Conclusions 90 - Significance of Tess2Speech

D. Significance of Tess2Speech

VII. Conclusions 90

Tess2Speech is an Intelligent Character Recognition Android application which can recognize both computer-typed and non-cursive handwritten texts and convert it to either text or speech. With the help of Tess2Speech Trainer, which is a desktop application, Tess2Speech is re-trainable and can be personalized by the users with minimal effort.

Tess2Speech is developed to provide the speech impaired a way to commu- nicate, and also to provide researchers a free, open-source, non-proprietary ICR which is trainable.

This application also proves that Tesseract is indeed trainable for handwritten texts. Although, it is only limited to non-cursive handwritten texts since Tesseract relies on segmentation of characters. Because of this, it can be said that it is almost impossible to recognize cursive texts using Tesseract.

The development of this application also helped to determine the limitations and capabilities of Tesseract, and what training methods and configurations are effective for achieving high accuracy with Tesseract.

This application is currently at its Beta stage. Once it gains popularity, differ-

ent users and researchers may collaborate to improve the trained data for hand-

writing until such time that they create a generalized trained data for most, if not

all, handwritten texts.

VIII. Recommendations

It is suggested that in order to further improve the accuracy of Tess2Speech’

handwriting recognition, a higher number of sample handwritings (n-users) should be used. A higher number of characters and words are also suggested when creating training datasets.

Improving the canvas functionality of Tess2Speech that can rival Galaxy Note’s can greatly improve the accuracy of Tess2Speech when recognizing handwritten texts on the phone’s screen.

One of the main reason why the accuracy of Tesseract drops is because of image noises. Using open-source libraries for image pre-processing or developing an algorithm that can greatly reduce image noises can drastically improve Tesser- act’s accuracy. Such algorithms are adaptive thresholding and applying different binarization techniques.

Another improvement would be finding a way to train Tesseract in a smart phone so that Tess2Speech Trainer will not be needed. It can open a possibilty for Tesseract to learn handwritings dynamically without user intervention.

Adding functionality like language translator can also add usability to Tess2Speech.

Lastly, if there is an open-source OCR Engine which is better than Tesseract, you

can completely replace the OCR engine of this application.
