English language changed) or the allophonic differentiation of /s/, originally *[s], into [s z ʃ ʒ ʂ ʐ θ χ χʷ h], do not qualify as phonological change as long as all of the phones remain in complementary distribution.
A related process is coarticulation in which one segment influences another to produce an allophonic variation, such as vowels becoming nasalized before nasal consonants (/n, m, ŋ/) when the soft palate (velum) opens prematurely or /b/ becoming labialized as in "boot" [bʷuːt̚] or "ball" [bʷɔːɫ] in some accents.
The variation may be conditioned by the phonological, morphological, and/or syntactic environment in which the morpheme finds itself. Alternations provide linguists with data that allow them to determine the allophones and allomorphs of a language's phonemes and morphemes and to develop analyses determining the distribution of those allophones ...
Specific allophonic variations, and the particular correspondences between allophones (realizations of speech sound) and phonemes (underlying perceptions of speech sound) can vary even within languages. For example, speakers of Quebec French often express voiceless alveolar stops (/t/) as an affricate.
A merger between two segments can also occur between word boundaries, an example being the phrase got ya /ˈɡɒt jə/ being pronounced like gotcha /ˈɡɒtʃə/. Most cases of fusion lead to allophonic variation, though some sequences of segments may lead to wholly distinct phonemes.
There is significant allophonic variation in /əʉ/, including a backed allophone [ɔʊ] before a word-final or preconsonantal /l/. The first part of this allophone is in the same position as /ɔ/, but [ɔʊ] differs from it in that it possesses an additional closing glide, which also makes it longer than /ɔ/.
An example in American English is that the sound spelled with the symbol t is usually articulated with a glottal stop [ʔ] (or a similar glottalized sound) in the word cat, an alveolar flap [ɾ] in dating, an alveolar plosive [t] in stick, and an aspirated alveolar plosive [tʰ] in tie; however, American speakers perceive or "hear" all of these ...
