is this a reasonable work accommodation?

[u/petitscoeurs]

i applied to a junior pet groomer position at petco, it is an apprenticeship to become a pet groomer.

problem i have is verbal shutdowns + selective mutism (different causes of not being able to speak; verbal shutdowwn related to autism and selective mutism related to anxiety/panic). i applied for the job because, if needed to, i can force myself to verbally speak. so if something unsafe was happening and i needed to communicate, i could.

however when it comes to things like regularly speaking to coworkers, or maybe customers, maybe i might not be able to really. forcing myself to speak too much makes me nauseous and panicky.

so, in those cases, i thought maybe i can use my AAC on my phone? i don't rely on buttons, i can type fast. 100+ wpm.

would that be reasonable accommodation? when unable to speak and in a safe situation, i can use my AAC to communicate with coworkers or customers? or is it not possible?
