I modified the two versions of 黃錫凌粵音韻彙(有聲)版. The first one is based on the orignal vowels layout of Mr. Wong Sek Ling who classied the total cantonese vowels into two group, the non-entering vowels and the entering vowels. There is no classification further for the non-entering vowels as it used to be classfied into the flat, rising and going plus the high and low lones of them. This is actually good to select characters of similar vowels at that time.
Let’s take a look at the original layout:
I thought the layout still difficult to use to find the character of the particular vowels and so I layout the principals with their respective diphthongs as follows:
There are only 7 principal vowels and only 10 relevant diphthongs which are position right at the bottom of the principal vowels. For example under the aa vowel, we have the most of aai, ai, aau and au. Under i or ji vowel, we have only iu or jiu etc.
The ending vowels are shown when mouse is over the principal vowels so will not causing overwhelming effect in a visual way:
The gradual way of looking for characters of a particular syllable will be streamlined and will be logical.
The diagram illustrate the choosing of aa, then aang and the final table with consonants b,m,f… etc will be shown with their respective characters. The character will gaang with the 8th tone will be the chosen group.
