Why the letter «ш» is pronounced like «c»? Is it because of the engine voice or because before a consonant like «к» it must be like that?
"Ш" is never pronounced like "с". It's a problem with the voice.
Хорошо. Спасибо за ответ.
The pronounciation is definitely wrong - please report it. I can't think on an example where «ш» would be pronounced as anything else.
