Whistled languages use whistling to emulate speech and facilitate communication. A whistled language is a system of whistled communication which allows fluent whistlers to transmit and comprehend a potentially unlimited number of messages over long distances. Whistled languages are different in this respect from the restricted codes sometimes used by herders or animal trainers to transmit simple messages or instructions. Generally, whistled languages emulate the tones or vowel formants of a natural spoken language, as well as aspects of its intonation and prosody, so that trained listeners who speak that language can understand the encoded message.
The Chinantec or Chinantecan languages constitute a branch of the Oto-Manguean family. Though traditionally considered a single language, Ethnologue lists 14 partially mutually unintelligible varieties of Chinantec.

Kirundi, also known as Rundi, is a Bantu language spoken by some 9 million people in Burundi and adjacent parts of Rwanda, Tanzania, the Democratic Republic of the Congo, Uganda, as well as in Kenya.

The Oto-Manguean or Otomanguean languages are a large family comprising several subfamilies of indigenous languages of the Americas. All of the Oto-Manguean languages that are now spoken are indigenous to Mexico, but the Manguean branch of the family, which is now extinct, was spoken as far south as Nicaragua and Costa Rica. Oto-Manguean is widely viewed as a proven language family. However, this status has been recently challenged.

It is spoken by around 97,000 people in the country, and another few thousand speakers in Cameroon. The language's presence on the southeastern edge of the Mbum family is thought to reflect early 19th-century migrations from the Adamawa Plateau, fleeing Fulani raids.
