The woman who my mother is speaking is my English teacher怎么改错

The woman who my mother speaking to is my English teacher

speak 当及物动词时是表达的意思

The woman whom my mother is speaking with is my English teacher

因为my mother is speaking (with) 谁. the woman指人故用who 或whom.因为我妈妈和(这个女人)说话.这个女人作my mother的宾语故用whom

The woman who my mother is speaking "with" is my English teacher

应该是：把who改成whom的吧！
