Comparative study • We conducted a comparative study of these three screen readers, based on

37 different parameters.

• The parameters were derived from the 12 principals which are used to design an ideal screen reader[9].

• The conclusions of our comparative study are as follows:

– Advantages of ORCA in Indian scenario over other two SR

• Free and hence can serve the masses.

• Available in many Indian languages, which are not supported by the

other two screen readers

• Can be customized to speak in any Indian language


Road Ahead

• Sound quality of orca needs to be improved by developing a better

quality speech engine

• User friendly Training and User manuals have to be prepared

• Quality of end-user support has to improve and become more user

centric

• State IT policies need to be amended to promote open source amongst

its people and organizations

• Establish NGOs to promote and support ORCA, these NGOs will form a

bridge between the orca development team and the users


Conclusions and Summery

• Advantages of ORCA in Indian scenario over other

two SR

• Free and hence can serve the masses.

• Available in many Indian languages, which are not

supported by the other two screen readers

• Can be customized to speak in any Indian language
