This paper describes a project for creating an online system for studying the main formant movements of Hungarian vowels in spoken words, as a function of their sound environment. The speech material and the formant data corresponding to the vowels combined present research data for many other purposes as well. For efficient presentation of the data and to allow multilevel comparisons among formant features an online solution was developed. The inventory data can be regarded as a reference, because of the strict conformity between the defined formant data and the formants of the spoken words. A two-step manual verification phase after the completion of automatic formant tracking was performed. The on-line query ensures quick and wide spread studying of formant maps in vowels. The database is available at: "http://hungarianspeech.tmit.bme.hu/formant".
