добавляем этот код себе в userconfig(если нет то создайте userconfig.cfg

alias extoggle exon
alias exon "voice_inputfromfile 1; voice_loopback 1; +voicerecord; alias extoggle exoff"
alias exoff "-voicerecord; voice_inputfromfile 0; voice_loopback 0; alias extoggle exon"
bind "v" "extoggle"[/Table]

Далее:
Вставляем любой звук из выбранного архива который можно скачать отсюда, и добавляем его в папку cstrike и название звука делаем такой voice_input.wav.

теперь заходим в игру и нажимаем букву v и он говорит,можно перебиндить ALT!
Вот код который нужно в userconfig для того что бы говорил нажамая на ALT:

Если хотите поменять, ставьте другой звук меняйте название и всё, это делать можно много раз, даже не выходя из игры, просто сверните её и меняйте))удачи!
