One of the AnkiDroid maintainers here. This is entirely my personal opinion and not representative of a general consensus.
I am strongly opposed to this for ethical reasons. Distracting drivers will kill people. This functionality would also increase the risk of death for non-users of the software.
Drivers distracted by talk is already a thing through radio, phone and physical company. A purely voice-driven anki should not entail more risk than a conference call.
That makes sense and I respect your opinion, but I don’t share the concern.
My country, Spain, has reached just 29 deaths per million inhabitants and year due to road accidents by focusing on the big risk factors, such as dui, speeding, lack of seatbelt use, overall disregard for traffic rules, texting and handling phones, bad infrastructure status, etc. and I don’t think talking while driving is a big part of the remaining risk factors that contribute to deaths.
That last part is just my opinion though; I’m just saying the problem is serious but imo lies elsewhere.
