speech recognition isolated word hardware:

[vat123]

Hello friends,
I want to implement isolated word recognition on hardware( for digits 1-10)
suggest hardware for the same

Word recognition is best done on a PC with the appropriate software. Win7 has excellent recognition with minimal training and supports low error rates with a good mic in the proper position near the chin.

Have done software based work with over 90% accuracy.
now want to implement it using hardware but have no idea related to it, suggest development boards.

Hello!

If he's telling you he wants recognition on hardware, you know what? It's probably because
he wants recognition on hardware, not on PC.

That said:

It would be good to describe the software:
How much RAM do you need? How much program memory?
If you don't give the minimal information, it will be difficult to help you.
I guess some kind of ARM platform may make it, but... more detail
is needed.

Dora.

With a project like this it probably helps if you use a controller capable of doing more than just the basic recognition
without grinding to a halt just to do the recognition. Look for big MIPS to get decent speed.

You could take a look at microchips offerings but I'm not too impressed to be honest although their
dsPIC range should be good enough for basic recognition tasks - I'm not sure how they would cope
with speaker independant or word spotting tasks though.

There are a whole host of boards out there you could use for general purpose work so I guess it depends
of why you are doing it? Is it to develop and sell a board based product or just for fun?

Either way you could go the safe route and pick what everyone else is using or you could
get adventurous and pick something like a multi-core board - try: **broken link removed**

I havn't used either but the parallella looks interesting and probably has all the power you need
at a decent price to do a good job.

If you did branch out like that dont forget you'd be stuck for limited support and have to rely on
a relatively low number of other users.

Whatever you choose I can pretty much guarantee your 90% rate is going to fall off a cliff
if you dont pay very a_n_a_l attention to hardware design.

There's a good reason there isn't much voice controlled tech about - it's that "other" 10% that explains that.
