When I studied Gregg Shorthand
http://gregg.angelfishy.net/analphbt.shtml , I learned there were 12 common vowel sounds used in the system. These vowel sounds aren't universally represented by the same letters. Sometimes "A" may represent a particular sound, and sometimes "E" instead may be used for that sound.
Letters (representing both consonant and vowel sounds) in English themselves have a ranking in terms of frequency of usage

That's my request. Is there some list of vowel sound frequency ranking? I mean the sounds, not the letters.
The reason I'm asking is that I'm learning this number memory system
http://academictips.org/memory/noshape.html . Using this technique requires assembling consonant frameworks and filling-in the frameworks with meaningless vowels. For easier recall, the article suggests using the same pattern of vowels every time, and it offers the standard "A" as a first choice, followed by "E" etc. (AEIOU-Y). That's a pattern I could use, but I'm thinking about using the most frequent first and so on down the line. In that way, I would be more likely to hit upon real words.
