But these are difficult machine-learning problems to solve. The big issue is that accuracy needs to be near 100 per cent for these services to actually be useful.
For example, a recent DARPA speech-to-speech translation program called TransTac achieved 80 per cent accuracy, which was a fascinating and significant step, but still not enough for regular use.
There are also consumer apps like Vocre that offer services very similar to Skype Translate.
The difference here is that Microsoft is behind this service. Sure, the company may be struggling with its vision for tablets and other next-generation products, but it's still a major player, and Skype is pretty ubiquitous.
Whether Skype Translate is a hit right away or, more likely, it takes years to refine, Microsoft is being bold in bringing the technology to the mainstream now.
