Speaking (noun) and Improve in Japanese.

[Huankun]

I'm not sure if this question has been asked, but how do you say "Speaking (noun)" in Japanese?
And what about "Improve" in Japanese?
I'm having a hard time to search for these 2 word, so please help me. Thanks in advance!

You mean the language skill? You can use the katakana word スピーキング or 会話力（かいわりょく）. For improve, maybe 伸ばす（のばす） is best, but you can use lots of words like 上達させる・上げる・高める・強化する・アップさせる・向上させる・鍛える・磨く etc. A 例文 might be「スピーキングを伸ばしたいです」.

"Speaking " is "kaiwa" in Japanese.
"Improve" is "joutatsu" or "jotatsu" in Japanese.
