I would like to start recognizing tones, accents and stresses in languages I already know. Are there efficient ways to do this?
For a little more background : I have recently become aware of the phenomenon of pitch accents (here and here, although the articles are far too advanced for me) after starting to learn Mandarin tones.
Interestingly, Japanese (where I can follow and participate in simple conversations) seems to have a pitch accent. English and German, though mostly stress-based from what I can read, also appear to use pitch changes in some cases. I'm hoping to train my brain to recognize those accents in languages I know and use, in hopes to be able to learn them better, and eventually to improve my speech.
