The new research idea focuses on automatic assistance to be developed for the visually impaired and illiterates. This work aims at hardcopy text extracted and recognized from images in bilingual languages (Tamil and English). The recognized text is then converted into machine-readable text using optical character recognition (OCR) technique and then compared with the stored character set. The proposed approach is capable of recognizing text in a variety of challenging conditions where traditional character recognition systems fail, notably in the presence of substantial blur, low resolution, low contrast, high image noise, and other distortions. The text will then be processed by Microsoft Speech Application Program Interface (SAPI) speech synthesizer and translated to voice as output in both English and Tamil languages. The framework is on implementing the image capturing technique in the embedded system based on Raspberry Pi board and converting it into voice using Win32 SAPI. This model can recognize and convert a maximum of 20 Tamil characters.
