Toto is listed as a critically endangered language by UNESCO, with perhaps 1,000 speakers.[3] However, most families in the community speak Toto at home. Most children learn Toto at home, although they use Bengali in school.
Anthropological Survey of India (AnSI) set out to conduct a study on language of the Toto tribe, whose population has dwindled to 1,536, they did not realize that the language is more endangered than the tribe itself. Researchers as well the members of the Toto community admit that the language is under threat and the influence of other languages, particularly Nepali and Bengali, is increasing day by day.[4]

Consonants
With regards to consonants, Toto has an inventory of seven sonorants (nasals and liquids) and twelve obstruents (stops and fricative), eight of which are contrastive in voicing. It also distinguishes the voiceless obstruents /t/ and /p/ with their aspirated equivalents /tʰ/ and /pʰ/, respectively.[1]
An alphabetic script developed for the language by community elder and author, Dhaniram Toto, was published in 2015, and has seen limited but increasing use in literature, education, and computing; most significantly, the Toto alphabet was added to the Unicode Standard in September, 2021. Prior to the publication of this script, Dhaniram Toto and other members of the community (whose literacy rate as per sample survey carried out in 2003 was just 33.64 per cent) penned books and poems in the Bengali script.[4]
