【 摘 要 】

The problem of automatic speech generation from a text file is considered. An analytical review of the software has been completed. They are designed to recognize texts and convert them to an audio stream. The advantages and disadvantages of software products are estimated. Based on this, a conclusion was drawn about the relevance of developing a software for automatic generation of an audio stream from a text in Russian. Models based on artificial neural networks, which are used for speech synthesis, are analyzed. After that, a mathematical model of the created software is built. It consists of three components: a convolutional encoder, a convolutional decoder, and a transformer. The architecture of the software is designed. It includes a graphical interface, an application server, and a speech synthesis system. A number of algorithms have been developed: preprocessing text before loading it into a software, converting audio files of a training sample and training a network, generating speech based on arbitrary text files. A software has been created, which is a single-page application and has a web interface for interacting with the user. To assess the quality of the software, a metric was used that represents the average score of different opinions. As a result of the aggregation of different opinions, the metric received a sufficiently high value, on the basis of which it can be assumed that all the tasks have been solved.
