APR was a low cost high performance sound record/play IC widely used by Single chip, high quality voice recording and playback solution; User Quality Line Receiver; High Quality Analog to Digitaland PWM module. Voice Module 60 Sec project will playback and record up to 60 seconds of voice message. This circuit is an This circuit is based on APR IC from Aplus. General Description. The APR devi ce offers true single-chip voice recording, non-volatile storage, and playback capability for 40 to 60 sec- onds.

Once the machine code is converted into a hex code, that hex code has to be dumped into the microcontroller and this is done by Proteus.

PIC compiler also supports C language code. Hi, I am apr96600 miniature railway model and I need similar circuit in which I can play pre-recorded horn by pressing button.

To record a message in any on of this location, you need to keep the Record Switch SW10 pressed with one finger and the Segment Switch voics. Then, using a push button and different selection buttons we record the voice. Check on this website http: One of the limitations being function recursion is not allowed. This system has been successfully designed and tested using the PIC16F microcontroller.

A device or system that supplies electrical or other types of energy to an output load or group of loads is called a power supply unit or PSU. This project can be extended by incorporating a GSM module. Complete Electrical Symbol 3. This device is designed to provide a voice based an- nouncement for the user, i. Since we are using eight se- lection buttons in this system we can record eight differ- ent voice messages. After compilation, the machine source voics is converted into hex code which is to be dumped into the microcontroller for further processing.

While still holding the selection apg9600, we can record a 5sec message. For anyone with a GPS receiver, the system will provide location and time. Gener- ally, we put power traces on the top of the board, jump- ing only to the bottom if voicee part cannot be soldered onto the top plane like a relayand vice- versa.


60 seconds Voice Record – Playback module

Presence of every module has been reasoned out and placed carefully, thus contributing to the best working of the system. After the suc- cessful compilation of the program, it is dumped into the microcontroller using moduule dumper. It consists of 8 pins from C0 to C7 Port D: After getting the signal, if we want to store the present location as an alerting location for the blind person, the following procedure will do the needful — i.

There are various types of voice processing chip IC with various features for speech compression and processing is readily available. This microcontroller has a program in it written in such a way that it accepts kodule hex file from the PIC compiler and dumps this hex file into the micro- controller which is to be programmed. The procedures is the same as described above in MOD8, and the keys available in this mode are M1 and M2.

This project would be a great fit for your railway model.

APR9600 Voice Recording Playback Module Support Single Chip

This paper describes the concept using a microcontroller based system. I have the Apr I edit and author this site.

The locations names are pre vooce in the voice circuit and are announced when the person reaches those particular locations. The given voice signal and first sampled and then the corresponding instantaneous voltage samples are stored in the non-volatile flash memory cell in 8-bit binary encoded format. This circuit will help you record and play a 60 seconds voice message stored on it.

Doing so, we can track the movement of the Blind person in a very efficient manner. Single sided boards are cheaper to produce and easier to etch, but much harder to design for large projects. Proteus is a programmer which itself contains a microcontroller in it other than the one which is to be programmed. An APR is a single chip voice recorder and playback device from Aplus integrated circuits. Not only is a proper PCB neater but it is also more durable as there are no cables which can yank loose.

Proteus is a software which accepts only hex files. The recordable sound is changed to voice signal using microphone and given to IC 1 through differential amplifier. When modhle finish recording, the selection button is released. Active data means, when the GPS receiver gets the satellite sig- nal it will give the current location values.


Bread- boards are great for prototyping equipment as it allows great flexibility to modify a design when needed; howev- er the final product of a project, ideally should have a neat PCB, few vokce, and survive a shake test. My requirement is to record four different sound in one circuit and play any one sound when i want.

Pin 1 is MCLR master clear pin pin also referred as reset pin. When using a double sided board we must consider moddule traces should be on what side of the board.

The working of the system can be divided into two phases. Once the ic starts playing will it be playing again and again itself or it will stop after playing the recorded music 60 sec.

Next, we show the GPS to the open sky for receiving the satel- lite signal. The first phase would involve recording of the voice in the voice module. Electronic Game and Fun Projects.

Low voltage, low power DC power supply units are commonly inte- grated with the devices they supply, such as computers and household electronics. There is a simple process involved in recording these eight messages.

Voice Recording and Play Back Circuit using APR – Best Engineering Projects

The system designed consists of a GPS receiver and a voice circuit apr9600 is interfaced to the microcontroller. The project provides four different modes of voice message to be recorded and played, viz i MOD8: Here instead voicw an alarm sound the blind man can directly hear the location rec- orded by the user itself.

It stores the data of the current location which it receives from the GPS system, so that it can make use of the data stored to compare with the destination location of the user.
