Changeable voice message audio out

Projects General Guidance
1

Hi,

I'm brand new to Arduino and am very excited about working with this environment.

I have a ham radio repeater and would like to be able to play easily changed (recorded) voice messages at a programmable interval.

Just to be clear, the project will output every some number of minutes an 8 ohm audio/line level signal of a voice message while holding a transmit line low. Would be best if the played message originated in text form and sent remotely to the project.

Anyone have any ideas?

Thank you,

Joseph

You'll need an [u]audio shield[/u] to store MP3 or WAV files and for it's digital-to-analog converter. Then, you'll need an audio amplifier to drive the 8-Ohm load.

The Arduino doesn't really have enough processing power to "change a voice" (at least not in real time).

Would be best if the played message originated in text form and sent remotely to the project.

The Arduino isn't powerful enough for text-to-speech either... :frowning:
