Indian English has developed a number of dialects, distinct from the General/Standard Indian English that educators have attempted to establish and institutionalise, and it is possible to distinguish a person's sociolinguistic background from the dialect that they employ. These dialects are influenced by the different languages that different sections of the country also speak, side by side with English. The dialects can differ markedly in their phonology, to the point that two speakers using two different dialects can find each other's accents mutually unintelligible.

Indian English is a "network of varieties", resulting from an extraordinarily complex linguistic situation in the country. (See Official languages of India.) This network comprises both regional and occupational dialects of English. The widely recognised dialects include Malayali English, Telugu English, Maharashtrian English, Punjabi English, Bengali English, Hindi English, alongside several more obscure dialects such as Butler English (a.k.a. Bearer English), Babu English, and Bazaar English and several code-mixed varieties of English.

The formation of these regional/socio-economic dialects is the same form of language contact that has given rise to Scottish English.
