In terms of vocal quality:

* High pitch: A high-pitched voice can sometimes be perceived as thin, particularly if it lacks projection or resonance.
* Limited vocal range: A voice with a narrow range might sound thin because it lacks the ability to explore different pitches and tones.
In terms of writing or speaking style:
* Lack of conviction: A "thin voice" might be used to describe writing or speech that lacks passion, authority, or persuasiveness.
