Multilingual Teleprompter App: Offline Voice Scrolling by Language

Displaying a language and following it are different problems

A teleprompter that shows Japanese text is doing something a text editor does. A teleprompter that scrolls when you speak Japanese has to recognise Japanese speech — and that capability is added language by language, which is why so many apps advertise voice scrolling and then quietly limit it to English.

So there are two questions worth asking separately about any app you are evaluating:

Does it display my script correctly? Right-to-left scripts like Arabic, and scripts without spaces between words like Japanese and Thai, are where cheap implementations break.
Does its voice feature work in my language? This is the one that usually comes back "English only".

If you are new to voice scrolling generally, the voice-activated teleprompter explainer covers how it differs from a fixed scroll speed.

Language support on iPhone, iPad and Mac

On iOS, Voice Sync AI supports English, Chinese, French, Russian, Bengali, Spanish, German, Korean, Italian, Portuguese, Indonesian and more locales, plus Japanese — which works on any iOS version, including older iPhones and iPads. The Mac build ships on the same App Store listing, so the coverage carries across.

Language support on Android

Android now carries the full catalogue: 21 offline packs covering 22 languages, exactly the same set iPhone, iPad and Mac get. Twenty are single-language — Bengali, Catalan, Chinese, Czech, Dutch, English, Farsi (Persian), French, German, Hindi, Indonesian, Italian, Japanese, Korean, Polish, Portuguese, Russian, Spanish, Turkish and Vietnamese — and the twenty-first is the multilingual pack, which covers Arabic, Chinese, English, Indonesian, Japanese, Russian, Thai and Vietnamese in one download and is the offline route for Arabic and Thai.

Japanese voice scrolling on Android and iPhone

This is the question we get asked most often by name, so here it is directly. If you are looking for an Android teleprompter app that supports Japanese voice, Japanese comes through the multilingual pack rather than a standalone Japanese download. Grab that pack and you get Japanese along with seven other languages, without picking one up front.

Three things worth knowing before you rely on it for a shoot:

It works on every iPhone and iPad, not just recent ones. There is no iOS version requirement for Japanese — older devices are covered by the same pack.
It runs offline. Download the pack once and Japanese voice scrolling keeps working with no connection, which matters if you shoot on location or in a studio with unreliable wifi.
You do not have to choose up front. Because Japanese ships inside the multilingual pack, switching between a Japanese take and an English or Chinese one needs no download between takes.

The multilingual pack in practice

One download, eight languages: Arabic, Chinese, English, Indonesian, Japanese, Russian, Thai and Vietnamese. It is live on iPhone, iPad and Android.

It earns its place in two situations:

You record for more than one market. Shooting the same product explainer in English, then Japanese, then Vietnamese means no pack-switching between takes.
You do not know in advance what you will need. Booked for a shoot where the client may want a Thai version — the coverage is already on the device.

And because it works offline like the rest of the packs, none of that depends on the venue having usable wifi.

Why offline matters more outside English

There is a fuller treatment of this in what actually keeps working with no internet, including a thirty-second airplane-mode test worth running on any app before you depend on it.

Offline support is a convenience for an English-speaking creator recording at home. It is frequently a requirement for everyone else, because the shoots that need a second language are often the ones with the worst connectivity: a conference floor, a client office abroad, a hotel room on a paid-per-device network, a location with no signal at all.

In Voice Sync AI, speech recognition runs on the device on iPhone, iPad, Mac and Android. Download a language pack once and voice scrolling keeps working with no network connection at all. The side effect matters too: an unreleased script for a client in another country never leaves your phone.

Scripts that mix two languages

The most common version of this by far is Chinese switching into English for a product name or an acronym, which has its own guide covering Mandarin scripts and the bilingual option.

Bilingual delivery is its own case. If your script switches languages inside a sentence — common in Chinese-English business presentation and in a lot of tech content — there is a Chinese and English bilingual option built for exactly that.

For switching between takes rather than mid-sentence, the multilingual pack is the simpler answer: you are not asking the app to handle a mixed line, just to cover both languages.

Writing scripts in a second language

Two adjustments make a non-English shoot go better, and neither is about the app:

Write it spoken, not translated. A script translated from English tends to keep English sentence rhythm, which is hard to read aloud naturally and makes for a stiff take. Draft in the target language where you can, or have a native speaker rewrite rather than translate. The principles in how to write a teleprompter script apply in any language.
Budget different word counts. Speaking rates vary by language — the same 90 seconds of content is not the same number of words in English, Japanese and Spanish. If you have a hard runtime, time a read rather than trusting a word count. Our scroll speed guide covers how to measure yours.

Setting up a language pack

Open language settings in the app and download the pack for what you will speak — or the multilingual pack if that is several things.
Download over wifi before you travel. This is the step people skip and regret on location.
Load your script and read a few lines to confirm the prompter is following before the first real take.
Position the device on the camera axis as usual — see the iPhone teleprompter guide for placement and second-screen setups.

Frequently asked questions

Is there an Android teleprompter app that supports Japanese voice?

Yes. Android has a dedicated Japanese pack, and Japanese is also one of the eight languages in the multilingual pack — a single download covering Arabic, Chinese, English, Indonesian, Japanese, Russian, Thai and Vietnamese. Both run offline once downloaded, and both are live on iPhone, iPad and Mac as well as Android.

Which languages does Voice Sync AI support?

Voice scrolling runs offline in 22 languages, and the list is the same on iPhone, iPad, Mac and Android: Arabic, Bengali, Catalan, Chinese, Czech, Dutch, English, Farsi (Persian), French, German, Hindi, Indonesian, Italian, Japanese, Korean, Polish, Portuguese, Russian, Spanish, Thai, Turkish and Vietnamese. Twenty have their own free pack; Arabic and Thai come through the multilingual pack, which covers eight languages in one download.

Does voice scrolling work offline in other languages?

Yes. Download a language pack once and voice scrolling keeps working with no network connection at all, on iPhone, iPad, Mac and Android. Your scripts stay on the device.

Can I use a script that mixes two languages?

There is a Chinese and English bilingual option for scripts that switch between the two mid-sentence. The multilingual pack also covers eight languages at once, which helps when you switch languages between takes rather than inside a single line.

Do I need a newer iPhone for Japanese?

No. Japanese works on any iOS version, and the multilingual pack works on older iPhones and iPads too.
