SpeakStar is a Vietnamese-language English pronunciation trainer for children roughly 4 to 10. 24 lessons, all 44 IPA sounds, read-aloud passages and six sing-along songs — the child speaks into the mic and every word is scored on the device. Free, no ads, works offline.

What it does
Everything you need, nothing you don't.
Say it and be scored
The child taps the mic and reads the sentence aloud. Each word is coloured — heard, nearly heard, or not heard — with 0 to 3 stars for the attempt, all worked out on the device.
24 lessons, four levels
Each lesson: listen to a short dialogue, say every sentence and get scored, then read a short passage aloud. The child moves up levels at their own pace.
All 44 English sounds
A full IPA chart with an animated mouth, and one practice sentence loaded with each sound. The reference recordings are by phoneticians, not a text-to-speech voice.
Read aloud and sing along
Read-aloud passages and six short songs with word-by-word highlighting — both work with no microphone at all.
Vietnamese throughout
Every instruction, label and translation is in Vietnamese, so a child can use the app without a parent translating each screen. The material being practised is English.
Nothing is collected
No account, no ads, no analytics, no third-party SDKs, no network requests. All 476 recordings are bundled, so the whole app works with the internet switched off.
How it works
Set up in a minute
A nickname, an English name picked from a list, and an age. No email, no password, no account.
Tap the mic and speak
The child reads the sentence out loud; the app shows which words came through and awards stars.
Practise the hard sounds
Jump to any of the 44 sounds, watch the mouth, hear the reference, and try the practice sentence.
SpeakStar FAQ
Straight answers about price, devices and privacy.
Does SpeakStar collect anything about my child?
No. There is no account, no advertising, no analytics and no third-party SDK, and the app makes no network requests of its own. Nickname, age, level and stars stay on the device.
Does my child's voice leave the device?
No. Speech recognition is forced to run on the device on every attempt; if a device cannot do on-device recognition, SpeakStar refuses to open the microphone instead of sending audio anywhere.
Can we use it without the microphone?
Yes. The read-aloud section and all six sing-along songs work without the microphone.
Is SpeakStar really free?
Yes — no in-app purchases, no subscription, no ads and no trial. All 476 recordings are bundled, so it also works offline.
