Peter Travis, of Splendid Speaking, produces a weekly podcast for advanced level English Language students. Students contact him to sign up for an interview through Skype.
The interview will be student driven and the content will be determined by, for example, the particular exam they might be doing or a situation at work that they want to practise for such as an interview or meeting. The interviews are recorded using Powergramo and then posted as a podcast for other advanced learners to listen to.
Each podcast features an introduction to the skill being looked at, the interview itself and then feedback from Peter on the student’s performance.
The podcast is hosted at Podomatic: Splendid Speaking.
