Optimal Notebook or Tablet Hardware
Submitted by JKroner on Wed, 07/25/2007 - 16:37.
I will be purchasing a notebook or tablet and seeking to install optimal hardware for DNS recognition speed. Since this will be the only "demanding" application, I would like to put my money where it will do the most good, but not overspend.
For starters, I assume a USB microphone eliminates the need to upgrade to a separate sound card? Yes?
I notice also with my current configuration that my DNS 8.0 does not use much RAM, but I don't know whether the extra expense of faster (rather than more) RAM would have made a difference. Is this addressed elsewhere?
Similarly, is there anything online that would show me recognition speed improvement from a faster hard drive, or charts that show faster processing with different CPUs. Similar information is shown for other applications on Tomshardware, but it's not clear to me that the demands of these applications correlate to DNS. See for example,
http://www.tomshardware.com/2007/07/16/cpu_charts_...
It seems there are two possible bottlenecks -- looking up the dictionary on the hard drive and then processing. I would like to balance my system so that I don't spend an extra few hundred dollars on a CPU only to have DNS kept back because the hard drive is too slow, or vice versa.
Thank you.

You will be happy with the fastest Core 2 Duo you can afford. Consider 2 GB of RAM as ideal.

Many notebooks manufactured today actually have pretty good sound cards built-in. The two advantages to having a good USB sound input with a good microphone also specifically designed for speech recognition, are that you are assured of the best audio input and if you ever want to move your speech files to another computer, you will have the exact same audio input and do not need to retrain.

although Dragon version 8 does not require as much RAM as Dragon version 9, you'll probably be getting Microsoft Vista at some point and two gig of RAM is the sweet point. With a notebook computer you probably will not have much choice of RAM type.

In our opinion a faster hard drive today is not necessary. Also, any Core 2 Duo will run Dragon just about as fast as possible.

As Marty notes, hard drive
As Marty notes, hard drive speed only affects DNS at load up and shut down, provided you have a reasonable amount of RAM -- at least 1GB with XP, probably 2GB with Vista. Basically, more CPU speed means faster DNS operation. Intel CPU's are much better than AMD CPU's these days. Memory speed and timing have minor effects on DNS's operation -- you'd be better off buying a step faster CPU rather than a slower CPU and faster memory. Above all, don't sweat the details -- whatever you buy today will be "obsolete" six months down the road. Pimping out a maxi rig for a year's operation is probably no better than renewing a run of the mill machine every six months
Now as ever, your time is much more effectively spent on learning how to get max results out of DNS than worrying about the minute details of your hardware.

Well said........ and oh so true!
