(CSS) Aural Style Sheets

Aural style sheets use a combination of speech synthesis and sound effects to make the user listen to information, instead of reading information.
Aural presentation can be used:
  • by blind people
  • to help users learning to read
  • to help users who have reading problems
  • for home entertainment
  • in the car
  • by print-impaired communities
The aural presentation converts the document to plain text and feed this to a screen reader (a program that reads all the characters on the screen).
An example of an Aural style sheet:
h1,h2,h3,h4
{
voice-family:male;
richness:80;
cue-before:url("beep.au")
}
The example above will make the speech synthesizer play a sound, then speak the headers in a very rich male voice.

Xiaomi Mi 11 Ultra review

  Introduction Now that the Pro moniker has gone mainstream, it's Ultra that has come to represent the cream of the crop, and the Xiaomi Mi 11 Ultra can wear that badge proudly. Limited to its home market last year, the ultimate Mi has gone global this time around, and we're happy to have it for review today. We're torn whether it's the camera system's physical appearance that is more striking or the hardware inside. A simply massive raised area on the back looks bolted on, almost after the fact, it's hard to miss, and it's a great conversation starter even if it's not everyone's cup of tea. But its size is warranted - the main camera packs the largest sensor used on a modern-day smartphone, and next to it - two more modules unmatched in their own fields, in one way or another. Oh, and yes, there's also a display here - because why not, but also because it can be useful. There's a lot more than 1.1 inches of ...
