They are Ayizo, Kotafon, and Gbesi.
The Ayizo languages are spoken in Benin across and near the Mono River, in the Departments of Atlantique, Kouffo, Mono, Oueme, and parts of the Zou Department.
The Ayizo alphabet is based on the Latin alphabet, with the addition of the letters Ɖ/ɖ, Ɛ/ɛ, and Ɔ/ɔ, and the digraphs gb, hw, kp, ny, and xw.
The tone marking is phonemic, and the actual pronunciation may be different according to the syllable's environment.
