The presented TTS (text-to-speech) application is an auxiliary tool for language teaching. It utilizes computer-generated voices to simulate dialogs representing different grammatical problems or speech contexts. The software is capable of producing as many examples of dialogs as required to enhance the language learning experience and thus serve curriculum representation, grammar contextualization and pronunciation at the same time. It is designed to be used on a regular basis in the language classroom and students gladly write materials for listening comprehension tasks with it.
