-import edge_tts
+"""
+This module provides a serverless API for text-to-speech conversion using Edge TTS.
+
+It includes functionality to generate audio and subtitles from input text,
+utilizing the edge_tts library. The main function, `run`, is designed to be
+used in a serverless environment, returning an asynchronous generator that
+yields audio data and subtitles.
+
+Dependencies:
+    - edge_tts: For text-to-speech conversion
+    - typing: For type hinting
+
+Usage:
+    The main entry point is the `run` function, which takes text input
+    and an optional voice parameter to generate audio and subtitles.
