I am unable to hear the difference with other vowels. It is verry 
possible this it's really an improvement in other cases but really in 
these words the 'l' sound is a bit distracting for me. It's very 
difficult to judge because now I've found out e.g. in the word
alt
the 'l' sound fine at the maximum speed.

When 'z' is not followed by a vowel it's sometimes getting stressed too 
much I think e.g. in the word
zrak
For the letter 's' the change does not sound stressed too much at high 
speeds but at lower speeds e.g. around 200 it is also noticeable e.g. in 
the word
strana
This is very minor perhaps you can leave 's' this way if no one 
identifies it as a problem.

More experimenting with c shouws that c is okay but when it's getting 
shortened at high speeds the sound changes rapidly. While hearing the 
letter 'c' alone continuously for a little while I have a feeling it's 
turning into something close to letter 'ť'. I am not sure whether it'is 
also possible to affect how speed increase affects voicing. If it 
changes constantly and there is nothing to tune in this case I think you 
may leave it this way too.
