Conclusions
This thesis provides the complete design and implementation of Embedded Shruti. It started with an introduction to technologies that were used in this software product. After that details of different models were provided. The last chapter provides a comparison of the performance of different models and the reason for choosing Model 3 as the final implementation.
Embedded Shruti has several advantages over the desktop version. To run the desktop version one need a desktop computer system that is costly compared to a Personal Digital Assistant like Pocket-PC. Pocket-PC is a mobile device and therefore the software can be used on the move by the user. A person with speech disorders only have to carry a PDA with Embedded Shruti installed on it. The person can communicate with others using the software and since it is installed on a PDA rather than a desktop computer he can take the software with him at any place.
I personally feel that Embedded Shruti realizes the dream of providing Shruti software to every person who needs it. For a person with speech disorders this software will be an integral part of life. Carry a Personal Digital Assistant having Embedded Shruti and you have the power to communicate with people despite your serious speech disorders.

Future Work
Embedded Shruti is to be tested completely on a number of variable length test inputs. Hindianalyser module is tested completely but Hindiengine module is not rigorously tested. The software is giving perfect results for the input strings on which it is tested till now but still more testing is required.
The final version which is to be shipped to customers will save the voice database, intonation database and epoch database on a Flash rather than on the secondary storage of the Pocket-PC device. Flash comparatively takes less time than disc and so it will surely increase the performance. A Flash version of the code is to be written. In the Flash version of the code, the path of the database has to be changed. Presently since the database is on the root directory of Pocket-PC, the path is simply the name of the database like “voice.db”. For example when the database is opened, the path of the database is “voice.db”. But when a Flash will be connected to the device the path will change to “\Storage Card\voice.db”. In the Flash version of the code this change will be incorporated.
The software is tested on Pocket-PC emulator till now. Once the testing and debugging is done it will be ported on Pocket-PC hardware. The databases, the dynamic link libraries (hindianalyser, hindiengine and gdbmce) and the application Frontend.exe will be transferred to the device using eMbedded Visual C++. The environment is changed to Pocket-PC (default device) from Pocket-PC (Emulation) and the device will be connected to the development workstation using some COM port. After that the files can be transferred to Pocket-PC.
