Let us we divide all the letters in 3 large hypergroups
1. פמב
labial
2. לזסנטשדרצת all, that
need fore-tongue
3. כחעקג
all, that need back-tongue and
throat
Now let us examine statistic of the hebrew roots in our
database regarding all the combinations of 1.2.3. without repeating (such as
1.2.1.)
The difference in quantities of the letters in each group
(3,10,5) should not influent on the statistics because we take only combinations
where all groups are present.
It is convenient to take one letter from each group as a
notation: 1=P, 2=T, 3=K. It also would be useful
considering our speed/conveniency-test for each triad. In fact
each triad combination of letters P,T,K represends caracteristic movements of
all according roots. For example pronouncing KPT you make the similar movement
of pronouncing גִּבֵּשׁ , גָּמַר חָמֵשׁ
and so on.
Here is the statistic:
............................................................
312 KPT
[כחעקג][פמב][לזסנטשדרצת]
57
This "root"-statistic stickingly differs from that of "hole-text"-statistic.
Here is the triplet statistik for humash:
SORTED 3
PKT=3055
TPK=2944
PTK=2675
KTP=2496
TKP=2252
KPT=1916
SORTED 2 TWO 2
PT=17692
TP=16401
KT=15914
TK=13164
PK=6537
KP=5553
*This results were also tested with "random words"
method, so the influence of words conjunction on the statistics was expluded.
Other TaNaKh texts give very close statistics.
Here we can see, that most "inconvenient pair is KP. If you try to speek
very quick KP and than PK you will notice, that PK is much easier to pronounce,
due to the "opening-mouth" movement.
But difference in PK>KP statistic can not explain the difference of triplets
with PK, KP pairs : PKT=3055/KPT=1916 ~= 3/2 but K=6537/KP=5553 ~= 6/5.
As we see, words-statistics of phonetic contour reflect conveniency of pronounciation.
