Hello. This is Alireza. I am the founder of Picovoice.
I totally understand the need to support makers community. We do have GitHub repositories for engines demoed here which allows you to use these technologies to some extent (not the full set of capabilities). I am working with our partners (both Soc and distribution) to come up with a maker-specific product for evaluation and personal use. It most probably will be a HW/SW product (i.e. a board that comes with our software). The product should allow you to use the full set of features on that specific board. I am expecting this to happen in 2019 and I will disclose the information as I am figuring things out.
