+## Unreal Text to Speech
+
+### What it is
+A specialized block that converts written text into spoken audio using the Unreal Speech API service.
+
+### What it does
+This block takes text input and transforms it into natural-sounding speech, creating an audio file that can be accessed via a URL. It utilizes Unreal Speech's advanced text-to-speech technology to generate high-quality voice output.
+
+### How it works
+1. The block receives text input and voice preferences from the user
+2. It securely connects to the Unreal Speech API using provided credentials
+3. The text is processed and converted to speech using the specified voice
+4. The API generates an MP3 audio file and returns its URL
+5. The block provides the URL where the audio file can be accessed
+
+### Inputs
+- Text: The written content you want to convert into speech (required)
+- Voice ID: The specific voice you want to use for the speech generation (defaults to "Scarlett")
