This error indicates that the sounddevice Python library cannot find the required PortAudio system library, which is necessary for the real-time speech-to-text feature. Since you are using Linux, you need to install the PortAudio development package.

To resolve this, please install portaudio using your system's package manager. The exact command depends on your distribution:

  • For Debian/Ubuntu-based systems:

    sudo apt update && sudo apt install portaudio19-dev

  • For Fedora/RHEL-based systems:

    sudo dnf install portaudio-devel

  • For Arch Linux:

    sudo pacman -S portaudio
  • For Slackware (your system):
    You may need to find and install the PortAudio package from your distribution's repositories or compile it from source. A common source is http://www.portaudio.com/download.html.

After installing the system library, restart the pyVideoTrans application. The real-time speech-to-text feature should then work.

If the issue persists after installation, ensure your Python virtual environment is reactivated.
