New SpeechMatic MultiAdapter USB Soundcard Can Potentially Increase Your Speech Recognition Accuracy
Have you noticed how the blue bar bounces up and down as you are running the Dragon Audio Check? Our voices never maintain a steady volume level so Dragon has to make an educated guess which means that potentially, our accuracy is never quite as good as it could be.
From a speech recognition point of view, USB soundcards have remained virtually unchanged since their inception in the late 90s. While some of the latest models include pretty blinking LED lights, low noise floors and high fidelity output, none of these innovations are relevant to speech recognition and that’s why, until now, we have been hesitant to publish a USB soundcard review. Fortunately, that’s all changed.
We have always endorsed the use of external USB soundcards or USB microphones but as of today, the only USB soundcard we will be recommending is the SpeechMatic MultiAdapter (due August 22, 2013) because it not only includes auto gain control but additionally includes auto EQ to compensate for vocal tonal changes that occur when speaking at lower or higher volume levels or extending or shortening the microphone distance. Besides being the only USB soundcard to include auto volume/EQ, it will also features global broadband noise filtering, a de-clicking algorithm (to block non-words such as clearing your throat) and NaturallySpeaking 11/12 algorithms impregnated onto an integrated circuit board. This new USB soundcard, which we have been testing for the last 6 months, is introducing 6 new technologies which you’ll find covered in our KnowBrainer Soundcard Face-Off ~ http://www.knowbrainer.com/downloads/Battle_of_the_USB_Soundcards.pdf but the bottom line is we found the new SpeechMatic MultiAdapter increased our speech recognition accuracy by approximately 1% over other soundcards. 1% may not sound like much until you realize that raising your accuracy from 96% to 97% translates to more than 25% fewer misrecognitions. To demonstrate this new technology, we were able to place our headset, approximately 12 inches away on our desktop, and continue dictating. Although our accuracy dropped a bit, we know of few other headset microphones that could be used from 12 inches away.
