I am planning on implementing a human voice discrimination system on a board. Just for fun. I have already implemented such algorithms before, and their performance is fine.
Before I figure out how to implement something like that on hardware, I want to purchase a decent board <$300 to accomplish the project. I am determined to figure it out. I just want someone with experience to tell me if ZYBO Z7-10 be enough, or if I should purchase the ZYBO Z7-20. Link to the product here. If neither of these may be enough please do suggest anything better.
Thank you for your inputs.
