Romanisation of Telugu

There are several systems for romanisation of the Telugu script.

Other diacritics

 * Virama (్) mutes the vowel of a consonant, so that only the consonant is pronounced. Example: క + ్ → క్  or  +  →.
 * Anusvara (ం) nasalize the vowels or syllables to which they are attached. Example: క + ం → కం or  +  →
 * Candrabindu (ఁ) also nasalize the vowels or syllables to which they are attached. Example: క + ఁ → కఁ or  +  →.
 * Visarga (ః) adds a voiceless breath after the vowel or syllable it is attached to. Example: క + ః → కః or +  →

UN romanisation for geographical names
The United Nations romanisation systems for geographical names (approved 1972, I1/11; amended in 1977 IH/12) was based on a report prepared by D. N. Sharma.

The UN romanisation uses macrons for long vowels ā ī ū, a dot under ṛ for vocalic r, and caron on ĕ and ŏ.
 * ka kā ki kī ku kū kṛ kĕ ke kai kŏ ko kau

ISO
There are differences between the UN system and the ISO transliteration standard ISO 15919: 2001

ITRANS
ITRANS also has transliteration for Telugu.

RTS
Used in Vemuri Rao's English-Telugu Dictionary (2002) Rice University's Reverse Transliteration System (RTS) (created by Ramarao Kanneganti and Ananda Kishore) can be used for the transliteration of Telugu into Roman script as an alternative to phonetic alphabet. The RTS is defined below. (1) Represent short vowels by the lower case ..." The result is a phonetic representation mostly suitable for dictionaries and computer input methods. Examples:
 * RTS represents short vowels by the lower case English character and long vowels by the corresponding upper case character: అ = a, ఆ = A; etc.
 * Unaspirated consonant-vowel pairs are represented by a lower case letter followed by a suitable vowel.
