Hello Everyone
I wonder if you know any Syllables pronunciation extension or service provider , for example
Hello --> Hell-O
Carpenter --> Car-Pen-ter
which makes this service as well can let's say understand it via recording it with microphone

This is difficult. Not aware of any extension that can do this with App Inventor.
A possible Python solution Don https://www.researchgate.net/post/How-to-automatically-cut-words-into-syllables .

so it's beyond app inventor computational power , mmm i was thinking of innovative app which is based on that idea but it seems it need plenty of minds , one mind & two hands can handle it alone 
AI2 can probably do it, you would just have to write the algorithm, or create a database of words and their syllables.

i do understand , anyway i have question off the topic regarding the database of words , let's say if i want to convert mysql db or i already have sql file for tables creation and i want to convert one column into a list or the whole db into tinydb , is there a tool created for this yet or i shall insert it manually one by one 
This might give you some ideas....
it doesn't have to be about Google Sheets or SQLite, the processes are similar for most requirements....

With javascript and AppInventor it can be done quite easily.
Just use a regez inside a script.

Hmmm, not working here in companion?
I tested in companion on Android 11 and Android 10 works fine
Image Is screenshot of companion
Works OK (companion) on real device, Android 12, but not on my genymotion Android 10. Don't know why, javascript usually runs OK, I'll keep digging...
[EDIT] Doesn't work with customWebView either, so there must be a glitch in the emulator somewhere for regex.
[EDIT 2] Fixed it 
It wasn't the regex, but the .replaceAll javascript function:
replaced it (excuse the pun) with
and it works

Is it possible to apply the regex to your regex extension, so one could build a procedure using just blocks?
const syllableRegex = /[^aeiouy]*[aeiouy]+(?:[^aeiouy]*$|[^aeiouy](?=[^aeiouy]))?/gi;
You are right.
Android webview doesn't support not standard
ECMA script and replace all function Is a prototype function
.replaceAll works in modern browsers and in Android 10,11,12 on real devices, it just may not be backwards compatible with older devices...
In Spanish, syllabic separation is a bit more complicated, since many words have vowels with accent marks.
I have used this JavaScript code to get the Spanish syllables:

BTW, what is the hyphenation of the word ridiculous, ri-di-cu-lous or ri-dic-u-lous?
https://www.silabas.net/index-en.php?lang=%2Findex-en.php&p=ridiculous&button=Hyphenation
I would say this one (which Marco's algorithm returns)
Try rhythm or righteous
sorry I don't understand, do you want a block with this pattern? the MATCH or REPLACE function not working ?
edit: it's working:

I couldn't get it to work at first, but realised some editing of the regex was required:
[^aeiouy]*[aeiouy]+(?:[^aeiouy]*$|[^aeiouy](?=[^aeiouy]))?
worked for me :)
