Some believe that this is about vocalizations. But vowels will appear almost a thousand years later.
We are talking about the smallest Hebrew letter י (yod) - this is the floor of the vertical bar.
Letters also consist of dashes, the presence or absence of which can change the letter, for example.

In the example, we write MILKO and say MALAKO.
So why write vowels if we already know how to pronounce correctly?
Another thing is that for hundreds of years the Jews have been speaking a different language, even other languages, because they have scattered all over the world.

So we decided to create notes to clarify vowel sounds.

It should be understood that vowels are rather not vowels that were simply added, they rather resemble transcription, as in English.
In English transcription there are sounds O, O open, A, A open ...
Here too there are a few A's, a few E's.

English sounds of their voicing

O – אֹ – אוֹ - a dot at the top left corner of a word.
    example: שָׁלוֹם‏‎ - (shalom) - peace, tranquility, greeting

U – אוּ - אֻ - slanted points, and when using the letter VAV - a point in the middle.

E – אֵ - אֶ - אֱ - horizontal dots.

I – אִ - אִי - one point down.

' – אְ - two vertical dots - no vowel.
    example: שֹׁומְרוֹן (Shomron) - Samaria.
