My question is about the voiceless affricate /tʃ/ ( CHair, maTCH, baTCH, strucTure) as it is used in ENGLISH:
English has two affricates: the /tʃ/ in "chair" and the /dʒ/ in "jar".
The /tʃ/ is a voiceless affricate.
My question is, since this is voiceless, does it follow the same rules of aspiration as voiceless stops in English? That is, like /p/, /t/, /k/?
/p/, /t/ and /k/ are usually aspirated when at the beginning of a word(except when preceded by s in the same syllable) and at the onset of a stressed syllable. Does the same hold true for /tʃ/?
So the /tʃ/ sound in "chair" is aspirated whereas in "catch", it is not? Or is it, but a little less in magnitude?
