This paper presents data from a small corpus of unscripted speech gathered from one male and one female adult native speaker of Hindi. An acoustic analysis of the data demonstrated changes such as lenition and assimilation. The cases of assimilation included stop plus stop sequences yielding geminates. The results of a perceptual test showed that such ‘pseudogeminates’ are generally perceived as true geminates. Parallels between these phenomena and historical sound changes in Indo-Aryan are also discussed.
