Code parsing:

WebClient provides a public method for receiving data from resources. We can download data from a remote url (Access Service ).

JsonConvert. DeserializeObject deserializes string into a json object

Voice is a playback icon. The audio file address of a word is stored in the Tag attribute of voice.

Note:

In the json returned by a word query, Voice represents the name of the word speech file. The url for accessing the voice file is http://www.boapi.net/basicdata/voice/single-Word file name.

For example, to query "voice": "good.wav" in the json returned by good words, the url of good words is the http://www.boapi.net/basicdata/voice/good.wav
