The term "belly speaking" is a playful, informal term often used to refer to:
* Ventriloquism: This is the art of making a voice appear to come from somewhere other than the speaker's mouth, typically using a puppet or other object.
* Speaking from the gut: This idiom means speaking honestly and directly, without filtering your thoughts or feelings. It's a metaphor that implies speaking with authenticity and conviction.
So, while "belly speaking" isn't a formal art term, it's a fun way to describe either ventriloquism or speaking with authenticity.
