I think you need to be clear on the difference between listening prediction tasks and speaking tasks. Prediction tasks are used for the receptive skills – listening and reading. They don’t always involve a lot of speaking and you shouldn’t try to make them into speaking tasks, especially at beginner level. Good prediction tasks can be used with any nationality; I don’t think it’s necessary to design them specifically for one group of students. The exception to this is when you are focussing on a language point that your students have difficulty with; in this case, listening might not be the aim of that stage of the lesson.
To encourage prediction, you can set the scene (for example by showing a picture or by describing the subject) and ask students to predict what they are going to hear. When they listen, they compare their predictions with the actual content. Another prediction task involves telling the students the topic of the listening text and asking them to say everything they know about a topic; they then listen to check whether what they know is correct.
