An electronic apparatus and method for visual speech recognition based on connectionist temporal classification (CTC) loss is disclosed. The electronic apparatus receives a video that includes human speakers and generates a prediction corresponding to lip movements of the human speakers. The prediction is generated based on application of a Deep Neural Network (DNN) on the video and the DNN is trained using a CTC loss function. The electronic apparatus detects, based on the prediction, word boundaries in a sequence of characters that correspond to the lip movements and divides the video into a sequence of video clips based on the detection. Each video clip corresponds to a word spoken by the human speakers. The electronic apparatus generates a sequence of word predictions by processing the sequence of video clips and generates a sentence, or a phrase based on the generated sequence of word predictions.
