* Sọ̀ o, sọ̀ ni (pronounced "soh oh, soh ni"): This is a combination of the two previous phrases and is even more emphatic, urging someone to speak.
Formal:
* Jọ̀wọ́, sọ̀ (pronounced "joh woh, soh"): This is the most polite way to say "Do speak" and is used when addressing someone older or in a position of authority. It literally means "Please, speak."
* Jọ̀wọ́, sọ̀ mi (pronounced "joh woh, soh mi"): This means "Please, tell me." It is a more direct way of asking someone to speak and can be used in situations where you need more information.
Note: In Yoruba, word order is flexible, so you can say "sọ̀ o" or "o sọ̀" and they both mean the same thing.
The best way to say "Do speak" in Yoruba depends on the context and your relationship with the person you are speaking to.
