A world where there are no more language barriers might not be too far away - online, at least.

Skype has now released the beta version of its live translation tool, allowing people to speak to others in another language - even if they don't know what they're saying.

The tool translates speech instantly, providing both text and spoken translations.

Washington-based Microsoft has released a preview of Skype Translator (shown). It lets people of different languages talk to each other on video calls. The software translates one language into text and speech of another. For now only Spanish and English are available - and you need to have a Windows 8.1 device

You can sign up for the beta version of Skype Translator now on their website.

For now the public version is only able to translate between English and Spanish - and you need a Windows 8.1 device to use it.

But it will eventually have more than 40 languages available letting people of many countries speak to one another with ease.

There's no news yet, though, on when the full version will be available. 

'Skype is now removing another barrier to make it possible for people to communicate irrespective of what language they speak,' Microsoft's Gurdeep Pall wrote in a blog post.

'Skype Translator relies on machine learning, which means that the more the technology is used, the smarter it gets.'

'We are starting with English and Spanish, and as more people use the Skype Translator preview with these languages, the quality will continually improve.'

The service works by translating your speech as you talk.

It provides a text version of your speech for the person on the other end of the line, and also reads out what it thinks the translation is.

To turn it on, you simply need to select the translation setting before making a call to someone. 

Initial reports from the beta version say it is good, although not perfect.

'For Skype Translator to work properly, there is a little mental conditioning involved,' reported Gizmodo.

'For one, you must speak slowly. Skype Translator's speech recognition is good, and plenty fast, but that accuracy decreases as you speed up in words per minute.

'"Hey, how is it going?" can change to "Hey is going?" pretty quickly.'

It's also recommended that the speaker doesn't 'um' and 'ah' too much, as this can confuse the translation tool.

Microsoft first unveiled the technology two years ago. At the time, though, it was deemed too inaccurate to release to the general public.

But a breakthrough by the Skype and Microsoft Translator teams in neural network-based speech recognition reduced errors in speech recognition by more than 30 per cent.

Microsoft says Skype has more than 300 million users, while at least 2 billion minutes of conversation are spoken every day.

Skype can be used across a variety of devices including computers, smartphones, tablets and TVs.

It allows users to either voice-call or video-call friends and family anywhere in the world without the large costs of regular phone tariffs.

Skype Translator is a spin-off of the technology behind Microsoft's Siri clone called Cortana, the personal voice assistant on Windows Phones.
