 ## Getting Started
@@ -24,7 +30,7 @@ To use fine-grained control, you can use either our SDK, API, or Playground.
 
 SDK/API: Phoneme tags are preserved by text normalization, so you can keep the default normalization behavior for pronunciation control. Set `"normalize": false` only when you want to prevent normalization from rewriting the surrounding text, such as numbers, dates, or URLs.
 
-Playground: You can use V1.6 Control Model, without setting any other options.
+Playground: Use `s2-pro` or `s1`. Both models support phoneme control with `<|phoneme_start|>` and `<|phoneme_end|>` tags.

   Disabling normalization may reduce the stability of reading numbers, dates,

-## Paralanguage
-
-Paralanguage controls allow you to add natural speech elements and pauses to make the generated speech sound more human-like. There are two main types of controls:
-
-### Pause Words
-
-You can use common pause words like "um", "uh", "嗯", "啊" to control the rhythm of the speech.
-
-### Special Effects
+## Emotion and Paralanguage Control
 
-The following special effects can be added using parentheses:
+For pauses, laughter, breathing, emotion, tone, and other paralinguistic cues, use the [Emotion Control](/developer-guide/core-features/emotions) guide.
 
-| Effect           | Description        | First Available | Stage        |
-| ---------------- | ------------------ | --------------- | ------------ |
-| `(break)`        | Short pause        | V1.6            | Experimental |
-| `(long-break)`   | Extended pause     | V1.6            | Experimental |
-| `(breath)`       | Breathing sound    | V1.6            | Experimental |
-| `(laugh)`        | Laughter sound     | V1.6            | Experimental |
-| `(cough)`        | Coughing sound     | V1.6            | Experimental |
-| `(lip-smacking)` | Lip smacking sound | V1.6            | Experimental |
-| `(sigh)`         | Sighing sound      | V1.6            | Experimental |

-<Warning>
-  The effects `(laugh)`, `(cough)`, `(lip-smacking)`, and `(sigh)` are
-  developing. You may need to repeat them multiple times for better results.

-Example:

-```text
-I am, um, an (break) engineer.

+`s2-pro` uses `[bracket]` cues such as `[laughing]` and `[break]`. `s1` uses `(parentheses)` syntax. See the Emotion Control guide for the current supported marker lists and examples.
