Make iOs VoiceOver spell out abbreviated "W" as "Watt"

Question

I'm adding accessibility support to an app where one part of the app is a UIWebView with text information. The text contains abbreviated units such as W for watt, lm for lumen, etc...

The VoiceOver functionality does not by it self recognize the letter W as watt (of course it is hard) and it needs some help.

I know about the html tags and (http://www.w3schools.com/tags/tag_abbr.asp)

Eg.

15 <ABBR title='Watt'>W</ABBR><br>
15 <ACRONYM title='Watt'>W</ACRONYM><br>

Unfortunately they are not recognized by the VoiceOver system.

Does anybody know a way to make this work?

<span role="text" aria-label="Watt">W</span>;
