A first touch input can indicate a selection of a character from a first virtual keyboard configured for an Indic script. A modified first virtual keyboard can be displayed in response to the first touch input when the selected character is a consonant, the modified first virtual keyboard including diacritic forms of vowels from the first virtual keyboard. A second virtual keyboard can be displayed in response to the first touch input when the selected character is a vowel and a duration of the first touch input is greater than or equal to a predetermined duration, the second virtual keyboard including at least one of (i) diacritic forms of the selected character and (ii) vowels having similar sounds as the selected character. A second touch input can indicate a selection of (i) a vowel from the modified first virtual keyboard or (ii) a vowel from the second virtual keyboard.
