Hear it and see it
The tool combines two ways of learning a pronunciation. First, the phonetic spelling shows the word's sounds using standard symbols, which is useful for reading pronunciation guides. Second, where the dictionary has recordings, you get playable audio so you can hear the word spoken and copy it exactly.
When a word has multiple accepted pronunciations — for example across British and American English — the tool lists each one it finds, so you can choose the variant that suits you.
