zacksquest for AI, AKA 'Frank'
The AI is forever an important part of the game, and interacts constantly with Elias. In time, he gives it the nickname of 'Frank' and attempts to ease his loneliness of isolation by trying to have various bits of small-talk. Frank is well-equipped with useful information, but has a difficult time processing Elias' human social needs.
Frank sounds similar to your typical Alexa/Google voice service. 'He' is always pleasant and chipper sounding, even when informing the player that they are dying of some unknown toxin or a massive, bleeding wound.
As for Frank's overall voice and tone, I'd like to leave much of this to the person voicing him. It just needs to sound like an AI (not robotic, but still clearly lacking human emotion). Other than that, I'm all about artistic liberty.
Elias: "Alright, let's see if this still works. Computer?"
AI: "Greetings, Elias Frost. You are unauthorized to access the cryogenic containment chamber."
Elias: "Are there any other survivors?"
AI: "Scanning... no other crew members detected. Elias Frost rank upgraded to Acting Commander. Congratulations on your promotion."Elias: "Computer, are you getting this?"
AI: "It appears to be ruins constructed from local natural resources."
AI: "I am detecting nearby lifeforms."Elias: "Y'know what I could go for right now, Frank? A friggin' hot dog. With all the works. One of those cheap convenience store ones."
AI: "Consuming hotdogs would increase your potential for flatulence, which could alert nearby enemies. A diet low in sodium is advised."
