My experience has been a bit different. The software I've played with "learns" the user's voice by recognizing frequency and tonality patterns. You can "re-train" it for other voices as well. Audio signals which don't match the patterns are filtered out. Additionally, use of a microphone w/ a very tight directional pattern (hyper-cardioid being the tightest) should filter out most of the background. An omni-directional would give the worst results.
