How to say "lecturer" in Japanese

• 講師こうしJLPT N2approx.Common
  nounCovers lecturer in the teaching sense: a person engaged to give lectures or instruction, as at a university, school, or seminar. The word you want when English 'lecturer' means an instructor.
  講師こうしは本題ほんだいから脱線だっせんしてしまった。↗

  The speaker wandered away from the subject.
• 弁士べんしCommon
  nounPoints to the orator side of 'lecturer': a person skilled in public speaking, a rhetorician. For a lecturer who teaches or gives instruction, it is seldom the word you want—use 講師.
  彼かれらは、弁士べんしを大おおいにほめた。↗

  They paid a high compliment to the speaker.

Choose 講師 for a lecturer who teaches—someone engaged to give lectures or instruction—since 弁士 centers on the orator and rhetorician sense, a skilled public speaker, and is seldom the word for a teaching lecturer.
