This 1949 monograph by Valentina Sokolova stands as a pioneering experimental study of the phonetic system of the Tajik language. Published as part of the Iranian Series under the editorship of the eminent scholar Vasily Abaev, the text provides a deep dive into the internal logic of Tajik articulation and acoustics, including the arrangement of vowel and consonant systems through the use of kymographic and oscillographic data. As a vital primary source, this volume documents the transition of Tajik linguistics toward modern empirical methods during the late 1940s.  The work is significantly enhanced by technical illustrations and maps outlining dialectal phonetic variations, reflecting the high academic rigor of the N. Marr Institute of Language and Thought. Despite its "satisfactory" condition and the presence of deaccessioned library stamps, this large-format academic edition remains a substantial bibliographical rarity. It is an essential resource for Iranian philologists, specialists in Semitic-Iranian linguistic contact, and historians of Soviet linguistics who study the foundational research that shaped modern Tajik grammar and orthography.
