Abstract :In Human-Computer Interaction, lip reading is essential and still an open research problem. In the last decades, there have been many studies in the field of Automatic Lip-Reading (ALR) in different languages, which is important for societies where the essential applications developed. Similarly to other machine learning and artificial intelligence applications, Deep Learning (DL) based classification algorithms have been applied for ALR in order to improve the performance of ALR. In the field of ALR, few studies have been done on the Turkish language. In this study, we undertook a multifaceted approach to address the challenges inherent to Turkish lip reading research. To begin, we established a foundation by creating an original dataset meticulously curated for the purpose of this investigation. Recognizing the significance of data quality and diversity, we implemented three robust image data augmentation techniques: sigmoidal transform, horizontal flip, and inverse transform. These augmentation methods not only elevated the quality of our dataset but also introduced a rich spectrum of variations, thereby bolstering the dataset\'s utility. Building upon this augmented dataset, we delved into the application of cutting-edge DL models. Our choice of models encompassed Convolutional Neural Networks (CNN), known for their prowess in extracting intricate visual features, Long-Short Term Memory (LSTM), adept at capturing sequential dependencies, and Bidirectional Gated Recurrent Unit (BGRU), renowned for their effectiveness in handling complex temporal data. These advanced models were selected to leverage the potential of the visual Turkish lip reading dataset, ensuring that our research stands at the forefront of this rapidly evolving field. The dataset utilized in this study was gathered with the primary objective of augmenting the extant corpus of Turkish language datasets, thereby substantively enriching the landscape of Turkish language research while concurrently serving as a benchmark reference. The performance of the applied method has been compared regarding precision, recall, and F1 metrics. According to experiment results, BGRU and LSTM models gave the same results up to the fifth decimal, and BGRU had the fastest training time.
