This paper describes the development of free/open-source finite-state morphological transducers for three Turkic languages-Kazakh, Tatar, and Kumyk-representing one language from each of the three commonly distinguished sub-branches of the Kypchak branch of Turkic. The finite-state toolkit used for the work is the Helsinki Finite-State Toolkit (HFST). This paper describes how the development of a transducer for each subsequent closely-related language took less development time. An evaluation is presented which shows that the transducers all have a reasonable coverage-around 90%-on freely available corpora of the languages, and high precision over a manually verified test set.
