 ## Overview
 
 Fish Audio models support 64+ emotional expressions and voice styles that can be controlled through text markers in your input. Add natural pauses, laughter, and other human-like elements to make speech more engaging and realistic.
 
 <Tip>
-The `(parenthesis)` syntax on this page applies to the S1 model. S2 uses `[bracket]` syntax with natural language descriptions and is not limited to a fixed set of tags. See the [Models Overview](/developer-guide/models-pricing/models-overview#s2-natural-language-control) for details.
+  This page shows S2 usage with `[bracket]` cues. If you use S1, you must use
+  markers wrapped in parentheses. See the [Models
+  Overview](/developer-guide/models-pricing/models-overview#s2-natural-language-control)
+  for details.
 </Tip>
 
 ## How It Works
 
-Simply wrap emotion tags in parentheses within your text:
+Add emotional or stylistic cues in square brackets within your text:
 
-```
-(happy) What a beautiful day!
-(sad) I'm sorry to hear that.
-(excited) This is amazing news!
+```text
+[happy] What a beautiful day!
+[sad] I'm sorry to hear that.
+[excited] This is amazing news!
 ```
 
-The TTS models will automatically recognize these markers and adjust the voice accordingly.
