Why do I add extra vowels, like 'eschool' for 'school'?

Because your first language has rules about which consonant sequences are allowed to start or sit inside a syllable, and English keeps breaking those rules — so your mouth applies the same automatic repair it would use on a borrowed word in your own language: insert a vowel to make the sequence pronounceable.

30-second version: Linguists call this epenthesis, and it's genuinely rule-governed rather than random. Spanish and Portuguese speakers insert /e/ before an initial /s/-plus-consonant (school → "eschool"), because that exact sequence is forbidden at the start of a word in those languages. Japanese speakers, whose language allows almost no consonant clusters at all, insert vowels much more broadly — black can come out with a vowel after nearly every consonant. Different source language, same mechanism: a syllable structure that isn't allowed at home gets automatically repaired the moment it shows up in English.

Why this shows up differently depending on your first language

The specific pattern depends entirely on what your first language's syllables allow. If your background is Spanish or Portuguese, the pattern is narrow and predictable: it fires specifically on word-initial /s/ followed by another consonant — student, special, Spain, sport — because that's the one sequence those languages actually forbid. That case is common enough, and specific enough, that it has its own full treatment in the Spanish-speaker consonant cluster guide, including the back-to-front removal method.

If your background allows very few consonant clusters at all — Japanese and, to varying degrees, several other languages — the pattern shows up much more broadly, potentially inserting a vowel between almost any two consonants that touch, not just at the start of a word. Black can become something closer to "buraku," with a vowel breaking up both the /bl/ cluster and the final /k/. The mechanism is identical to the Spanish/Portuguese case — a forbidden sequence gets automatically repaired — but the scope of what counts as "forbidden" is much wider.

Why it's worth fixing rather than accepting as accent

An inserted vowel isn't a matter of accent color the way a slightly different vowel quality is — it changes the number of syllables in the word, and syllable count is one of the more basic things a listener uses to identify a word at all. Sport is one syllable; "esport" is two, and for a moment a listener is hearing a different word shape entirely, not just a differently-accented version of the right one. That's a meaningfully different category of issue from most of the sound substitutions covered elsewhere in this series, and it's part of why this specific pattern is worth isolating and fixing directly rather than treating as personality.

How sayit catches it

An inserted vowel shows up in the alignment as an insertion — a phone appears in your recording with no corresponding phone in the target word's canonical IPA at all. Because it adds a full extra syllable rather than just shading an existing sound, it's one of the more clearly-flagged error types in the breakdown, distinct from a substitution (wrong sound in the right slot) or a deletion (missing sound). The breakdown will show exactly where in the word the extra vowel landed, which tells you whether the pattern is narrow (always before initial /s/-clusters) or broad (showing up between many consonant pairs).

What the fix looks like

The core technique, regardless of which pattern is yours: if you need extra time to prepare a consonant cluster, lengthen an existing consonant rather than inserting a new vowel — a held "ssss" before "student" is a normal English sound and vanishes once the cluster is stable; an inserted /e/ is a new syllable that a listener will count whether you meant it or not.

Drill it

Record: "A student from Spain speaks Spanish." Four words with the initial /s/-cluster pattern, useful whether your pattern is narrow or broad, since it's the single most common trigger across language backgrounds.

How do I know it's improving?

Count syllables, not just clarity. Say the target word, then count on your fingers how many syllables you actually produced, and compare it to the correct count. This simple check catches the pattern even on days when the recording "sounds fine" to your own ear, because an inserted vowel you've heard your whole life is easy to stop consciously noticing.

Try it

Open sayit free — no install, no card — and record the drill sentence above. If any word shows an insertion, count the syllables out loud against the target before your next attempt — that simple check is often more useful than the score alone.
