On the other hand, DECT technology offers clear advantages for use with speech recognition software.

When I tested the Plantronics Voyager, a Bluetooth earpiece that Nuance used to provide with Dragon Dictate (Nuance now offers the Plantronics Calisto), the sound quality was poor and there was interference coming into my ear. The frequency range of Bluetooth is somewhat limited, and Bluetooth earpieces are very short and their booms don’t reach anywhere near the corner of your mouth. Because of the way Bluetooth works and the way Bluetooth earpieces are designed, they don’t offer good accuracy with speech recognition software. The former is commonly used for those tiny earpieces that people use with cell phones. Plantronics Savi 440As I mentioned previously, there are two types of wireless technology: Bluetooth and DECT.

After all, one of the reasons to use dictation software is so you don’t have to keep your hands on your keyboard. In addition, some people like to move around while they dictate I like to stand up, pace in my office, and have nothing forcing me to remain seated at my desk. That long, sinuous cable, that gets tangled whenever you reach for something at the far corner of your desk or knocks over your coffee cup, can be an annoyance. While wired headsets offer excellent accuracy, they keep you tied to your computer. However, while the accuracy is very good, there is a slight hiss in the earpiece, and a slight echo as my voice seems to come through the earpiece. It also contains an in-line control device, allowing you to change the volume or mute the microphone whenever you want. This microphone is very light, and, in spite of of the fact that you have to wear it over your ear, is fairly comfortable. You can either use both of them if you want stereo sound, or just the one with the microphone boom if you’re doing basic dictation or VoIP calls. The $100 Plantronics Blackwire 435 is an interesting wired USB headset, with two separate earpieces that are connected together by wires, but that you can only wear using over–the–ear adapters. If you plan to do any serious dictation, you should look for headsets that are specifically designed for speech recognition. While Dragon Dictate may offer good accuracy with a cheap headset, you’ll be spending a lot of time correcting mistakes, and it would probably be more efficient to type rather than dictate. For this reason, headsets designed for speech recognition include noise canceling features that eliminate noises around you-be they the voices of your coworkers, the sounds of cars coming from an open window, or phones ringing in nearby offices.įor this reason, you cannot use just any headset for speech recognition.
This sound quality depends on the ambient noise in the environment in which you dictate. UmeVoice theBoom CSpeech recognition software is very sensitive to the quality of the voice the microphone pipes into your computer.
On the other hand, headsets can be annoying to wear they mess up your hair, and if you wear glasses, headsets press them against your head, and the wires that tether you to your computer can prevent you from moving around.

On the plus side, headsets offer very good accuracy-speech recognition software will get more words right because the microphone connected to a headset is generally in a good position. However, the type of headset you use to chat over the Internet is not at all what you need for speech recognition software.įirst, consider the pros and cons of using a headset. You may be using a headset now to talk to friends or family via iChat or Skype, so using one for dictation won’t seem very different. Headsets are the most common type of microphone that people use to talk to a computer. Wired headsets: Basic tool for talking to a computer Good headsets may cost more than the actual speech recognition software you use, but if you plan to spend a lot of time dictating, the amount of time you save using speech recognition software ensures that this investment will pay for itself very quickly. (Technically, you can use your Mac’s internal microphone, or the one in your monitor if you use an Apple display, but this won’t give you the best results with speech recognition software.) Finally, you can use a desktop microphone, which allows you to work without wires or without wearing the mic.
