I am an early 30s male with upper intermediate – advanced Japanese and I had some questions about the masculine voice. I do not use the common feminine words (かしら、statement〜なの、using my name in third person, etc.) and have been told I have very good standard/flat Japanese, which is good for both business meetings and casual conversation. I recently got told by a close bilingual friend (Japanese native) that my English way of talking sounds very masculine/ dominant (in a good way) but my Japanese voice sounds ‘too normal’. It’s not bad, but it doesn’t sound as masculine as it does in English.
I have searched for advice on this on the site but all of the results are saying things like :
verb stem+てえ (e.g バスケやりてー）
Which is very young or crude in my experience.
Or things like:
〜〜かい / 〜〜だい （e.g. そうかい？）
Which are very old and also weird for me to use (unless using it sarcastically).
There are many examples like this on the site but they aren't that common for 30s men to say, in my opinion. Maybe I am wrong.
I am trying to figure what a middle-aged Japanese man would do to sound masculine in everyday conversation.
My friend didn’t understand what makes someone sound masculine in Japanese, so she couldn’t give advice, but she could notice the difference. Do you have any advice for sounding more masculine/ dominant in Japanese? Are there any tips that you have noticed around word choice or speaking cadence?
