-    Generates TTS audio using the ChatterboxTTS model.
+    Generate high-quality speech audio from text using ChatterboxTTS model with reference audio styling.
+    
+    This tool synthesizes natural-sounding speech from input text, using a reference audio file 
+    to capture the speaker's voice characteristics and speaking style. The generated audio 
+    maintains the prosody, tone, and vocal qualities of the reference speaker.
 
     Args:
-        text_input: The text to synthesize (max 300 characters).
-        audio_prompt_path_input: Path to the reference audio file.
-        exaggeration_input: Exaggeration parameter for the model.
-        temperature_input: Temperature parameter for the model.
-        seed_num_input: Random seed (0 for random).
-        cfgw_input: CFG/Pace weight.
+        text_input (str): The text to synthesize into speech (maximum 300 characters)
+        audio_prompt_path_input (str): File path or URL to the reference audio file that defines the target voice style
+        exaggeration_input (float): Controls speech expressiveness (0.25-2.0, neutral=0.5, extreme values may be unstable)
+        temperature_input (float): Controls randomness in generation (0.05-5.0, higher=more varied, default=0.8)
+        seed_num_input (int): Random seed for reproducible results (0 for random generation)
+        cfgw_input (float): CFG/Pace weight controlling generation guidance (0.2-1.0, default=0.5)
 
     Returns:
-        A tuple containing the sample rate (int) and the audio waveform (numpy.ndarray).
+        tuple[int, np.ndarray]: A tuple containing the sample rate (int) and the generated audio waveform (numpy.ndarray)
