Guest Post :: Wireless Microphones for Use with MacSpeech Dictate Legal

Posted on November 16, 2009 by Ben Stevens Posted in Guest Posts, Hardware, Product Reviews 5 Comments

The following Guest Post was written by one of my readers, Michael Yurkanin, and it reviews several wireless microphones to address their use with MacSpeech Dictate Legal:

I. Introduction

There have been many articles written about the latest version of dictation software by MacSpeech, MacSpeech Dictate Legal. To use the software requires a microphone. The majority of the microphones recommended by MacSpeech are wired and plug directly into a USB port. MacSpeech, however, now endorses two wireless microphones which they sell on their website, the Samson AirLine 77 Wireless USB and the Revolabs xTag USB Wireless Microphone.

These microphones eliminate another set of wires crossing your desk and are also convenient if you have to step away for a moment since you do not have to remove a headset. On the negative side, both of these microphones are quite expensive compared to a wired microphone. Aside from the cost consideration, the two microphones are significantly different from each other. This review will provide you with information to consider before purchasing so that you will choose the wireless microphone best suited for you.

(MacSpeech recently added the Plantronics Calisto Headset + Bluetooth USB Adaptor which is not included in this review.  This headset was originally designed by Plantronics for use with the Plantronics Calisto Pro Home Office Phone which is sold online and at office supply stores. I have used the Home Office Phone Bluetooth headset and it works well as a phone. The modified Calisto Headset for dictation will be reviewed in a forthcoming article. One item to note is that the Plantronics Calisto Headset uses Bluetooth technology and will have a much smaller range than the other two units.)


 II. Samson AirLine 77 Wireless USB

The first microphone for review is the Samson AirLine 77 Wireless USB. MacSpeech sells the microphone for $349.00 through their online store. The microphone is also sold by other online retailers for slightly less. The Samson wireless microphone is designed as a headset that wraps around the back of the head and sits on both ears. The headset transmits over UHF frequencies to a receiver that is ultimately connected to the computer through a USB sound pod. According to the people at MacSpeech, using UHF frequencies gives the Samson a range up to 300 feet, significantly more than the XTag. The headset itself is very stable, but some find it bulky and uncomfortable.

Strangely enough, this wireless microphone was not made for dictation. This unit was designed for recording artists, performers, and audio professionals. An aerobics instructor using the headset is pictured on the box. (You can find more information about Samson products their website). The AirLine 77 has been adapted for dictation using a USB sound pod that connects between the FM receiver and a USB port on your computer. For general information about USB sound pods see this link, which also discusses the various brands of sound pods available. The MacSpeech store website does not indicate the brand of USB sound pod they use.

The AirLine 77 package comes with the wireless headset, CR 77 Receiver, ¼” x ¼” phone plug with 3.5mm adapter and an AC adapter. The headset requires a AAA battery, but a battery was not included in my package. When ordering from other than MacSpeech, it is important to ensure that you are ordering the AirLine 77 Wireless USB, which should include the USB sound pod. In one instance, I ordered the AirLine 77 Wireless USB from an online retailer and paid for that version, but the seller failed to include the USB sound pod. After a series of emails, I finally received the USB sound pod a week later. Without the USB sound pod, the headset and receiver are of no use. As to setup, the AirLine 77 is a bit more difficult than the XTag, but these instructions will prove helpful. (Note: clicking on this link will cause the instructions to download as a Microsoft Word file).

III. Revolabs xTag USB Wireless Microphone

The other microphone certified by MacSpeech to use with MacDictate is the Revolabs xTag USB Wireless Microphone. This unit is available from MacSpeech for $249.00 and is the less expensive of the two. It ships with a lapel microphone, lanyard for the microphone, charging base, USB cable for the charging base and an earphone for listening to playback. Setup is easy. You plug the base into the USB port, place the microphone into the base and wait for it to charge. Before the first use Revolabs recommends charging the microphone for eight hours.

Revolabs designed the xTag specifically for use by professionals for dictation. The unit is easy to operate and looks right in place sitting on a desk. The microphone is meant to be attached to a shirt or can be worn around the neck on a lanyard. Revolabs says that the microphone has a range of 65 feet from the base. A demonstration of how to use the xTag is available here. More detailed information about the xTag is available at the manufacturer’s website.

Overall, the xTag is much simpler to set up and use. The base unit is small and compact. On the other hand, the AirLine 77 contains the UHF receiver, which most people will not want sitting out in the open, and the separate USB sound pod. In addition, the UHF receiver setup is more difficult and will require a little time to fine tune various settings for optimal performance.

One of the most important considerations between these two microphones is accuracy. The AirLine 77 is more accurate. In fact, one seller I came across stated that the microphone’s accuracy matches that of a corded microphone. My experience has been similar. The AirLine 77 is also more accurate in situations with significant background noise. The xTag, on the other hand, is slightly less accurate. This results from the distance between the mouth and the microphone itself. The accuracy of the xTag drops when used in noisier environments since the added gain necessary to pick up the voice also causes other noises to enter the signal.

IV. Conclusion

In conclusion, voice recognition depends on many factors. These include quality of a persons voice, pronunciation and pacing. In addition, one must consider ambient noise and any electronic noise. Electronic noise may arise if the microphone base is plugged into a powered USB hub. If this problem occurs it can be alleviated by plugging the base unit directly into a USB port on the computer itself. Finally, it is important for the user to correctly position the microphone. This factor is more important when using the xTag. In general, the AirLine 77 is best suited for people with quiet voices or those working in noisy environments. The xTag will work best for people with louder voices, better diction and quiet environments.

    I’ve tried several bluetooth mikes in the 10 years since I started with Dragon Naturally Speaking. They are great and sometimes sexy gadgets but when trying to reply to emails at 11:00 at night in some out of town hotel, the last thing I want to do is worry about whether the device’s battery is charged.
    For travel, I’ve found the perfect combination…an Olympus ME52 microphone (about the size of the end of your small finger), a 6′ wire combined with a small USB “converter” which changes the analogue (analog?) sound to digital. Weights less than 5 ounces, costs about $75.00 for the mike and the converter (Buddy, Andrea both make them). The mike clips to your shirt.
    I buy almost every gadget that comes along but when it comes to getting work done, I’ll take something simple that always works.

    I use Mac Speech with Plantronics S60 USB every day with outstanding results.

    Ditto on the Plantronics.

    I bought the Plantronics Calisto Headset + Bluetooth USB Adaptor in response to a MacSpeech promotional a couple of months ago. Unfortunately, I haven’t used it enough with Dictate to comment. But I use it daily for my VoIP phone, and I have no complaints about it function.
    However, I have had a replacement headset break just like the original one that I purchased: A small bit of plastic breaks off the bottom of the hinge on the ear loop. This allows the headset to flop away from the face and head, making if fit less securely and making it more difficult to keep it in close proximity to the mouth.
    I appreciate Plantronics’s prompt replacement under warranty the first time this happened. But the small defect is a big nuisance with an otherwise highly recommended product.

    Having problems with the plantronics dongle (BUA100) on iMac 27″ i7 and MacSpeech Dictate version 1.5.9. The dongle simply doesn’t work. Got a substitute dongle (plantronics BUA200) which doesn’t work, too.
    Is there any advice? As I’m not the only one facing the problem, I’d really be grateful for a solution that works.
