Incoming/recording sound volume much too soft/low when routed through USB audio

Description
I have a half-dozen USB audio cards, which I use primarily for speech recognition applications and video chat. They all behave about the same. The volume I hear from the other end is fine. But the incoming volume, the volume of my voice, is set much too low. I have to speak loudly in a telephone conversation, and talk to my speech recognition as if it were across the room. Google's speech recognition application is particularly problematic. If I use NaturallySpeaking running under wine, things are a bit better because the program compensates more. But the incoming speech recognition should be much more sensitive than it is, since users using voice/speech recognition do not want to strain their voices when using the product over a long period of time. Plus, it is rude to the other people in the room if I have to yell. It appears that the incoming sound level is set to record a garage band or the like, and not the human voice.
Curiously, I get better recognition through a bluetooth telephone headset than I do through a wired (and expensive) Andrea Pureaudio USB and Speechware Fleximike.
