The subject of accents came up this weekend following an interesting discussion on world languages. The boy was interested in the idea that people could speak English in different ways (distinct pronunciations) and wanted to hear examples of this. YouTube was the ideal way to quickly explore a variety of regional accents, including Irish, Scottish, and Australian.
Since then, he can occasionally be overheard muttering phrases to himself in different accents as well as incorporating it into his play.
The British Library has an excellent resource for listening to UK-specific accents and dialects: Accents and Dialects of the UK.
