Another voiceover issue.

Sorry about all the posts, I am just new to Mac and am having a few issues. Right now I am having an issue where I hear a bloop every few seconds, and I have no idea what it is. It started right after I opened the weather app. Restarting the computer is the only thing that seems to fix this, but what is the bloop? This is the second time this has happened, the first time it started after I installed an app.
