"A woman who utters such depressing and disgusting sounds has no right to be anywhere—no right to live. Remember that you are a human being with a soul and the divine gift of articulate speech: that your native language is the language of Shakespeare and Milton and The Bible; and don't sit there crooning like a bilious pigeon."
People could all interpret this differently but to me it means that you are not worthy of living when you say such mean/depressing things. And that you should realize you are worthy and that you have the gift of speech so use it nicely.
