Technology has improved temporarily from time to time. There are a lot of technologies that had been developed to enhance language learning, and one of them is text-to-speech technology. Text-to-speech technology is a form of system that can convert phoneme to audio. It has provided an impact in language learning since it was developed. This article presents how the application of text-to-speech technology is used in language learning, including the negative and positive side of text-to-speech technology in language learning. It reports on the results of a systematic review of articles that specifically examine the use of text-to-speech technology in language learning. The articles were published between 2012 and 2022 and collected from several databases, including Google Scholar, Elsevier, SAGE, Springer, ERIC, IEEE, and Taylor & Francis. The articles were then reviewed and selected using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) approach. The analysis results of 20 selected articles revealed that the use of text-to-speech assisted the process of knowledge transfer. Text-to-speech technology has also played a practical role in language learning, especially in improving students' language skills. The review also revealed that text-to-speech technology lacks in intonation, eye-contact, and real-time class interaction. But overall, despite that it has a slight negative impact, text-to-speech technology can be a breakthrough to support language learning.
