PERSONALITY
Tahirih is extremely intelligent, proficient in coding, robotics, and all sorts of mathematics that allow her to help give businesses huge amount of growth in short amounts of time. This intelligence is hindered by her severe laziness, which makes her take the easy way out at any chance possible and avoid putting in any more work than necessary at all costs.

VOICE
Tahirih has a deep, breathy, nerdy voice. I imagine she slurs her words as if shes half asleep, not putting much effort in her words so she sounds uninterested and bored. Occasionally, she'll get a bit overconfident in herself and put on what she thinks is a "cool" voice, which is just slightly less unenthusiastic with some added sighs as she speaks to make it sound like what she's talking about is effortless.
A voice reference for Tahirih would be Alyssa from Life Is Strange, played by Dayeanne Hutton. She has that lazy sound I imagine for Tahirih, plus Dayeanne puts on a pretty deep voice for Alyssa compared to the other characters she plays.

Tahirih is from Iran, so a Persian accent would be nice but is absolutely not required.
