Note that this is a phonemic chart, a more phonetic analysis is given below

As can be inferred from the chart, there is vowel reduction which is overall not as extensive as Russian but more so than Belorussian.

Long vowels are a result of the coalescence of a vowel (or two vowels) and a glide. Thus the masculine adjective endings -ий and -ый are pronounced iː and ɨː. Due to sound changes concerning the letters л & в, the ToloT and TeleT series also produce long vowels, ie PSl solma > Jsch соўма ['soːmə], cf Russ солома, and PSl melti > Jsch моўть [moːc], cf Russ молоть.
