+## Dataset Overview
+- The dataset is a curated collection of `.npy` files containing MFCC features extracted from raw audio recordings. 
+- It has been specifically designed for training and evaluating machine learning models in the context of real-world emergency sound detection and classification tasks. 
+- The dataset captures diverse audio scenarios, making it a robust resource for developing safety-focused AI systems, such as the `SilverAssistant` project.
+
+## Dataset Description
+- The dataset used for this audio model consists of `.npy` files containing MFCC features extracted from raw audio recordings. These recordings include various real-world scenarios, such as:
+    - Criminal activities
+    - Violence
+    - Falls
+    - Cries for help
+    - Normal indoor sounds
+
+- Feature Extraction Process
+    1.	Audio Collection:
+        - Audio samples were sourced from datasets, such as AI Hub, to ensure coverage of diverse scenarios. 
+        - These include emergency and non-emergency sounds to train the model for accurate classification.
+    2.	MFCC Extraction:
+        - The raw audio signals were processed to extract Mel-Frequency Cepstral Coefficients (MFCC).
+        - The MFCC features effectively capture the frequency characteristics of the audio, making them suitable for sound classification tasks.
+        ![MFCC Output](./pics/mfcc-output.png)
+    3.	Output Format:
+        - The extracted MFCC features are saved as `13 x n` numpy arrays, where:
+        - 13: Represents the number of MFCC coefficients (features).
+        - n: Corresponds to the number of frames in the audio segment.
+    4.	Saved Dataset:
+        - The processed `13 x n` MFCC arrays are stored as `.npy` files, which serve as the direct input to the model.
