General

I got the easyVR board and immediately discovered that I needed the development board to really use the board effectively. No problem, another 15 bucks. It took a while to figure out the software but you can do it in an hour or two and have an arduino uno recognizing speech words.
The main shortcoming of the system is background noise, which is a problem with all speech recognizers. The system would not recognize while I had the window air conditioner running in the room. With the room dead silent the unit is very good. The unit has AGC that will take whatever background noise there is and put it to a reference level. So even fairly low volume background noise will interfere with the recognition.
A second problem seems to be the AGC adjustment to the voice input. I found that the unit would not recognize after ten minutes or so. After I spoke several words it began recognizing and was then accurate. Seems to take a bit of speech for it to get the volume level correct.
The last problem I found is that there are some words you cannot program. It refuses to accept words in its internal vocabulary for some reason. This can be a real hassle if you need only a number or two and not the whole range of numbers. Using the entire built-in library of numbers of course uses more of your precious memory! I guess you could go into the source code and chop out the stuff you don't want.
The supplied software generator is very clever! It will generate a compilable source code with your speech words for the arduino uno for sure, and possibly others. The code generated is heavy so you will want to chop out a lot of it in your final application to save memory, but it gives you an instant runnable program to put in your project. That is really a huge advantage for new programmers! (and for us old hats too!)
The only complaint I have with the package is the documentation, which is sort of haphazard. If you follow exactly what they show you will get results, but there are a lot of questions you will need to spend time figuring out for yourself.
