HELP!! how to use DTMF Auto dialer for security system project..

My project objective is:
Must dial out a restored and deliver an emergency message stored in the speech IC..


i dunno how to start my project because my objective required a dial out voice message..

no one help me? T.T

hi

try this **broken link removed**

it also has many other dtmf dialer ic nos.

but how to stored voice in IC and send it to telephone ?

It is a DTMF decoder, To dial out a number you should have an encoder

First of all you need a microcontroller to do this job.

You may try MT8888 Which can do the both or else you can generate DTMF with micro itself.

For voice recording and play back you can use APR series chips.

Best of luck

sorry my mistake.

 

[shawnjames]

from the emergency signal use relays to encoder the particular sequence or the signal and the output of this encoder must be given to the decoder...

can u give me the link example of the dtmf auto dialer with voice connection circuit?
because i having big problem in the connection of circuit..i dunno what should i need in the circuit..
the programming part i can try to do it myself..

and can i use APR9600 to send the voice out ?

 

[mishra12]

yes you can use 9600 as voice out put see here https://www.edaboard.com/threads/197758/#post843376 for circuit

thanks for ur reply...
if i using apr9600 what IC should i connect ?
i mean for my project DTMF Auto dialer with voice..

some ppl ask me using MT8880 , MT8888..
when i go through the datasheet..i really confuse - -"
i am confusing dunno which circuit should i to connect...
any suggestion ?

Have a look in "Special Function - Voice Record/Playback"
at: Special Function IC's - Others
Connect IC to appropriate MCU as per IC data sheet.
Hope ths work.
