 ### Dataset Description
 
-In total 4 different accents. 2 speakers per accent (female and male):
+The audios from this dataset have been created with professional studio recordings by professional voice actors in Lafresca Creative Studio.
+We processed the raw audios with the following recipe:

+- **Trimming:** Long silences from the start and the end of clips have been removed.
+  - [py-webrtcvad](https://pypi.org/project/webrtcvad/) -> Python interface to the Voice Activity Detector (VAD) developed by Google for the WebRTC.

+- **Resampling:** From 48000 Hz to 22050 Hz, which is the most common sampling rate for training TTS models
