Letter sounds and letter names: why be-a struggles to become ba
The spelling method starts with letter names: be, a, em, es. Asked to read the word baba, a child says be-a-be-a and then has to turn four names into two syllables. That translation step is where many children stall halfway through a word, stare at the card and guess. Letter names carry extra sound with them: be has a vowel trailing after the consonant, em has one in front, and that extra vowel sneaks into the blend when the child tries to put the word together.
The sound method, known in most books as phonics, cuts out that step. The letter b is introduced as a short /b/, the letter a as /a/, and when the two are said quickly one after the other, the child's ear hears ba straight away. Indonesian suits this approach well because its spelling is regular: a given letter is read with almost the same sound wherever it sits in a word. The exceptions are few, mainly the two sounds of the letter e and pairs such as ng and ny, and each one gets its own stage later in the sequence.
Letter names still have their place; they simply come later. Once a child blends syllables with ease, names can be learned as labels, handy for talking about letters while writing their own name or singing the alphabet song. In the early weeks the adult helping sticks to sounds only, even when pointing at letters on a shop sign or a snack wrapper, so the child works with one consistent system.
In the early stage every letter is introduced by its sound; letter names follow once the child blends syllables comfortably.
