this one has the best selection of dog breeds out of all of the DS games, in my opinion. speaking about all of the games, though: the microphone's already a bit tricky on original hardware and becomes more of an issue if you're emulating, but using melonDS and speaking closely to your microphone helps mitigate that. i have no idea how an accent or impediment would affect things though, i'm from one of the most mild-sounding places in the united states with no speech issues and had no problems with it recognizing what i was saying.

for what it is, it does its job well and i have zero complaints. if you don't like this game, i think it's an issue with you not liking the "virtual pet" genre as a whole. it doesn't help if you're playing this for the first time as an adult who never had any childhood interest in it.
