Hi Dede Generally speaking, there is not a big difference between the two verbs, both mean 'to say something'. Nevertheless, we use 'to speak' in more formal situations: E.g.: 'I need to speak to you' because you don't know the person very well, because you want to speak to your boss or because you want to speak about a serious or important topic. E.g.: 'I need to talk to you' because you want to talk to your friend or you want to say something informal. Note that, if we refer to a language, we always use the verb 'to speak', e.g.: I speak English, Spanish and French. Also, we speak on the phone instead of we talk on the phone. Kind regards Karen

We usually use speak for more formal presentations and lectures, and talk for more informal ones: Dr Graham Foster will speak about the history of the region. Kyle is going to talk us through the benefits of the software and then Liz will talk about the marketing plan.
