Abstracts: Optical character recognition, usually abbreviated to OCR, is the mechanical or electronic conversion of scanned images of handwritten,typewritten or printed text into machine-encoded text.It is a common method of digitizing printed texts so that they can be electronically searched, stored more compactly, displayed on-line, and used in machine processes such as machine translation and text mining. OCR is a field of research in pattern recognition, artificial intelligence and computer vision.It is widely used as a form of data entry from some sort of original paper data source, whether documents, sales receipts, mail, or any number of printed records.A text-to-speech (TTS) system converts normal language text into speech; other systems render symbolic linguistic representations like phonetic transcriptions into speech.
