* Abstract Syntax Tree: This is the most common meaning in computer science, particularly in compilers and interpreters. An AST is a tree-like data structure that represents the syntactic structure of a program. It's a hierarchical representation of the code, showing the relationships between different elements like variables, operators, functions, and control flow structures.
* Automatic Speech Recognition: This is a technology that converts spoken language into text. It is used in various applications like voice assistants, dictation software, and search engines.

* Australian Standard Time: This is the time zone used in most of mainland Australia.
To understand the meaning of AST in a particular context, you need to look at the surrounding information. If you're reading about programming languages, it's likely to refer to an Abstract Syntax Tree. If you're reading about medical tests, it's likely to refer to an Acute Stress Test.
If you can provide more context, I can help you determine the specific meaning of AST.
