IBM unveils Speech Markup Language

A markup language that lets Web authors include interactive speech capability in Web pages has been unveiled by IBM today.

The company announced Speech Markup Language (SpeechML), which provides an open framework to add speech capabilities to Web-based applications.

SpeechML is based on Extensible Markup Language (XML), which is a specification for formatting data on Web pages. SpeechML will be considered by the World Wide Web Consortium (W3C) as the standard for speech markup language, according to a statement from IBM.

SpeechML is designed to let a Web site developer use "tags" to add interactive speech capability to his or her Web site without being an expert in speech technology, the statement said. Tags are the way the developer marks certain Web site content as content that is to be spoken by an application, such as reading a menu to a Web site visitor, IBM said.

SpeechML is used in conjunction with a conversational browser, which enables the markup language by interpreting and translating it, IBM said. The conversational browser is technology designed to interpret and translate streams of markup language data coming from many sources, it said. For example, in the middle of the online purchase of an airplane ticket, a user can suspend the purchase and communicate with a banking application on a different server to check an account balance, it said.

SpeechML is available for free download at http://www.alphaWorks.ibm.com/. The download includes guidelines for SpeechML, a conversational browser and a set of demos, IBM said.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
