Using earlier information to fill in the holes that can happen in comprehension since it is difficult to peruse each word said.Ĭuriously, it is simpler to peruse longer words and entire sentences than shorter words. Reading and assessing the data gave by outward appearances, non-verbal communication and motions related to the words being said Learning to utilize the signals gave by the developments of the speaker's mouth, teeth and tongue

Frequently called "a third ear," lip perusing goes past just perusing the lips of a speaker to decode singular words.įiguring out how to lip read includes creating and rehearsing certain abilities that can make the procedure a lot simpler and progressively successful. Lip perusing permits you to "tune in" to a speaker by viewing the speaker's face to make sense of their discourse designs, developments, signals and demeanours. After the visualisation is completed, the captured movements are then converted into the form the person can understand easily. This application uses LRW dataset to visualise every movement of the lips.

This file contains the weights pre-trained using ImageNet dataset. In folder CNN/pretrained-VGG16, the file vgg16_weights.npz is also left out due to its large size.In folder Video Processing, the file shape_predictor_68_face_landmarks.dat, which was used to detect lips region, is left out due to its large size.Another dataset that I plan to use in this project is the BBC-Oxford 'Multi-View Lip Reading Sentences' (MV-LRS) Dataset, which can be found HERE.In the folder GRID corpus/vectors, only 100 vector representations of 100 videos are shown to demonstrate the method. The GRID corpus contains 33,000 facial recordings.Williams, 1992 Zaremba & Sutskever, 2015Īsynchronous Advantage Actor Critic (A3C) The three RL methods implemented on this project are: Method A reward function: BLEU - evaluating the similarity between the generated text and the ground truth.An action refers to predicting the next word in the sequence at each time step.A policy: the parameters of the generative model.An environment contains the words and the context vector it sees as input at every time step.An agent: the generative model (RNN with LSTMs).The components of RL in Lip Reading setting: Long Short-Term Memory network: a recurrent neural network with long short-term memory cells acts as an agent that used REINFORCE to learn its parameters. Three dominant components of the model are:Ĭonvolutional Neural Network: VGG16 model pre-trained on ImageNet dataset was used to transform images of the lips region to its vector representation. This project aims to tackle lip reading by modeling an agent that is capable of learning the features by interacting with the environment using reinforcement learning methodology.

This task, however, is challenging, due to factors such as the variances in the inputs (facial features, skin colors, speaking speeds, etc.) and the one-to-many relationships between viseme and phoneme. It can also be an extremely helpful tool for people who are hearing-impaired to communicate through video calls. Lip reading, also known as audio-visual recognition, has been considered as a solution for speech recognition tasks, especially when the audio is corrupted or when the conversation happened in noisy environments.
