title_body: Are there conlangs using constructed sounds? Usually, constructed languages of all kind (naturalistic or not) draw their sounds from existing natural languages.
  
  Are there conlangs with constructed sounds, i.e., sounds that do not occur in natural languages (or are at least very rare in natural languages)?
upvoted_answer: Click consonants are rare in natlangs, but rather popular in conlangs, though despite this, given the existence of things like !Xóõ reality is stranger than most fiction in this specific regard. Language-game/conlang(?) turned actual spoken register Damin had several phonemes not seen in (other?) natural languages, such as an ingressive glotally interrupted unvoiced lateral fricative /ɬ↓ʔ/, an egressively released bilabial click /ʘ↑/ and stuttered bilabial trill /ʙ\ʙ/. 
  
  Searching for the various hypothetical combinations as well as ext-IPA sounds on google turns up a fair few instances of conlangs using sounds such as percussives, implosive fricatives, velopharyngeal and nareal fricatives, etc.
  
  Outside of these humanly-possible, but non-attested outside of disordered speech phonemes, some languages made up for non-humans include sounds that are impossible for humans to make, such as this one spoken by a race of giants, including a special type of whistle-like sounds, or this one made for creatures with bird-like anatomy, differentiating between 4 different types of contraction of muscles in the throat overlaid with 5 different pitch contours.
