On the other hand, transliteration software works on phonetics. A transliteration doesn't tell you the meaning of the words but it helps you pronounce them. What you type in Roman script is converted in Telugu script. For E.g. typing "Nenu Telugu bhaṣani premistunnanu" will be converted into "నేన తెలగ భాషని ప్రేమిస్తన్నాన".
