> **Quick answer:** SpeakStar is a free English pronunciation trainer for Vietnamese children aged about 4 to 10 that scores every spoken word on the device. It's made for Vietnamese parents who want their young child to practise speaking English, on iPhone and iPad (coming soon to the App Store). SpeakStar is free, with no ads, no in-app purchases and no subscription.

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

- **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

1. **Set up in a minute** — A nickname, an English name picked from a list, and an age. No email, no password, no account.
2. **Tap the mic and speak** — The child reads the sentence out loud; the app shows which words came through and awards stars.
3. **Practise the hard sounds** — Jump to any of the 44 sounds, watch the mouth, hear the reference, and try the practice sentence.

## Privacy

SpeakStar is built by Sakura5 and is made for children, so this page is written for the parent. The short version: SpeakStar collects nothing, tracks nothing, shows no advertising, and makes no network requests of its own — there is no URLSession in the app, no backend, no analytics SDK, no advertising SDK, and no third-party SDK of any kind. It is free, has no in-app purchases, and needs no account. All 476 audio recordings are bundled inside the app, so it works with the internet switched off entirely — which is how we would suggest you let a child use it.

- Nothing about your child reaches us. The app's privacy manifest declares no collected data types and no tracking, and there is no server for it to send anything to.
- Your child's nickname, the English name they picked, their age, their level and their star count — stored locally in iOS UserDefaults on the device, and removed when the app is deleted.
- The most recent recording — written to a single temporary file on the device (“last-take.caf”) purely so your child can play back what they just said. It is overwritten by the next attempt and is never uploaded.
- Microphone audio while the mic button is held — passed to Apple's Speech framework on the device to be turned into text, then discarded (see “Speech recognition never leaves the device” below).

## FAQ

**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.

**Who makes SpeakStar?**

SpeakStar is made by Sakura5, an independent app studio that builds focused, privacy-first apps for iPhone, iPad and Mac. Support: support@sakura5.app.
