Four in five (80 percent) Brits believe the quality of their written English skills has suffered thanks to the rise in gadgets such as smartphones with predictive text, says Livescribe.
Research by the company which created the Pulse Smartpen - a pen that records and links audio to the phrases you write - revealed that 63 percent of mobile phone owners use their handset everyday.
Furthermore, more than a third (34 percent) admitted they had mistakenly used text speak such as 'pls' or '2moro' in handwritten situation.
Livescribe also said 19 percent of Brits feel disconnected when they're not in possession of gadgets such as smartphones and laptops, while 29 percent say they feel 'powerless'.
"This survey points to a worrying precedent that suggests standards in writing and spelling in British adults are deteriorating in later life due to an over-reliance on technology programmes such as predictive texting," said Dr Bernard Lamb, president of the Queen's English Society.
"It implies that in the absence of these devices people are going to struggle to remember how to spell."
