Baltic Romani
There are three simple stop positions in the Romani language. These come from the Indo-Aryan and are maintained in every dialect of this language. The positions are as follows; labial /p/, dental /t/, and velar /k/. Along with these stop positions, there are also palatal positions which are unique to the Romani language. Specific voicing alterations have changed grammatical endings and different dialects have different ways of interpreting vowels. Some have morphed into newer versions of the Romani language and others have implemented other elements like screams.
Bohemian Romani
In the early 20th century, Bohemian Romani was, at least in some groups of Bohemian Roma, gradually becoming a non-native ethnic language, acquired in late childhood and used mostly for secretive purposes (cf. Lesný 1916: 214–216, Lípa 1960: 50). Clearly, a development had started toward a Para-Romani variety, that is, a specialized non-native variety spoken by Roma, which has the grammar of a majority language (Czech in this case) as well as an access to Romani-derived lexicon (Elšík 2003: 44).
