degree in electrical and electronic engineering

well DSP!!! You can Make MODBUS using TI's DSP controller.. this is a quite new way.

I am not a electrical engineer but I have learned DSP subject and have very good interest in robotics. Here is few ideas for project :
#-> Home automation using speech (not voice) recogniation
#-> Voice encryptor & decryptor (can be used for secure voice communication)
#-> File transfer through sound using DSP module(very helpful when file transfer is not available)

This all are based on DSP, I dont suggest any projects in Robotics cause it demands high budget, good mechanical knowledge, patience & time. So it is not suitable according to me. But if you want to have some big project than you can opt for the Robotics. Feel free to ask about any of the above project.

Hi
i am EEE student. I need the ideas of following projects,

*Home automation using speech (not voice) recogniation
*Voice encryptor & decryptor (can be used for secure voice communication)

Here is the little description of the project idea,
*Home automation using speech (not voice) recogniation>
In this automation system, we have to build a module, that recognize the speech, and then follows the instruction. For example, if we speak -Lights ON-, then the module will turn the lights on. If you plan to make project for your college than you can configure this only for ON/OFF switching by speaking ON or OFF.
I hope that you will get clear idea about this.

*Voice encryptor & decryptor (can be used for secure voice communication)>
This is very good project according to me. We have to just convert the voice to the digital signal, than by using the hashing algorithm or any other encryption method we have to encrypt the digital signal & than transmitt it towards reciever. Same way decryption process is done on receiver side.
