LOBE systems use true "speech recognition specification" microphone elememnts.
Their frequency response is from 40kHz to 22.5kHz, ± 4db. Microsoft's operating system recognizer(s) now sample speech at 16kHz. Since the LOBE samples the analog sound from the microphone at 22.5kHz, the audio bandwidth it provides to Windows Speech Recognition is slightly more than what the optimum audio input bandwidth calls for. Other wireless headsets' (typically) frequency response is approx. 7kHz - 8kHz. This means they can only provide Windows Speech Recognition about 3.5kHz to 4kHz of sampled audio bandwidth: About one half of what today's new Windows Speech Recognition systems are designed to use. The LOBE is the only self-contained, lightweight wireless digital headset that gives Windows Speech Recognition all the audio bandwidth it is listening for.. Unlike any other wireless digital headset. |
