Continuing yesterday's exhaustive discussion of the Sony ICD-MX20 recorder I'm using for input to my speech-recognition software, it may be worth clarifying my use of the term high fidelity in the decidedly lo-fi context of human speech. In the larger realm of hi-fi audio, this recorder's 60-13,500 Hz frequency response is laughable; it's a far cry from the 20-20,000 Hz response that defines the minimum qualifications of any recording or playback equipment suitable for the world of music.

I'm not ready to render a final verdict on the NaturallySpeaking software I've been trying out since just after Christmas; I want to make sure I've held up my end of the bargain—e.g. training, and trying not to fluff my lines—before I do that. But at this point I think I can say something about the digital recorder I'm using as my audio input device.
