How to Setup Real-Time Subtitles & Audio Translation for Zoom & Microsoft Teams

1. System Prerequisites

Before initiating real-time speech translation during live online meetings, ensure your workstation meets the following hardware and software requirements:

• OS: Windows 10 or Windows 11 (64-bit).
• RAM: 8 GB minimum (16 GB recommended for seamless multitasking during video calls).
• Audio Interface: Standard built-in soundcard supporting Windows Audio Session API (WASAPI).
• Storage: ~850 MB free disk space for local AI model files.

2. Installation & Language Pack Download

Download the latest standalone executable setup file from Voxxwire's official download page. Run Voxxwire-Setup.exe and follow the wizard.

Upon launching Voxxwire for the first time:

1. Select your Source Language (e.g. Japanese, German, Spanish) and Target Language (e.g. English).
2. Choose your preferred Whisper ASR model size (e.g. base or small).
3. Click Download Language Pack. The app will fetch the corresponding offline translation pair once. Subsequent launches require zero internet access.

3. Configuring Audio Devices (Mic & System Output)

Voxxwire uses dual-channel audio capture. Channel 1 captures your local microphone (your voice), while Channel 2 captures WASAPI system audio loopback (the remote speakers in Zoom or Teams).

# Device Selection Matrix
Local Microphone  --> Input Channel 1 (Your Speech)  --> Whisper ASR --> Translation
System Loopback   --> Input Channel 2 (Remote Speech) --> Whisper ASR --> Translation

In the Voxxwire main control panel:

• Set Microphone Input: Choose your default physical mic (e.g. Realtek High Definition Audio or USB Headset).
• Set System Audio Input: Select Default System Output (WASAPI Loopback).

4. Connecting Voxxwire to Zoom & Microsoft Teams

Because Voxxwire captures system audio at the OS driver layer, no Zoom app plugins or custom Teams permissions are required!

1. Start your meeting in Zoom, Microsoft Teams, or Google Meet as usual.
2. Position the Voxxwire window alongside or overlaying your meeting window.
3. Click Start Listening in Voxxwire.
4. As participants speak in the foreign language, real-time dual-line subtitles appear instantly on screen showing the original transcript and English translation side-by-side.

5. Troubleshooting Audio Loopback & Performance

If subtitles do not appear when remote participants speak:

• Verify that your headset or speakers are set as the Default Communications Device in Windows Sound Control Panel.
• Ensure WASAPI loopback isn't muted in Windows Volume Mixer.
• If using high-CPU video effects in Zoom, lower the Whisper model setting in Voxxwire from small to base or tiny to reduce processing load.
