If you cannot find the email, please fill in the form below and send it to help@paddle.com.

Extract the downloaded file and place the server folder and start_voicebell.bat on your desktop.

Double-click start_voicebell.bat — the server starts and your browser opens automatically.

On any tablet, PC, or phone on the same Wi-Fi, open Chrome and enter the counter PC's IP address to connect the kitchen and kiosk instantly.

When you run start_voicebell.bat for the first time, a Windows Firewall permission popup will appear. Both Private and Public networks must be checked for kitchen and kiosk devices on the same Wi-Fi to connect. If either is unchecked, they may not be able to connect.

Windows 10 or later, 4GB RAM, and 1GB of free storage is all you need. No high-end specs required.

The counter PC (server) requires Windows 10 or later.

For kitchen and kiosk devices, Chrome browser is required. iPad, Android tablet, Mac, smartphone — any device that runs Chrome works.

Any device with Chrome installed can be used as a kiosk. iPad, Android tablet, smartphone, touchscreen PC, or a regular PC — no device restrictions.

Download the latest version from the homepage and replace the following files.

• Desktop: start_voicebell.bat
• Inside the server folder on the desktop: server.dart, server.exe, web folder

Yes, you can use VoiceBell with a laptop. Choose the setup that fits your situation.

When the counter starts, the IP address is shown automatically in the startup popup. Enter it in the kiosk browser to connect instantly.

This is normal. VoiceBell requires a secure connection to use the microphone for voice ordering.

VoiceBell runs as a local server inside your store and doesn't need an official security certificate. However, since the browser has no way of knowing this, it shows the same warning it would for any external site without one. This has nothing to do with hacking or security risks, so please proceed using the steps below.

Click "Advanced" at the bottom of the warning screen, then click "Proceed (unsafe)" to continue. This only needs to be done once per device.

The kitchen and kiosk access URLs are shown directly in the Start popup on the counter screen. Enter the URL in Chrome on your kitchen or kiosk device to connect instantly.

To find your IP address manually, go to Control Panel → Network and Internet → Network and Sharing Center → click your Wi-Fi name → Details → IPv4 address.

For a faster method, open CMD from the Windows search bar, type ipconfig, and look for the IPv4 address.

Your router automatically assigns IP addresses, so it may change after a restart.

You can fix it directly in Windows settings. Go to Network settings → your Wi-Fi → Properties → Edit IP settings → switch to Manual, enter your current IP address, and save.

You can also set a fixed IP from your router's admin page. Contact your router manufacturer or internet provider for guidance.

Please check the following in order.

1. Make sure start_voicebell.bat is running on the counter PC.
2. Make sure all devices are connected to the same Wi-Fi.
3. Make sure the IP address is correct. (Check the URL in the counter Start popup)
4. If everything looks fine but you still can't connect, your firewall may be blocking port 8444. Follow these steps to allow it.

1. Search "firewall" in Windows → open Windows Defender Firewall
2. Click Advanced settings on the left
3. Click Inbound Rules on the left
4. Click New Rule on the right
5. Select Port → Next
6. Select TCP, enter 8444 → Next
7. Select Allow the connection → Next
8. Check Domain / Private / Public → Next
9. Name: VoiceBell → Finish

Completed order data is stored locally on the counter PC. Orders added to the kiosk cart are immediately transferred to the counter and remain there even if the kiosk window is closed. However, orders that have not yet been paid will be lost if the server is shut down or the counter window is closed.

Please refer to the table below for each scenario.

There is no device limit. Any tablet, smartphone, or PC connected to the same Wi-Fi can connect.

A typical setup includes 1 counter PC (also acting as the server), 1–2 kitchen displays, and 2 or more kiosk devices.

Each device can be set to a different language. For example, the counter can be in Korean while the kiosk runs in English, Japanese, or Chinese.

Currently supported languages: Korean, English, Japanese, Chinese, French, Spanish, German, Italian, Vietnamese, Thai, and Hindi — 11 languages in total.

Go to Counter → Other Tasks (top right) → 3) Menu Management. You can enter items one by one, or upload a .txt or .csv file to register them all at once.

File format example:

To register multilingual menu names, click the Multilingual button at the bottom of the Menu Management screen. A template file will be downloaded — fill in the menu names for each language and re-upload.

Multilingual file format example (when counter language is set to Korean):

Yes. Use the up/down arrow buttons above and below the Assign label at the top of the counter screen to adjust the number of tables. Up to 30 tables can be configured.

Please check the following.

1. Make sure you have an internet connection. Voice ordering uses Google Speech Recognition and requires internet access.
2. Make sure you are using Chrome browser.
3. Make sure microphone permission is allowed. After accessing the kiosk, go to Advanced → Proceed → select a table or Auto-assign → press Start Order on the waiting screen. The browser will ask for microphone permission — make sure to allow it. If you use a fixed IP and do not clear your browser history, this only needs to be done once.
4. Make sure the device microphone is working properly.
5. Excessive background noise may reduce recognition accuracy.

VoiceBell includes the following kiosk screen protection features by default.

• ✅ Pinch zoom disabled
• ✅ Back navigation blocked
• ✅ Right-click menu disabled
• ✅ Keyboard shortcuts blocked (F5, Ctrl+W, etc.)
• ✅ Automatic fullscreen on first touch (address bar hidden)
• ✅ Automatic fullscreen re-entry if exited

Yes. You can add menu items to an order in progress from the counter and send them to the kitchen.

Orders added to the kiosk cart are immediately transferred to the counter and remain there even if the kiosk window is closed. Please handle kitchen sending and payment directly from the counter.

The cooking order is determined not by when guests first entered the kiosk, but by when they completed their order — that is, when the order number was generated. Orders are listed in this sequence on the kitchen screen.

Go to Counter → Other Tasks → 1) Payment Cancellation. Enter the admin password, then enter the order number. VoiceBell automatically retrieves the order details from the Excel file in the orders folder on your desktop. Select full or partial cancellation and confirm to complete.

VoiceBell provides a digital receipt that customers can capture by taking a photo of the screen.

When payment is completed, a receipt popup appears automatically on the kiosk screen with a prompt to take a photo. On the counter, a popup asks whether to issue a receipt for the relevant table — selecting yes displays the receipt in the center of the counter screen.

For past payments, press the E-Receipt button at the top of the counter screen, enter the order number, and the receipt will be displayed in the center of the counter screen.

VoiceBell is designed so that card payments are handled separately by default. If needed, you can connect a card terminal or POS system via Counter → Other Tasks → 8) Integration Path Service.

Currently supported integrations are as follows.
Card terminals: Stripe Terminal, Square Terminal
POS integration: KakaoPOS, TossPOS

The following two pieces of information are required for integration.

• IP address — where to send (the address of your card terminal or POS)
• API Key — authentication (the key issued by your terminal service)

The terminal and server-integrated counter PC must be on the same Wi-Fi network.

Files are automatically saved to the orders folder on the desktop of your server-integrated counter PC.

• General Excel: Desktop/orders/date_orders.xlsx (for viewing — a copy of the secure file)
• Secure Excel: Desktop/orders/secure/security_sales_date.xlsx (master record — always updated)
• Text file: Desktop/orders/orders_date.txt

While the general Excel file is open, new payments are not saved directly to it. However, they are always recorded in the secure Excel file. Once you close the general file and the next payment is made, the secure file's contents are automatically reflected in the general file.

Go to Counter → Other Tasks → 6) Email Notification Settings. You will need a Gmail account and a Gmail app password.

How to get a Gmail app password

1. Go to myaccount.google.com → Security
2. Enable 2-Step Verification
3. Search for "App passwords"
4. Enter app name: VoiceBell → Create
5. Enter the 16-digit code in the app password field

Notifications available

• Payment complete / Payment cancelled / Payment method changed
• Password changed
• Daily sales Excel (sent automatically at your set time)
• Monthly / Quarterly / Annual summary Excel
• Other important security-related alerts

Go to Counter → Other Tasks → 5) Change Admin Password. If no password has been set yet, the setup screen will appear automatically on first entry.

If email notifications are set up

Go to Counter → Other Tasks → 5) Change Admin Password and press the Send temporary password by email button. A 6-digit temporary password (valid for 10 minutes) will be sent to your registered Gmail. Use it to authenticate and set a new password.

If email notifications are not set up

Delete your browser history from before the password was set to reset the password.

VoiceBell does not operate any cloud servers. All data is stored only on your server-integrated counter PC and is never sent to VoiceBell. However, if you have set up email notifications, sales data will be sent to the Gmail address you registered.

Sales data is automatically saved as Excel files in the orders folder on your desktop. Menu and store settings are securely stored in the server folder.

There is no need to worry. VoiceBell runs as a local server that only operates within your store's Wi-Fi network. It is simply not possible to access it from outside via the internet.

Voice ordering uses Google Speech Recognition. Your device sends a request to Google and receives a response — this is fundamentally different from hacking, where an outsider forces their way in uninvited.

The "connection not private" warning appears because there is no official security certificate, and has nothing to do with hacking.

We recommend using a dedicated PC for VoiceBell.

• 🏠 All data stays within your server-integrated counter PC. Nothing leaves your store.
• 📧 Email notifications are sent directly from your PC. No one else can see them in transit.
• 🙅 No customer personal information is collected. No names, contacts, or card numbers.
• 💳 VoiceBell subscription and pass payments are processed by Paddle. No card information is stored by VoiceBell.

Please check the following in order.

1. Make sure the counter PC is on. If not, double-click start_voicebell.bat to restart the server.
2. If the counter PC has entered sleep mode, move the mouse or press a key to wake it.
3. If Windows has automatically restarted for updates, simply run start_voicebell.bat again. We recommend scheduling automatic update restarts outside of business hours.
4. If the browser tab was closed, enter the following address in the browser address bar.

Completed payment data is not lost. It is already saved in the Excel files in the orders folder on your desktop.

Menu, store settings, and today's menu / recommended menu photos are stored in the server folder and will be retained after a restart.

However, orders currently in progress (before payment) will be lost if the counter browser is closed. If the browser remains open, the counter's order data will be preserved.

Run start_voicebell.bat again. Close the browser that opens automatically and continue using your existing counter browser.

Each terminal status is as follows.

• Counter — Data is preserved if the browser was not closed.
• Kitchen — Data is reset when the server restarts. Press the kitchen send button on the counter to resend the order. If the order was in cooking status before the server shut down, pressing Cooking on the kitchen screen will sync both sides back to cooking status.
• Kiosk — If the kiosk window was kept open, resending from the counter will update the kiosk in order. If the kiosk window was closed, that number will be deactivated. Please handle it from the counter directly.
