What is on the QDub screen?
The main screen has four areas:
- The tab row — switches between Text to Speech, Speech to Speech and OCR.
- The language bar — your source language on the left, the target language on the right, with a swap control between them to reverse the direction.
- The conversation area — where the transcript appears as you speak.
- The microphone control — at the bottom of the screen, with the Smart-Mic toggle beneath it.
The header carries a saved-items icon, a split-screen icon and a menu button.
How to Set Your Languages?
Languages are selected before you start, from the language bar at the top of the screen.
- 01Source Language
Tap the language on the left and choose the language you will speak.
- 02Target Language
Tap the language on the right and choose the language you want to translate into.
- 03Reverse Direction
Use the swap control between them to reverse the direction at any time.
You can change either language during a conversation without restarting the session.
What is Smart-Mic?
Smart-Mic is the toggle below the microphone button. It controls how QDub listens. Smart-Mic on gives continuous listening, where QDub picks up speech automatically, and Smart-Mic off gives push-to-talk, where you hold or tap the microphone to speak. Both modes are available.
What audio preferences can I set?
Audio preference controls the voice QDub uses when it speaks a translation aloud. You can choose between a male and a female voice.
To change your voice preference: (flowchart)
01 Open Settings from the menu in the QDub header.
02 Select the audio preference option.
03 Choose Male or Female.
Your selection applies to spoken output in both Speech to Speech and Text to Speech, and can be changed at any time.
What is stored in my profile?
Your profile holds your name and your audio preferences. Of these, only the audio preferences can be changed after your account is created. Your name, email address and phone number are set at sign-up and cannot be edited in the app.
What can I do from Settings?
Settings is where you manage your account and plan. From there you can:
- Buy the Pro plan
- Rate the app
- Set your audio preference
- Read the Terms of Use
- Read the Privacy Policy
- Deactivate your account
Does QDub work offline?
No. QDub needs an active internet connection. Translation will not run without one.
If your connection drops mid-conversation you will notice a delay, and voice output pauses until the connection is stable again.
Can I use Bluetooth headphones or earbuds?
Yes. If your phone is already routing audio to a Bluetooth device, QDub uses it. The app itself does not have an audio device selector, so switch devices from your phone STS rather than inside QDub.
