I haven’t been in a situation to really do any out loud speaking to people who’d know if my accent is wrong, but as far as things I do to try and get it right:
- I listen to the audio recordings on wanikani and try to, out loud, match the pitch patterns when I read them out loud.
- When I’m doing lessons on LingoDeer, I use the listen/speak lessons. I talk on top of the recorded voice and try to match the speed and pitch as much as possible until I’m doing as best as I can.
