Voices

I log onto Minecraft (PC) when i click on any of the starting buttons a voice says 'click' and it does that whenever i click on any button in the menu. When i go onto a single player or a server i walk around and as soon as i walk on the block it will say it in a really annoying voice. I solved the problem of whenever i walk on something it says it by turning blocks off but it also sings a song like a minecraft song but humming. I would really know how to fix this
Thanks
