How to choose a microphone for SR
 

Hi,

I'm trying to do some research work in Speech Recognition. I just
notice that a good microphone is very important for the accurary rate.
It seems that USB headset with microphone is better. But it's too hard
for me to choose. Would you please recommend one for me? Price could
be $50 - $100. Thanks in advance!

You will find them all pretty similar. Choose on price and looks.
Choose one with a bendy arm, though, because the mic absolutely must
not be placed in front of the nose or mouth. It should be located at
the cheek, about an inch from the side of the mouth, between mouth and
nose heightwise.

The following are NOT USB - they plug into microphone/earphone sockets.

Logitech headset Dialog-812/stereo + Microphone - OEM - £6.48
http://www.ebuyer.com/product/48085

Logitech Dialog-811 Mono Headset & Microphone - 3.5mm Jack - OEM - £6.60
http://www.ebuyer.com/product/48087

Both work very well (check ebuyer's customers reviews on above links)

(I prefer the mono version as it leaves the other ear to answer the
telephone)

In audio work SR is the acknowledged acronym for *SOUND REINFORCEMENT*.

Please do NOT use it to mean something else.

Yes indeed. Sodium Ricinoleate - tingling fresh.
The SR advert was the first commercial shown on British
TV (not a lot of people know that:-.)

ISTR a Panorama showing what we had to look forward to when ITV started -

But Gibbs SR was indeed the first ad shown by ITV.

Not that I saw it - Grampian TV didn't start up until the '60s.

It seems that there were more than 20 contenders, and the lucky
winner (for the first ad to be shown) was drawn from a hat.

George Hersee. More to the point he was the chairman of the committee that
designed test-card F, the first one to have Carole's picture in it. George
had previously worked on test-cards D and E (the ones with sinusoidal,
rather than square-wave, frequency gratings).

The USB SR microphone I've used for several years with satisfactory
results is Andrea USB NC-7100. However, it requires a microphone
socket as well as the USB as it is fitted with a minijack for the
earphone's audio readback.

I've had other brands which didn't work as well, which is ironic as
the Andrea NC-7100 was essentially a "free" inclusion with IBM's
ViaVoice. I assume that the guys who wrote a speech recognition
programme eventually learned whatever there is to know about SR mikes
(1).

Note that even the NC-7100 is merely "satisfactory", not great. It
seems to me that at present SR applications depend more on the logic
of the software for a workable result than on the quality of the
mikes.

You don't say what sort of research into SR you want to do
(psychological, linguistic, technical, or possibly even medical) but I
confidently forecast that unless you have the patience of Job you will
soon be very frustrated with the quality of even the best available
mikes and just slightly less frustrated with the quality of the best
available software. I have used the best I could find, IBM's ViaVoice,
for years, and have never seen an error-free page; I can type and edit
3000 clean words in half the time it takes to dictate and clean up --
and that is on a good day. I guess a normal rate once you get the hang
of SR would be nearer 40% as fast as just using the keyboard from
scratch. SR is strictly for a) people who type with two fingers and
very slowly at that or b) ambidextrous multitaskers (I'm watching
MotoGP in a corner of my screen as I dictate this letter to you, while
polishing a novel in another window and listening to Sophie Yates play
the harpsichord on electrostatic earphones). In situations like b)
above, SR permits one to increase efficient use of time by adding an
additonal writing task or, at least theoretically, an additional
editing task to what one writes on a keyboard. The editing task is
strictly theoretical, because using SR to copy-edit material longer
than a couple of short pars will turn anyone into an axe murderer in
less time than it takes to read this sentence.

HTH. Good luck.

My life! What are you implying?

The rest of the commercials were shown soon after, and
IIRC the viewers (answers on a postcard please)
thought the Guinness ad was the best of all.
