Translation:The teacher does not speak English.
MoozieGoozie's sentence adds the character hui, which changes the meaning of the sentence from Teacher does not speak English, to Teacher cannot speak English (ie. does not have the ability). The first one could mean simply that the teacher is choosing not to speak English, say in the classroom to improve language learning. Chinese people use the term Teacher as a form of address for a teacher, just like Professor and Doctor. So perfectly normal in Chinese to say Teacher does not speak English. The sentence can also mean The teacher does not speak English, depending on context.
