Psychiatric Disorders With Speech

Mail to [email protected] to collabarate

Mental health is important at every stage of life, from childhood and adolescence through adulthood, even more in the digital world created due to the ongoing pandemic and lockdown. Although we have huge medical research on these disorders, there is no lab test to diagnose any of the disorders. Moreover, early detection of degenerative disease can prevent irreversible changes if detected at a later stage during EEG, MRI, etc. In today's world of voice automation, virtual classes, and meetings, speech data is the easiest sample that can be collected from anyone, using existing devices like phones, laptops.

In this project, we wish to identify psychiatric disorders through patient's speech

Task 1 : Import the data from Mobile Device Voice Recordings at King's College London (https://zenodo.org/record/2867216#.X5-_tNtS-gQ). Create a PyTorch dataloader for the dataset and layout procedure for adding more datasets in future.

Task 2 : Create scripts to visiualize the data using matplotlib, or any other python package. Implement any Machine Learning algorithm on the loaded dataset to define training and evaluation flow.

Task 3 : Reproduce the results from https://www.ijraset.com/fileserve.php?FID=31054

Task 4 : Implement any Machine Learning algorithm with or without(end-to-end) feature engineering . To start off, use https://github.com/espnet/espnet.

Task 5 : Create pytorch data loader for all the speech datasets listed below. (about 20)

Task 6 : Convert the speech dataset to words for NLP analysis.

We wish to explore state of the art RNN architectures (GRU, LSTM, seq-to-seq, etc.), transfer learning and meta-learning (learning to learn) approaches for this task. These algorithms would be deployed in real time, low power mobile devices for identifying mental disorders from voice-calls, meetings, etc.

Aspects to explore

1. Acoustic features independent of context. Pitch, pauses, pronounciation etc.
2. Language features : The patterns present in speech-text converted corpus.
