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.
Boyash
The Boyash are a branch/caste of the Roma who were forced to settle in the 14th century in the Apuseni Mountains, located in Transylvania, and work as slaves in mining (a regionalism for "mine" in Romanian: "baie," from Middle Age Slavonic). Due to their close proximity with the Romanian-speaking people, they lost the use of the Romani language, and started using the Romanian language. Some groups relearned Romani when they came in contact with other Romani-speaking Roma, after they later emigrated from Romania (for example, in Ecuador).
