Complete List of Sounds Ch Recognizes?

Ah, D, Ee, F, L, M, Oh, R, S, Uh, W-Oo

Is the above a complete list of the different sounds that Ch attempts to recognize? Is there any effort to expand the capability?

"B" / "P" would be a good add. "B" and "P" are close enough to be interchangeable, but at present neither is available.

"K" / hard "C" - the mouth shape for "Uh" is good enough, however the problem is that Ch thinks a "K" sound is an "S".

"H" - is mostly air, on my voice, Ch analyzes "H" differently almost every time. Sometimes it thinks it's an "S", sometimes and "Uh", etc.

"J" / soft "G" -  would be a good add. This is a unique mouth shape, with a tongue move.

"N" - would be a good add. This is a unique mouth shape, with the upper lip doing a nose crinkle, and a tongue move.
