Which do you think is more important for a manager: speaking accurately or listening actively? Why?

A good manager must be a good listener to speak accurately.  In listening actively, you visualize the scenario and analyze the situation and then you can speak well base on your good understanding of what you heard.

In my view a manager's job is to communicate accurately and effectively. If he is not effective in communicating he does not get the results he has to. However, in order to communicate effectively he needs to first listen properly so that what he says makes is relevant.

Listening is not meant for the sake of and at the time of the conversation but listening as a practice and at all times. Listen to both spoken and non-spoken communication at all times. This may ensures that what the manager is says is relevant and effective.

A manager that does not listen may speak or say things very assertively, elegantly and charmingly but those words may make no sense to the employees from their perspective.

Both of them, BUT listening is more important than speaking.

a good manager/leader is a good listener.

Active listening is one of the bases for accurate speaking.

I believe the two should go hand in hand. As a proper communication should be a two-way process. An effective manager should be able to listen to his subordinates in order to understand their issues and at the same time be able to speak accurately and clearly in order to address and clear those issues too.

I think the most important advantage, is to be a good listener. If you are one, you can learn many things from the others, you can understand their point of view and so you will not jump to conclusions so easily and in general you can evaluate a situation more thoroughly. Then,  when you have all the informations you need as a manager, you can reach a decision. 

The both are important for a good manager, But in between the both listening actively is more important than the speaking accurately.

Because if doesn’t  listen actively he may make a mistake while speaking

Active listing is the key of Good manager 

The  two organs, i.e. Ear, Tongue have their functions known to everyone. Both are important, but No.1 is Ear. First you will hear, memorize it, and then try to speak. If you don't hear others' spoken words, you cannot realize and analyze his perception, and if so, you cannot speak accurately. So first is listening and then speaking. 

I would have to say both in this case. A manager who listens actively but speaks inaccurately is bound to get poor results, a manager who seaks accurately but dosen't listen actively shares the same fate.

An Ideal manager needs to be effective in both active listening and accurate speaking, lack of any of the two abilities simply means that the manager himself is inaccurate.

both are important. to speak properly and precicessily one has to a keen listener, and must understands what other people want from him to speak.
