_popupControl(); When I first used speech two weeks ago  it worked fine but now it will not recognize anything. Dictating to it seems to open programs or commands only. It works fine in the training mode but will not accept dictation instead opening things like "programs" or word pad etc
 
Any suggestions??

Hi Mauries,

Welcome to the Forum!

Based on what you've described, it sounds like something has recently changed with your speech recognition setup as you mentioned it worked fine a couple of weeks ago.

Try and figure out what has changed... New/different microphone or sound card?  Try setting up your microphone again; where you read the passage "Peter dictates to his computer..."  Even try a little more training.

Let us know how it goes, if you don't have any good results, you may want to create a new speech profile (There's a file in the download section that explains how to do this).

My first thought is that you may be using a notebook computer with a built-in microphone. If this is the case, you may be using the built-in microphone without realizing it. First, make sure you have the microphone connected to the correct inputs for microphone and playback. These microphones do not generally work well but may be able to work issuing commands which do not require a large vocabulary. Right-click the speaker icon in the lower right taskbar next to the clock. Choose Recording Devices and make sure the microphone you are using, especially if it is a USB input, is set as the default device.
 
Now run the microphone setup configuration as suggested by Brad.

No I am using a desktop system and have tried several microphones. Each works fine with training but as soon as I try to dictate all it wants to do is open files!!!

No I have tried 2 microphones with similar results.
Dictating "Open word" will open a word document but any words after that only appear to open notepad, programs etc.  I am at a loss to exlain what has happened!!!

And what microphones are those? I'm not trying to be facetious. We have been speech recognition software/hardware providers for 14 years. It has been our experience that unless you have a really good microphone, tuned for the frequency range of the human voice, and able to reject background noise, you will not get optimal results. A less than good microphone may pass the audio setup, but will have difficulty with the smaller words because they have less acoustic information to go on and with commands because they are not used in context of surrounding words.

No I would have to say the microphone I am using is the less than $20 variety, however up until a couple of weeks ago it worked fine. I am quite happy to upgrade to a better mic/headset and would apprciate your suggestions

Have tried re-setting up your microphone at
Control Panel  -> Speech Recognition Options -> Set up Microphone

Since you said everything was working fine a couple of weeks ago, maybe this is the problem?

I would like to add to what Brad suggested.  If resetting up the microphone does not help, it is possible you microphone has developed a short or another defect.  You can test this by creating a windows sound recorder recording while jiggling the cable in various places.

Thanks guys, Tried the sound recording check and it works fine.  Been back and reconfigured the microphone but no change. The pussling part is that it will follow commands but refuses to listen to dictation!!!

Hi,
 
We have also a long experience in speech recognition; It's true: you can't obtain good results with a bad microphone. A nose cancelling system with a switch is required.
 
For the moment, the best one is the Plantronics USB AUDIO 650 (in France). I think around 40 S for you.
 
Best regards
 
Ps: Have a good election day!

Have you tested your Plantronics USB Audio to other microphones?
 
We've tested many Plantronics microphones.  In very quiet environments they work OK.  However, even with a little bit of noise, they cannot match better noise canceling microphones in our testing experiments.  The work group at Microsoft used to use Plantronics USB microphones and I believe they found out, especially a demonstrations, that these microphones do not work as well as some better microphones you can find listed on the MyMSSpeech.com website.

Hi Marty,
 

Thank you for your answer so fast! It's really nice to share our experiences through this forum. Really!

What USB microphone would you propose me unless 60? (It has to possess a switch).

We work with children and handicaped adults (dyslexia and dysphasia) in hospitals and schools and we have to propose affordable prices. At least, even with persons who have big difficulties to speak, we have excellent results with Plantronics 625 (we did not find better in France), even in a very noisy atmosphere. As you know, the experience shows us that the manners to use the software is very important.

2 headsets come to mind which in our testing provide higher noise canceling and better accuracy than the Plantronics. These are the:
1. The VXI TalkPro USB-100. Check out the 2 earphone USB-200 as well.
2. The Andrea ANC-700/USB soundpod Combo$aver. Check out the ANC-750 2 earphone model.
 
As mentioned, the Plantronics perform OK in a quiet environment. What microphones did you test in the high noise conditions? Did you notice a drop in accuracy with the Plantronics when noise levels increased?

Hi Marty,

Thank you for this information. The "VXI Pro talk" seems interesting. We will contact their dealer immediately in France. I will send you our results.

As regard to the noisy environment, Plantronics is not an ideal solution but we have not found better in our range of priceCry.

In fact, our problem is the following one:

- We have to propose reduced prices, because the children can break their microphone repeatedly in a school yearAngry,
- the system has to be nose cancelling, but, for a use at school,

- It has to allow to speak in a low voice (in the class room),
- It has to allow an adjustment so that the microphone is taken away from the center of the mouth and it has to allow an adjustment to the head of a child (the mic of the Plantronics is téléscopic)

- It has to possess a switch/mute (this allows to cut the microphone when the pupil does not speak, mainly in an noisy environment). So, in a class of school, as long as the pupil speaks, if the environment changes, it does not raise problem.

Best regards,
 
Gilles

Gilles,
 
It seems your client's special needs are stricter than most general business users. To summarize:
1. Extreme durability caused by rough usage
2. High noise canceling for a noisy school environment
3. High gain to pickup soft voices
4. On/mute switch
5. Reasonable Price
 
Having high gain and good noise canceling are conflicting properties from the view of the Laws of Physics. This is because if the microphone has a strong gain to pickup soft voices, it will also pickup background noise.
 
I believe your decision to test a VXI TalkPro USB (100 or 200) will come closest to meeting the requirements listed. VXI microphones have a 2 year warranty (most others have a one year warranty).
