The CALLFRIEND project supports the development of language identification technology.
The corpus consists of 60 unscripted telephone conversations, lasting between 5-30 minutes. The corpus also includes documentation describing speaker information (sex, age, education, callee telephone number) and call information (channel quality, number of speakers).
For each conversation, both the caller and callee are native speakers of the Egyptian dialect of Arabic. All calls are domestic and were placed inside the continental United States and Canada.
