I work for Voci, they produce high-performance speech recognition engine. If you are looking for an all-round ASR solution for your product, I recommend you to talk with Voci's representatives.
Aside from work, I am happy to help on matters in deep learning, natural language processing and computer vision. You can search for me at LinkedIn, Plus or Twitter. Though if you need advice or consultation though I would suggest you to talk with me through my clarify.fm account.
(I would strongly recommend not to Facebook PM me. The volume (5 requests/day) is just too much for me to handle..... )
