Hope this is the right place, if not feel free to move the thread...
I am building a project using an EasyVR speech recognition shield https://www.sparkfun.com/products/10963? for control input.
I am likely to be using the item in a high-noise environment, so I would like to use a "throat mike" in place of the little microphone that comes with the kit.
According to the EasyVR manual, the microphone is fairly fussy, and they don't support anything other than the included mic, that is (IMHO) totally unsuited for the project. I found there are huge numbers of throat mikes on eBay (as just a first starting place to look) with most listings saying what radios they work with, but not necessarily what the actual specs on the mike are.
Per the Easy VR manual, the mike needs a 38dB sensitivity (0dB=1V/Pa @1KHz), 2.2Kohm load impedance, 3V operating voltage, and a nearly flat frequency response from 100Hz - 20KHz. I don't really need audio output, but most of the mikes seem to have a built in speaker, so the EasyVR output specs are either 8ohm speaker terminals or a 16-32ohm headphone jack.
Can anyone suggest a suitable microphone that would work? (cost is an object, so preferably one that is reasonably priced...)
Also, the manual says that the EasyVR folks have a forum of their own, but I can't find it on their website - anyone know where it is?
