Indian Text to Speech Systems: A Short Survey

Speech and spoken words have always played a key role in everyday life. Speech synthesis is a means of artificially synthesizing speech, whereas text-to-speech (TTS) is a technology that converts written text in a human language into an analogous spoken waveform [speech form].The written form is represented by the text, a sequence of characters, whereas the verbal form is represented by the speech. TTS synthesizers are computer-based systems that read text out loud. The TTS system is divided into two phases: text processing and speech creation. Despite the availability of several TTS systems in various languages, Indian languages continue to lag behind in terms of producing high-quality speech. Acceptability and intelligibility are used to rate the quality of speech. The main objective of this paper is to perform a study on available text-to-speech technologies in Indian languages.
