SpeakQ Speech Assistive Technology vs Dragon NaturallySpeaking Voice Recognition Software

WordQ is assistive technology software that helps students write by predicting their next word as they type. SpeakQ is a plug-in for WordQ that adds speech recognition.

Sometimes students get stuck trying to spell a word because they are so wrong that they can’t find the word in the dictionary, and assistive technology can’t predict what word they’re trying to spell. For example, if you’re trying to spell the word “phonics” with an “F”, you’re out of luck.

SpeakQ is a nice add-on for WordQ because when students get stuck, they can simply click on the microphone and dictate the word to the computer.

If you visit the SpeakQ website, they market their voice-recognition software as “forgiving speech recognition” which is “more tolerant speech recognition for children, accents and speech difficulties and other software.” Does “forgiving” mean “less accurate”?

I use Dragon Naturally Speaking and Windows Live Writer to blog on this site. I also like comparing speech recognition software to see if I can find a better and more accurate product. Basically I evaluate voice software by reading the rainbow passage to my computer and then counting the number of words that the voice-recognition software misunderstands.

Dragon NaturallySpeaking is incredibly accurate. It usually gets around 97% of my words correct when I speak to my computer in a quiet room. SpeakQ seems pretty good, but I wonder how good it is compared to Dragon Speak. Here are the results of a quick comparison study.

Dragon Naturally Speaking: 98.8% word accuracy (5 word errors)

A few months ago, I read the rainbow passage to Dragon Naturally Speaking when I was trying to evaluate how effective the iPad dictation voice-recognition software was on the new iPad 3.

SpeakQ: 76.2% word accuracy (79 word errors)

There are 332 words in the rainbow passage text without including the title. SpeakQ made 79 word errors and 3 punctuation/capitalization errors. This means that SpeakQ recognized 76.2% of the words correctly (or 75.3% of the words correctly if you include punctuation and capitalization errors.)

SpeakQ (after rainbow passage training): 87.0% word accuracy (43 word errors)

One of the cool things about SpeakQ is that you can open your own text documents to train the SpeakQ software. I wanted to see how accurate SpeakQ could be if I trained it on the rainbow passage that I was using in my test.

After training SpeakQ on the exact same text that I dictated, SpeakQ still made 43 word errors and 9 punctuation and capitalization errors on the exact same rainbow passage that I trained it on. This means that SpeakQ transcribed 87.0% of the words correct (or only 84.3% of the words correct if you include punctuation and capitalization errors.)

Bottom line: Dragon NaturallySpeaking is more accurate than SpeakQ but that doesn’t necessarily mean you should get Dragon NaturallySpeaking. It all depends on why you want to talk to your computer.

Do you use WordQ in your classroom? Do you use the SpeakQ add-in as well? Leave a comment here.
