Chat bot Within Unity using Amazon Lex

I'm currently working on a project that requires that we hook up Amazon Lex with Unity, we want to have chat bots that you can communicate with using voice commands. I'm having a hard time finding precisely where to start and I was wondering if anyone around has worked with this stuff before.

Seems like the Amazon AWS SDK doesn't support Lex, or I just haven't figured out how it supports Lex.
The alternative to an SDK would be to have the chat bot hosted on a Web API and then use UnityWebRequests to communicate with the site, but then there's the issue of sending a sound file to this site. What would be a good way of sending voice info to the site without having to record the sound, save it, send it, and then play it again for the bot?

I know Amazon has their own Unity equivalent that supports Lex natively, but we don't want to deal with Amazon pay walls.

Any help would be appreciated!
