+# Corpus
+
+This dataset is built from Magicdata [ASR-CCHSHDIACSC: A CHINESE CHANGSHA DIALECT CONVERSATIONAL SPEECH CORPUS](https://magichub.com/datasets/changsha-dialect-conversational-speech-corpus/)
+
+This corpus is licensed under a [Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License](http://creativecommons.org/licenses/by-nc-nd/4.0/). Please refer to the license for further information.

+# Usage
+
+To load this dataset, use
+
+```python
+from datasets import load_dataset
+dialect_corpus = load_dataset("TingChen-ppmc/Changsha_Dialect_Conversational_Speech_Corpus")
+```
+
+This dataset only has train split. To split out a test split, use
+
+```python
+from datasets import load_dataset
+train_split = load_dataset("TingChen-ppmc/Changsha_Dialect_Conversational_Speech_Corpus", split="train")
+# where test=0.5 denotes 0.5 of the dataset will be split to test split
+corpus = train_split.train_test_split(test=0.5)
+```
+
+A sample data would be
+
+```python
+{'audio': 
+	{'path': 'A0001_S001_0_G0001_0.WAV',
+  	 'array': array([-0.00030518, -0.00039673,

+  	 'sampling_rate': 16000},
+ 'gender': '女',
