Overview
The Language Technology Laboratory focuseson the following topics: Speech recognition Speaker, spoken language and accentidentification Speech corpora Phonetics (Estonian language prosody andvocal system, L2 speech) Various sub-topics of natural languageprocessingOne of the important activities is the creationof speech technology applications targeted atsociety as a whole. This includes applications ofend-user speech recognition as well as the keyintegration components that are easy to integrate. Although the focus is on speech recognition in Estonian, most of the software createdin the laboratory is not specific to Estonian. Thelaboratory is a solid open source free software supporter.
