Walking in the street I accidently hear what some people who are standing on the other corner of street say. I don't intend to hear and they don't intend me to hear even though they might don't care if I hear it or not.
What is a word for accidentally hearing something as in the above example? Just to make my question more clear, "overhear" and "eavesdrop" are not what I want because they mean "To intentionally hear something without the speaker's awareness or intent."
American Heritage Dictionary 4th Ed. (En-En):
overhear
To hear (speech or someone speaking) without the speaker's awareness or intent.
To hear something without the speaker's awareness or intent.
