Caption flow - A Subtitle Generator

This project aims at improving the accessibility of people with hearing impairment by developing a lip reading model based on deep learning, implemented in Python and TensorFlow. The model is trained by extracting the mouth region from relevant data video files from the GRID dataset, performing normalization, and aligning the data which prepares the data for more efficient model learning. The model architecture includes 3D convolutions. LSTM networks are provided for the efficient processing of video sequences. A custom model was created to tackle the problem posed by unaligned sequences by employing a CTC loss function. Variation of the speech rate is easily countered by the model. The evaluation of the model is carried out by visual representation of the predictions and actual transcriptions to quantify the performance of the model in order to increase performance. The project analyzes potential applications of lip reading technology for improving communication accessibility. Visualization of predictions against actual transcriptions is employed to evaluate the model's accuracy and identify areas for improvement. The project also explores the potential for real-world applications of lip-reading technology, particularly in enhancing communication accessibility. Future plans include the development of a standalone application to bring this technology to practical use.
