An acquaintance of mine was playing with conlanging at one point, and came up with the idea of removing all voiced consonants...

@JeffZeitlin Seems radical (enough). How did it sound? Btw: Removing consonants can be used as an opportunity to add consonants with other features, like removing voiced and adding palatalized.

It turned out not to be extremely radical; it was for a race that didn't have vocal cords. Effectively, the language was simply whispered.

Reminds me of Parseltongue (from Harry Potter) (which is probably not the language your friend created). Because snakes don't have human mouth anatomy, not even lips, it couldn't use voicing or labial consonants.

<p>Probably the best technique is making the language weird by absence. Instead of giving the language weird phonemes, make it lack the most common phonemes. A language with 5 vowels but no /a/, /i/ or /u/. A language with several consonants, but no /p/, /t/, or /k/. Or totally without bilabials. Or with no stops.</p>

This would be my answer. It could be improved by adding a sentence explaining why this is the "best technique": deleting sounds rather than adding them keeps the language easy to pronounce.

A skewed frequency is a perfectly normal property of many linguistic inventories (eg word distribution across a text etc), so it would probably more 'weird' if all phones would be used with an even frequency distribution.

This question has been voted primarily opinion-based. I'd like to note that @jknappen asks for techniques for a goal, and linguistic difference from European languages isn't so opinion based. 'Unnatural' or 'weird', however might be. But although being words that are ultimately opinion-based, I believe most potential respondents know what techniques achieve such an effect.

# Designing a mildly weird phonology

(Asked by: username_0 on 2018-07-18)

I want to design a mildly weird phonology with the following features

* Not particularly difficult to pronounce for speakers of average European languages
* Feeling somewhat unnatural or weird

The weirdness should be noticeable (like the OSV word order in Klingon is). It may include statistical effects (some phones are used more frequent than others thereby producing the effect of weirdness).

What techniques can I use to achieve this effect?
