What characterizes "glib" speech?

Glib speech is characterized by a lack of sincerity and depth. This type of communication often involves smooth, fluent expression that may sound persuasive at first but ultimately lacks substance or authenticity. Individuals who speak in a glib manner may use charming or charismatic language to communicate, yet their words may not reflect genuine emotions or thoughts. This insincerity can make the speaker seem untrustworthy and may suggest that they are more focused on style than on meaningful content or truth.

The other options suggest characteristics that do not align with the definition of glib speech. Thoughtful speech involves careful consideration and depth, emotionally compelling speech evokes genuine feelings, and technical and precise speech focuses on accuracy and clarity. None of these adequately capture the superficiality and lack of sincerity inherent in glib communication.
