Bluetooth Headset and WSR (Windows Speech Recognition)
Several weeks ago we began testing the new VXI Xpressway Bluetooth headset. The VXI Xpressway Bluetooth headset samples at 16 kHz. However, being Bluetooth it seems that the low end and high-end frequencies dropped out somewhat and you get a fairly compressed range of the human voice. A couple of years ago, VXI worked with Nuance, the developer of Dragon NaturallySpeaking, and they were together able to create a Bluetooth language model and a designation for a Bluetooth microphone. Accuracy was actually quite good.
After thoroughly testing the VXI Xpressway Bluetooth headset with Dragon NaturallySpeaking I had high hopes it would work well with WSR (Windows Speech Recognition). I was quite disappointed because accuracy was approximately 80%, one or two mistakes every sentence. I went on to do many other things but it kept gnawing at me. Today I created a new user (named it Bluetooth) and did the first training. Enunciating clearly, not speaking particularly slow, accuracy rose to 95%. I corrected the paragraph, reread the paragraph, and attained 98%, two mistakes. Tomorrow I am going to do an additional training and see if that improves accuracy even more. I would say the additional training and careful enunciation made the difference.

We not only include a neoprene zippered carry bag, put in the Special Instructions box, “Send the WSRToolkit free of charge,” a $15.99 value. This offer is good until the end of the year.

Bluetooth Is Not Recommended for WSR
Nuance created a Bluetooth language model and a designation for a Bluetooth microphone.
We recommend against Martin's advice on using the BlueParrott Xpressway ~ http://www.knowbrainer.com/ShopOnline/index.cfm?fu... bluetooth wireless microphone in WSR. You can't force hardware to work in software that isn't designed for the task. Additionally, Nuance did not create a Bluetooth language model because it isn't physically possible. What's Nuance created was a specialized Bluetooth Acoustic Model which does not exist in WSR. It is unlikely that any Bluetooth microphone will work well in WSR until Microsoft develops their own Bluetooth Acoustic Model. Martin may have managed to eventually massage higher accuracy out of his user profile but at the cost of additional training which isn't a particularly good recommendation for any speech recognition application. Warnings against overtraining speech recognition applications have been covered in detail on various other speech recognition forums such as the KnowBrainer Speech Recognition Forums ~ http://www.knowbrainer.com/PubForum/ and this forum.
We can appreciate Martin's extra effort but the only speech recognition application we can recommend for the BlueParrott Xpressway is NaturallySpeaking. Anyone who purchases this microphone for WSR will most likely be disappointed. Martin even admits to having to work on making the Xpressway function in WSR. Personally, when we're shopping for a microphone, we like it to work right out of the box. Attempting to utilize extended training to compensate for the lack of a dedicated Bluetooth Acoustic Model is equivalent to spinning your wheels in the mud.
PS: We also include the same $2 thickly padded Neoprene Zippered Microphone Bag ~ http://www.knowbrainer.com/ShopOnline/index.cfm?fu...

Using the WSRToolkit found at:
http://www.mymsspeech.com/microphones/prod_details...
we did two things to the Bluetooth User Training we created yesterday:
1. We used the WSRToolkit's Add From File to parse twenty or so orthopedic medical reports. This feature improves the accuracy of your personal "Language Model." This works the same as Dragon's Add words from your documents feature.
2. Next we read two of the orthopedic reports to the WSRToolkit's “Train From Text” which improves the acoustic model (how you speak words) of the user profile.
I then read the two orthopedic reports referenced in 2 above. Of approximately 400 words there were four mistakes which works out to 99% accuracy.
Lunis Orcutt said, "Anyone who purchases this microphone for WSR will most likely be disappointed." He's also the person who said he could never recommend the other VXI Bluetooth which hundreds of people we have sold until have been using successfully the past two years. It does take some effort to discover how to make things work, but we at eMicrophones are more than happy to go the extra mile. Doing what I did above is what we normally do when we create a Dragon new user profile in terms of adding our typical documents. Taking a few minutes to read a couple of documents in order to use an inexpensive wireless microphone successfully is well worth the trouble to many people.

where it says:
"BBB- THE FOX GUARDING THE HEN HOUSE"
It has been reported to the "badbusinessbureau.com" that,
the BBB encourages and solicits money from the very businesses they monitor! How could this be beneficial to the consumer?
Consumers have reported, the BBB DOES NOT report consumer complaints which are under investigation, even when they know the business is under criminal investigation and is about to be shut down. ......(see victim's story down below)

This is where the organizer of the conference to which I was invited, giving legitimacy to my speech recognition credentials, said:
"I disagree with several of the comments made by Lunis about the purposes, attendees, and the character of the meeting; but since he wasn't invited and wasn't there I'll spare this audience those quibbles."

What does this have to do with WSR and Bluetooth microphone
We don't see what any of this has to do with Bluetooth microphone usage in WSR but we would be careful when inventing stories about how Larry Allen came to INVITE YOU to this conference, as well as why we were not there. You forgot to mention that he (Larry Allen, the conference organizer) made these statements in repudiation of your false accusation that we had been singled out to be BANNED from this conference when in fact we had simply not fallen into the particular category of VAR who would have had any reason to want to participate. You had been caught in a lie then and he publicly called you on it. Sound familiar? Detect a pattern?
Time to knock it off!!!
Hey guys,
This whole feud between the two of you has gone well beyond anything valuable or practical, and into the realm of the completely stupid and absurd.
Both of you knock it off. Regardless of who's doing what, I have my particular likes and respect for both of you. However, the extremes to which this is being taken is tantamount to a couple of six year olds arguing about whose daddy is bigger.
Put a lid on it.
