Abstract—Text to Speech (TTS) synthesis is a process of translating natural language text into speech. Pieces of recorded speech generate synthesized speech and a database is maintained for storing this synthesized speech. A speech synthesizer’s output is determined through its resemblance to the person utter and its capacity to be implied. In recent years between the two main subsections: machine learning and deep learning of Artificial Intelligence (AI), deep learning has achieved huge success in the domain of text to speech synthesis. In this literature, a taxonomy is introduced which represents some of the deep learning-based architectures and models popularly used in speech synthesis. Different datasets that are used in TTS have also been discussed. Further, for evaluating the quality of the synthesized speech some of the widely used evaluation matrices are described. Finally, the paper concludes with the challenges and future directions of the text-to-speech synthesis system.
Index Terms—Text to Speech (TTS), deep learning, acoustic features, parametric synthesis, concatenative synthesis, text analysis
