The purpose of this work is to develop a robust tool for normalization of Russian dialect texts using Character-level Statistical Machine Translation (CSMT). The work provides overview of normalization methods and state-of-the art text normalization techniques. The work describes experiments that were conducted in order to figure out how much data is needed for the model training, what type and size of additional text set for the language model is needed. As an outcome of this work, CSMT model was trained. The results show that the model outperformed the baseline at a statistically significant level, providing the accuracy of 84%.
