Speech synthesis large-scale integration (LSI) refers to the use of large-scale integration technologies to develop and deploy speech synthesis systems. It involves integrating electronic components and circuits into a single chip or a compact system that can generate human-like speech from text input. The goal of LSI in speech synthesis is to create more powerful, efficient, and compact systems that can deliver high-quality speech output in various electronic devices.

The main types of speech synthesis large-scale integration (LSI) include acoustic models, articulatory models, and natural speech models. Acoustic models in speech synthesis represent how sounds are produced by analyzing audio data and mapping it to text using algorithms to replicate the acoustic features of human speech. The technology types include text-to-speech (TTS), concatenative synthesis, formal synthesis, and neural networks for device types such as smartphones, tablets, smart speakers, smart televisions (TV), automotive infotainment systems, and medical devices. The applications include consumer electronics, automotive, healthcare, industrial, public safety, and education.
