〜から言うと・〜から言えば・〜から言ったら

About

The ～Xから言いうと pattern is used to express "based on X/judging from X/(speaking) in terms of X", where "X" is a noun.

言いう may appear in any of its conditional forms (言いうと・言いったら・言いえば) as well as in its て form.

E.g. 私わたしの経験けいけんから言うと、留学りゅうがくはした方ほうがいいです。 "Speaking in terms of my experience, you should study abroad."

E.g. 部長ぶちょうの性格せいかくから言って、無断むだんで休やすむことはないはずだ。きっと何なにかあったんだ。 "Based on the manager's personality, he's not likely to have taken off work without telling anyone. I'm sure something happened."

E.g. 実力じつりょくから言えば、スティーブさんが良いいと思おもいます。 "Speaking in terms of ability, I think Steve would be good."

～から言いうと cannot directly follow nouns that refer to people, such as 「先生せんせい」 or 「観光客かんこうきゃく」. Instead, it can follow noun phrases such as 「(noun)の立場たちば」 or 「(noun)の性格せいかく」.
