+## Dataset Summary
 The origin dataset from: [PhoST](https://github.com/VinAIResearch/PhoST)
 
-In this STVi dataset, we split the origin audio into 1-15s corresponding to each sentence and spelling correction, normalization word
+A speech-to-text translation dataset with source audio in English and target sentences in Vietnamese.
+
+In this STVi dataset, we split the origin audio into 1-15s corresponding to each sentence and spelling correction, normalization word, audio segmentation
+
+## Data Structure
+
+```
+{'path': 'stvi/train/waves/315814.wav', 'audio': {'path': 'stvi/train/waves/315814.wav', 'array': array([-0.0050354 , -0.00296021, -0.00549316, ..., -0.0085144 ,
+       -0.00686646, -0.00018311]), 'sampling_rate': 16000}, 'sentence': 'tôi cảm thấy bẽ mặt và xấu hổ đến mức tôi chạy ngay về nhà với mẹ và trách phạt bà vì để tôi mặc cái áo gớm guốc'}

+
+### Data Fields
+- path: The path to the audio file
+- audio: A dictionary containing the path to the downloaded audio file, the decoded audio array, and the sampling rate.
+- sentence: The transcript sentence 
+
+### Data Splits
+
+The speech material has been subdivided into portions for train and test.
+
+Speech was recorded in a quiet environment with high quality microphone, speakers were asked to read one sentence at a time.
