Have you seen this post?
There is an Anki deck and video there.
From a quick look at the chart, I wonder if you could create a memory palace for the columns:
- bilabial
- labiodental
- linguo-labial
- etc.
Each of those locations would be the starting point of another memory journey (or peg list) to handle the rows. Each of the sub-journeys could have 14 locations (or pegs), some of them empty.
So the first column (bilabial), might be something like:
- nasal -- m̥ m -- it's kind of intuitive, if you think about it. What is the nasal sound (sound only comes through the nose) that involves both lips ("m")
- stop -- p b -- it's intuitive here as well. What are the sounds that stop the flow of air and involve both lips? (p and b)
- etc.
The first location in each sub journey (or peg list) would always be a nose (nasal). The second would always be a stop sign (stop), etc.
I haven’t done it but am just brainstorming here. If what I wrote doesn’t make sense, I could write out the idea in more detail.
