speak with 和speak to 有什么区别？最好用中英文双语解释，谢谢！

speak with

speak to
v.
对...说话, 说到, 责备, 证明
Only one side speak

speak with

我可以跟Anderson先生或太太说话吗？

speak to
1. 提及
We haven't much time, please speak to the subject.
我们时间不多,请不要离开话题。
2. 找某人谈话
"Hello, may I speak to Mrs. Green? Just a moment. / Hold on."
你好，我找格林女士。 等一会儿。

与talk...to talk...with类似，with一般带有互动交流的意思，而to则着重指动作执行者有交流意愿。

speak with : 二者说话平等，共同谈论或商量
speak to：一方对另一方说，A主讲，B主听，而且B可有可无。

speak with指和什么人商量什么事情 talk with sb aboutsomething.
speak to指对什么人说什么 sb have sth want to tell sb.

speak with 和speak to 有什么区别在于speak with强调商量 是双方的而speak to强调一方对另一方说
