Train journeys home could soon be a little less unpleasant if a prototype device unveiled at the Cebit electronics fair in Germany becomes a reality.
According to the BBC, work is well underway on a system that could allow people to talk silently on their mobile phones.
It works by capturing the electrical pulses generated by facial muscles as they form words and then converts those signals into synthesised speech.
It means that the person would be able to talk without making any audible sound at all and eventually the device may also be able to translate speech instantly into other languages.
Although still a long way from a marketable product, the inventors, and undoubtedly many commuters, are hoping that the technology will soon be incorporated into normal mobile phones.
