The total number of vowels is seven: אֹ ,אִ ,אֵ ,אֶ ,אַ ,אָ and אֻ. From within these seven vowels the letters ו ,ה ,א, and י are pronounced. From qameṣ, pataḥ and segol ʾalef and he are pronounced, as in עַמֶּיךָ ,עֲבָדֶיךָ and קָשֶׁה. If the he (in קָשֶׁה) were elided, the segol (by itself) would indicate its existence, just as the qameṣ in עַמְּךָ ,שִׁמְךָ and עֲבָדֶיךָ indicates the existence of ʾalef or he in full orthography ... Ṣere and ḥireq indicate the existence of yod, as in עֵינִי, since the yod is frequently written defectively but these two vowels indicate its existence.
