voice recognition

Training this software takes quite a long time; a few hours if you want to get maximum performance. I actually wouldn't mind so much, except that you need to retrain it every time you buy a new microphone or work in an environment with a different sound level. For me, this has meant having to train the software several times. Reading the provided material so the software can sample your voice is actually kind of fun, but after you've done it a few times, it is exceptionally tedious.

The headphones which come with the software are adequate, but I've heard you can get better recognition with a higher quality set.

My biggest complaint about the software is that it consumes a tremendous amount of system resources on your computer. I can not be running any other programs at the same time, or it crashes. I am using a computer with a 1.40 GHz Centrino processor with 512MB of RAM. Even when I am running only IBM ViaVoice and MS Word, I clearly run into performance issues. After a while my computer starts to bog down and I have to restart it.

Another complaint is that it types with unusual quirks which it seems it would have been easy for IBM to have prevented. For example, it often fails to capitalize the first word in a sentence, especially when dictating in chat software. And for some reason, when you dictate for a passage to be in quotation marks, it leaves a space between the quotation marks and the words inside the quote. And sometimes, for some words, it is impossible to get the software to recognize that you are dictating a word, and not issuing a command.

IBM's ViaVoice is considerably cheaper than the competition. Unfortunately, I have no idea if the higher price of the competing products is justified by being a higher-quality product. ViaVoice is probably adequate for most casual dictating needs. If you've never used dictation software before, it's really impressive the way it can usually understand what you're saying. The more you use it, the better it gets at recognizing what you are saying, and the better you will get to at enunciating in a way it can understand. After a few months of casual usage, I would say my software is hitting 90 to 95% accuracy.

The bottom line is, for the price, this is pretty good software (though I sure do wish it was more stable). If you use dictation a lot and know that the competing products are better quality, they would be worth the price. But for a casual user, this software is fine.
