Voice Recording and Play Back Circuit using APR9600

I edit and author this site. I voide the Apr After compilation, the machine source code is converted into hex code which is to be dumped into the microcontroller for further processing.

The procedure is the same as described above in MOD8, and the keys available in this mode are M1 to M4. Proteus is a programmer which itself contains a microcontroller in it other than the one which is to be programmed.

This paper describes the concept using a microcontroller based system. Keep the sampling rate preset PR1 in the middle position to test a sample of the recorded message. Microphone amplifier, automatic gain control AGC circuit, intends anti-aliasing filter, integrated output amplifier and measure management etc. All normal C data types are supported along with pointers to constant arrays, fixed point decimal, and arrays of bits.

My requirement is to record four different sound in one circuit and play any one sound when i want.

When we finish recording, the selection button is released. The replayed sound exhibits vlice quality with a low noise level. This information is provided by the GPS with the help of the data it receives from the satellites.


60 seconds Voice Record – Playback module – Electronics-Lab

Now when the blind person enters these regions loca- tions with this system the voice module will announce the location names as we had recorded them with respect to the stored locations. There are basically four families of PIC microcontrollers: We just have to make sure that the distance between the two locations is greater than meters.

Recorded sound is retained even after power supply is removed from the module. How can i help you? While still holding the selection button, we can record a 5sec message. Connect a appropriate speaker should not lower than 8 Ohms at LS1, For playing a recorded message you just need to press and release any of the switch available in that particular mode once.

Electronic Game and Fun Projects. Leave a Reply Cancel reply. This project is a 60 seconds voice record — playback module. The first phase would involve recording of the voice in the voice module. Abstract — GPS is employed to find the position of the user on the earth. Proteus is a software which accepts only hex files. After getting voicr 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.

Google Plus and Facebook. Vpice storing the location swe need to restart the system. It consists of 6 pins from A0 to A5 Port B: Gener- ally, we put power traces on the top of the board, jump- ing only to the bottom if a part cannot be soldered onto the top plane like a relay vouce, and vice- versa. It is also possible to control the IC using external digital circuitry such as micro- controllers and computers.

According to the datasheet, if you press and hold the message button M1-M8 the message is replayed repeatedly. According to sample frequency selected for recording, inter anti-aliasing is automatic adjusted voicr response.

There are various types of voice processing chip IC with various features for speech compression and processing is readily available. Can you help me? In parallel access mode, sound can be rec- orded in 2, 4 or 8 sections. It should be noted that if a trace is running on the top layer, check with the components to make sure you can get to its pins with a soldering iron.

Pin 1 is MCLR master clear pin pin also referred as reset pin. This system has been successfully designed and tested using the PIC16F microcontroller. When the satellite signal is receieved by the GPS, the latitude and longitude of the current location is displayed on the LCD. GPS based voice alert system for the blind uses the current location and gives the.

However, by changing an oscillation resistor, a sam- pling rate as high as 8. For this, we have to switch ON the voice module by connecting the power supply batte- ries.
