Bluetooth using Jawbone headset with DNS: working but can I improve it?
Submitted by snsok on Sun, 09/30/2007 - 18:28.
After about 4 hours of diddling with my laptop, I finally have my Jawbone bluetooth headset working. If anyone is not familiar with the Jawbone, I suggest you look at the specs and the demo here: www.jawbone.com The noise cancellation feature really works as shown in the demo.
I need to be sure I have set it up correctly as a bluetooth microphone, however. After doing audio setup, I get an Signal-to-noise ratio of 28, which is the highest I have had with any microphone. Nonetheless, I notice a crackliness upon playback, much like when a station on the radio is just slightly out of tune. There is NO static noise when I am not speaking.
The properties of this user are Bluetooth Microphone, Bluetooth 8 kHz.
Are there any other adjustments I need to make in the Sound console to improve fidelity? Yes, I know that this device isn't optimal for DNS but I just want to be sure I've maximized it.

By the way, I am currently using the Jawbone to dictate this particular message. I wish the recognition were better, but it is basically acceptable, though not as goodas with my noise canceling microphone. However, it is something I can easily wear while I work.

We hate to see anyone settle
We hate to see anyone settle for acceptable accuracy because it means spending a lot more time correcting. If you want extreme comfort (no headset to deal with whatsoever) and significantly higher accuracy you might want to check out the Revolabs xTag wireless lapel microphone.

How is it working for you in terms of accuracy?
The properties of this user are Bluetooth Microphone, Bluetooth 8 kHz.
From the above, it is setup optimally.

Marty,Lunis:
It is hard to say how good the accuracy is in percentage terms because I haven't used this long enough. I will also have to use it in a work situation where it is quite noisy. I do have to dictate more slowly and more precisely because the microphone is much less forgiving. With deliberate dictation, I am getting better accuracy than when I dictated at the same style and tempo as my regular microphone, which is a Philips SpeechMike.
In the above paragraph, the only correction I had to make was the name "Marty" which it got as "Monday."
All this may wind up being a waste of time but it has been a lot of fun.

Did you create a new user profile with the Bluetooth Microphone as the Dictation Source and then click the Advanced button to the right of the Vocabulary field and in the Speech model drop down list select Bluetooth 8 kHz?

Yes, that's exactly what I did.
I can't understand why voice with the Jawbone via Bluetooth on the cellphone sounds so good, and why it sounds so bad during playback in Dragon.
I use SpinVox for memo-taking on the cellphone. YOu dictate to Spinvox over the cellphone. It's in the UK. I mentioned its great accuracy in speech recognition, and that recognition is equally good using the Jawbone or just speaking into my cellphone.
I am sure there is a technical explanation. It bugs me that the Jawbone performs well outside of Dragon/PC.
PS: I did Sound Recorded with the Jawbone on the PC, converted the format to 8 kHz, and it also sounds crackly.

Instructions for Jawbone installation on XP
Hello Stan,
you said that you achieved to install the Jawbone on your laptop. Could you please give me some instructions. I am trying since two days without any success. I run Windows XP on a Macbook Pro (Boot Camp). The bluetooth stack in XP recogizes the Jawbone, I can enter the key (0000), but nothing else is possible. Do you have another bluetooth software?
Thanks in advance for any hint

Noe, The bluetooth hardware
Noe,
The bluetooth hardware is built into my IBM Thinkpad laptop. For some reason, the pre-loaded software allowed pairing with the Jawbone, but didn't provide headset services. So the Jawbone didn't know how to be a bluetooth microphone.
I upgraded the bluetooth software and then when the Jawbone paired, it did work as a microphone.
If you see Bluetooth devices in Control Panel, look at the properties of your Jawbone after it's paired, and see if you see Headset Services under the services tab.

Stan,
As I understand from this thread, you are using the Bluetooth capabilities and the sound card of the IBM notebook.
Is there any way to use a USB sound card and a USB Bluetooth device with JawBone?

Tee,
That's an interesting thought.
But I think a USB card converts analog audio into digital and then feeds it into the computer via a USB port.
The audio coming in through a Bluetooth mike to the Bluetooth device with headset services enabled in the computer is already digital.
That's my simplistic take on it.

A USB Bluetooth dongle is a Bluetooth radio receiver that just uses the USB port to insert the digital signal from the Bluetooth headset.
What I believe Tee is saying, and if so I agree, the problem may be with the Bluetooth stacks/protocols built into your computer. The Bluetooth USB dongle bypasses these.
