It is spoken natively by the Saho people who traditionally inhabit territory in Eritrea bounded by the bay of Erafayle in the east, the Laasi Ghedé valleys in the south, and the Eritrean highlands to the west (Akele-Guzai, Shimejana).
This speech area is bordered by other Afro-Asiatic-speaking communities, with Tigre speakers on the west and Afar speakers on the east. In Ethiopia, Saho is primarily spoken in the Tigray Region. It has about 200,000 speakers in total and four main dialects: Toroa, Assaorta, Minifero and Irob.
Saho is so closely related to the Cushitic Afar language, spoken as a mother tongue by the Afar people, that some linguists regard the two tongues as dialects of a single "Saho–Afar language".

The Saho also use the Latin letters to document their history and render information. Also recently the language is being used on the cyberspace as a tool of communication.
