Voice translation for your calls

Your voice.Beyond borders.

Listen in your language and let your words reach the other person in theirs. Vocalia keeps both directions of the conversation separate, from your microphone to your headphones.

Illustrative example
You listen

Original voice: Hola, ¿empezamos?

Translation: Hi, shall we begin?

You reply

Original voice: Yes, I’m ready.

Translation: Sí, estoy listo.

Two languages. One conversation.

Speak, listen, understand

Another language should not stop the conversation.

Vocalia connects voice translation to your call setup. One channel translates what you hear; the other translates what you say. Choose your languages and devices, then stay in control of the session.

Two independent directions

Hear the translation through your headphones and send your microphone’s translation to the call, with separate language and device settings.

You stay in control

Choose inputs and outputs, adjust volumes, and use the controls to start, pause or stop each channel.

One account, your minutes

Sign in through the app, check your balance and buy available packages. One minute covers both channels active during the same period.

From installation to conversation

Three steps to get started.

Vocalia works with your audio devices and a calling app that lets you choose its microphone and audio output.

  1. Prepare your computer

    Install Vocalia for your operating system and, separately, VB-CABLE A+B from the official VB-Audio website. Connect your headphones.

  2. Choose languages and devices

    Sign in to an account with available minutes. Set up the listening and microphone channels, each with its own target language.

  3. Connect your call

    Select cables A and B in your calling app, check the connections in Vocalia’s setup guide and start the channels you need.

Bring Vocalia to your computer

Ready to talk?

Choose an available version for your operating system. Install VB-CABLE A+B separately to connect Vocalia to your call.

You need a Vocalia account with available minutes. Purchasable packages and prices are shown in the app.

The connection to your call

Two virtual cables. Two clear directions.

VB-CABLE A+B creates the virtual audio devices that connect Vocalia to your calling app. Cable A brings the call’s audio into Vocalia; cable B sends your translated speech to the call.

Windows setup
  1. Choose VB-CABLE A+B for Windows on the official website and obtain your personal download through the VB-Audio webshop.
  2. Extract the ZIP archive and run the A+B installer as administrator, following the manufacturer’s instructions.
  3. Restart when requested. Open Vocalia and check that CABLE-A and CABLE-B appear among both inputs and outputs.
  4. In your calling app, select CABLE-A Input as the speaker and CABLE-B Output as the microphone. Set up Vocalia’s two channels using the table below.
macOS setup
  1. Choose VB-CABLE A+B for macOS on the official website and obtain your personal download through the VB-Audio webshop.
  2. Open the downloaded package and follow the manufacturer’s installer, approving the operations requested by macOS.
  3. Restart when requested. In System Settings → Privacy & Security → Microphone, allow Vocalia to access the microphone.
  4. In your calling app, select VB-Cable A as the output and VB-Cable B as the input. In Vocalia, select the devices for both channels and your headphones.

Before you begin

The essentials, answered.

Can I use it with my calling app?

The connection uses virtual audio devices. Your calling app must let you choose its microphone and audio output. Configure the two cables and check the audio routing before use.

Are A+B cables included?

No. Obtain and install VB-CABLE A+B separately from VB-Audio. There are different packages for Windows and macOS; choose the one for your system and follow the manufacturer’s instructions.

Do I need to enter a Gemini key?

No. Sign in with your Vocalia account: the service manages the key and issues temporary authorization. The app sends audio directly to Google Gemini for translation.

Do two channels use twice as many minutes?

One minute covers both channels active during the same period. Usage follows authorized translation periods, rather than speaking time alone. End the session completely when you have finished; pausing the input does not close it.

Why are headphones recommended?

When translated speech plays through speakers, the microphone can pick it up and translate it again. Headphones help reduce this feedback, along with correctly selected inputs and outputs.
