Bengali Vocal Spectrum (BVS): A Bengali Voice Dataset for Psychological Stability Analysis

The dataset is divided into two groups: 43 recordings (2.63 hours) from psychologically unstable patients and 42 recordings (2.02 hours) from psychologically stable individuals. These recordings were collected at Pabna Mental Hospital, Pabna, and National Institute of Mental Health & Hospital, Dhaka.

The dataset was compiled with a firm commitment to ethical standards, including obtaining all necessary permissions and ensuring the confidentiality and anonymity of all participants. The data was meticulously preprocessed using Audacity software to normalize the volume, remove background noise, and ensure clarity, with each file saved in .wav format at a 48000 Hz sample rate. Spectrogram images are in a separate folder and segmented into 2-second clips from the audio data for signal processing techniques, enhancing the utility of the dataset for machine learning applications.
