I rarely type anything by hand now. Instead I use Dragon Naturally Speaking and dictate everything straight into my computer.
When I first used Dragon I used the headset which came in the box with the software. Despite all my efforts, my work was full of mistakes. Eventually I realised it was the headset: it introduced errors into my dictation because the quality of the sound it transmitted was too poor for Dragon to interpret effectively. It was also uncomfortable, and so I couldn’t wear it for long without ending up with a headache and sore ears.
After a bit of research I discovered the Sennheiser ME3 headset. It was developed for use on-stage and so does not have an ear-piece, just a microphone: it’s very lightweight and comfortable (even if you wear glasses, like I do), and it’s very easy to adjust to fit. It has a plastic-coated, metal frame which rests on the top of your ears and goes around the back of your head, with a flexible arm for the microphone which allows you to position it correctly at the side of your mouth; and a soft Velcro strap which holds it close to the back of your head (only I prefer to use mine without it, as I have a notoriously large head).
Just by using the Sennheiser ME3 with Dragon and a USB sound-pod (I’ll cover sound-pods later in a separate piece) rather than using your computer’s inbuilt sound-card, you’ll get wonderful accuracy from Dragon.
The Sennheiser headset isn’t cheap: it costs around $150 US or £100 UK, but the improved productivity that it leads to means that it pays for itself within a few weeks if, like me, you depend on Dragon to work.
There are several suppliers: I’d suggest that you look first at KnowBrainer or eMicrophones if you’re in America, or IT Speaking if you’re buying in the UK. KnowBrainer has a good discussion forum too, where you can get lots of help with the program.
