How to communicate when humanity is deaf and dumb?

This question is focused on a purely chemical messaging system for humans that provides the same degree of nuance that spoken human languages convey now as well as all the information that smells currently communicate to humans. Why humans aren't communicating by sound, touch or sight anymore is outside the scope of this question.

I'm looking for the design of a chemical library and associated signalling system that will approximate the expressiveness of human speech. This chemical library will turn into the vocabulary of this language. The mechanisms that send and read these signals from the atmosphere may be addressed though should entail as minimal changes to standard human anatomy. Assume that there's some biochemical magic responsible for synthesizing any signalling chemicals.

Not Duplicate

The cited potential duplicate question asks for a limited language in an animal. The scope of my question is for a chemical language that will convey everything that human language is capable of conveying. The scope of communication is significantly larger and for a human, not an animal.

Interesting Reading I found as I was writing this question:

These may have absolutely no bearing on the question or your answer. I include them for fun.

• Not a trillion smells
• The smell of pending death
