Hi
I am interested in making a jacket that simply amplifies the wearer's voice. I have used a lilypad arduino for projects in the past but have never attempted any sound projects. I would like to use a kind of woven or embroidered speaker on the jacket to allow the person who is wearing it to speak loudly in front of an audience.
Does anyone know of a lilypad project that amplifies the voice through a soft circuit and lilpad?

thanks

No you can not do this with a digital controller. You need the signal to be 5V peak to peak before you can input it and by the time that is done there is nothing left for the arduino to do.

I know that it is possible to make soft circuit speakers using fabrics and the lilypad, what device would have to be connected to this circuit - a small microphone? I'm thinking of the kind of mike that professors might use in a lecture hall.

Can you post a link so I can tell what you mean. The words you use are strange and not engineering terms.
Any microphone just produces a very small signal, this needs to be amplified. You can not do this with just an arduino.

yes I am pretty new to arduino- here is a link that might help http://www.kobakant.at/DIY/?p=3794
