Kaba proper is a Bongo–Bagirmi language of Chad and the Central African Republic. It is one of several local languages that go by the names Kaba and Sara. There are three ISO codes, which Ethnologue acknowledges may be the same thing.

Phonology

• /k/ can often be heard as a uvular plosive [q].
• /k/ can also often be pronounced as a fricative /x/ by some speakers.
• /ɗ/ is often interchangeable with [r], but is pronounced [ɗ] in careful speech, except word-finally, where it is pronounced [r].
• /tʃ/ is only found in one word.

• Vowel length is often not regarded to be phonemic, but it is a contrastive feature in the verbal morphology.

Kaba has three tones: high, low, and mid.^[2]
