Abstract
The project aims at designing a system to guide the aged people by announcing the name of the thing requested by the user using voice alert and IR technology. The system contains control systems, manipulators, power supplies and software all working together to perform a task.
The system accepts the input from the user’s voice. The voice IC interfaced with the microcontroller allows the system to store a good number of messages. Thus, the system initially stores the voice messages using the IC in the record mode. Each message will be assigned with a unique number.
Thus, in the play mode, when the user presses a particular number from the IR remote, the IR receiver in the system receives this input and passes the data to the controller. Thus, the controller reads this number and compares this number with the already saved data. If this number matches with any of the stored data, the system plays the word stored under this particular number and this can be heard through the speaker. If the number, given through the remote, does not match with any of the stored data, the system simply says that it is an error.
The system also allows the user to record and play the messages at any time. If the user wants to record a new message, he has to erase any of the already stored messages if the memory of the voice is full.
