The passphrase was found in a secret directory on a network fileshare. Since I know the passphrase, I can test the person specificness of the door by recording me saying the passphrase and seeing how to door reacts.
Even with the correct passphrase, my voice would not open the door. I know we can do AI voice synthesis using available (even free) services online. We just need a clear sample of the target's voice.
You can download the audio book recording here:
wombleycube_the_enchanted_voyage.mp3
I took this recording and followed a guide on Youtube regarding AI voice synthesis. I used a platform called "Eleven Labs" which was either free or very cheap, and was able to create a cloned voice of Wombley Cube. I then ran the passphrase through the "Text to Speech" form at the ElevenLabs site.
The Text to Speech form output an mp3 file of the recording.
I used Audacity to convert this file to WAV format for the Space Island Door Access Speaker form.
You can download my synthesized passphrase here:
wombley_passphrase.wav
I used this file on the Space Island Door Access Speaker and it worked! It opened!
