Did the chief help Cortana active the halo ring?

During the level where chief arrives at Genesis, he activates multiple consoles which were activated using the “olly olly oxen free” command.

Looking back at the legendary ending where Cortana activates a halo ring I can assume that the Halo ring was voice activated. 343 Guilty spark may have not had anything to do with Halo 5 or even 6.

When Cortana hummed before the halo ring activaed (legendary ending) she hummed olly olly oxen free. https://www.youtube.com/watch?v=2Nj5C-0WGRI (Subscribe to this man no copyright intended). The music which is compared with her hum is indeed olly olly oxen free. Could master chief activating those consoles have let Cortana voice activate the halo ring with olly olly oxen free?

She seems able to activate anything Forerunner just fine with the power the Domain grants her, I don’t think she needed Chief. I’m unsure she was humming Oly Oly Oxen Free, she seemed to be humming the song in the intro cutscene with Halsey (unless that incorporates the tune).

I don’t think the tune activated the Forerunner consoles either. Cortana just played it at them to let Blue Team know that it was all clear and that the presence was “friendly”. She wasn’t humming that tune on the Halo either, but the piano melody from the first cutscene. If she was preparing the ring to fire, she probably just retrieved the index digitally at some point, like she did on Alpha Halo.
