I've lately made a post on this site about a langauge I've created, this post is just a follow-up. Read the previous one if you want some background: http://linguistforum.com/linguist's-lounge/so-i've-created-a-very-functional-language-with-only-32-words/Here is the next level of sophistication, the fifth, of Truespeak pronunciation.
XXXX0 - The consonant at the beginning is pronounced with the lips stretched. It's a subtle difference, but a noticable one.
XXXX1 - The opening consonant is pronounced with the lips puckered.
XXX0X - The opening consonant is "soft", meaning that no air is pushed out with the sound (it's a little difficult to explain how this works with IPA or any equivalent of which I know).
XXX1X - The opening consonant is "heavy", meaning that as the sound comes out, so does a gust of air.
The best way I can explain this is that the "force" given to the consonant is from the inside mouth in XXX0X's case, and with the lungs in XXX1X's case.
XX0XX - Similar to XXXX0, only with the finishing consonant.
XX1XX - Similar to XXXX1, only with the finishing consonant.
X0XXX - (Lack of X1XXX's effect, see below.)
X1XXX - The finishing consonant has a z before it if it is voiced, and an s if not (think "ak" vs "ask").
0XXXX - (Lack of 1XXXX's effect, see below.)
1XXXX - If the first particle in the syllable is a 0XXXX particle, then the opening consonant becomes the fricative equivalent of what would normally be a 1XXXX particle (t becomes ths, th becomes thsh; m, r, h, and rh are special cases that become st, zd, sht and zhd respectively). If the first particle in the syllable is a 1XXXX particle, then the opening consonant gains the fricative equivalent of what would normally be a 1XXXX particle (ts becomes tths, ksh becomes kkhsh; s, z, sh, and zh are special cases that become sk, zg, shk and zhg respectively).
Another thing worth mentioning is the fact that when speaking, one can "start" the syllable from the vowel to imply that the syllable is an exclamation. An example would be "egh", which could be interpreted as "Well!", or "What joy!" rather than "happiness/love" ("edh" can be "Hello!"; "o" can resemble a question mark in many situations; "av" can mean "Oh, alright then." [understanding]; "awv" can be "Excuse me?/I don't understand."; et cetera, et cetera).
