Smart phones are kind of figures which provides the language some new concepts. Many of us must have seen the term ‘podcast’ on their phones or computers, but untill now I don’t think any of us know what it really means.
In wiki definition it says a podcast (or netcast) is a digital medium consisting of an episodic series of audio, video, PDF, or ePub files subscribed to and downloaded through web syndication or streamed online to a computer or mobile device. The word is a neologism and portmanteau derived from “broadcast” and “pod” from the success of the iPod, as audio podcasts are often listened to on portable media players. To cut it short, it’s a kind of tool which help us to listen any kind of material through downloading or syncronization in whatever language, topic and context we want.
In communicative approach, the main point is that language is learned through listening. If we say English has more main skills, listening is one of the most important ones. No one can promise you to talk like a native speaker of the language that you have been studying, but you can achieve to understand every single language item in whatever accent they talk.
To sum up, just like listening to music with your headphones while travelling by a bus, you can do yourself a favor in terms of developing your listening skills and knowledge background by using podcasts.
