HOW TO RECOGNIZE SOUND FROM APPLICATIONS AND TABS (via VB-CABLE virtual cable)

Web Speech API recognizes audio from a microphone. To recognize sound from a call, video or tab, you need to “wrap” it into a virtual microphone using a free program for a virtual cable like VB-CABLE (or similar). This is done once:

1. Download and install VB-CABLE (VB-Audio Virtual Cable). After installation, virtual devices “CABLE Input” (speaker) and “CABLE Output” (microphone) will appear in the system. Restart your computer if the installer asks.

2. Enable listening to the VB-CABLE microphone. Open "Sound Options" → "Sound Control Panel" → "Recording" tab → select "CABLE Output" → "Properties" → "Listen" tab → check "Listen from this device" and select your actual headphones/speakers. This way you will hear the sound that goes into the virtual cable.

3. Select the VB-CABLE virtual speaker in the extension. Open the side panel of the extension, expand the "Speaker-Microphone" block and select "CABLE Input (VB-Audio Virtual Cable)" in the list of output devices. The extension will route the current tab's audio into a virtual cable.

4. Click "Start" and allow access to the microphone. The extension will begin to recognize the sound coming through the virtual cable and display text in the panel.

Bottom line: tab sound → virtual speaker VB-CABLE → virtual microphone → speech recognition → text in the panel. At the same time, you continue to hear the sound thanks to the enabled listening (from step 2).

In such services, selecting an audio output device through an extension may not work - these applications and sites themselves control which speaker the audio is output to. In this case, select the virtual speaker "CABLE Input (VB-Audio Virtual Cable)" manually in the settings of the application or website itself (section "Sound" / "Speaker"). After this, the extension continues to work correctly and recognizes speech - it is only necessary that the sound be output to the VB-CABLE virtual speaker, and how it is directed there (through the extension or through the application/website itself) does not matter.
