What do you need to know about free software?
SoundSpectrum was founded in 2000 to take music visualization software to a new level, and our mission is to offer an unparalleled visual experience while listening to music. We create visual poetry.
Today, SoundSpectrum is a leading provider of real-time audio visualization applications, featuring the world-known G-Force, SoftSkies, Aeon, and WhiteCap visualizers.
G-Force is the most dynamic and sophisticated, yet entirely artistic, music visualization available. This is a direct result of creator Andy O'Meara's strong roots in mathematics and computing theory, combined with a passion for music and visual art. If you've seen G-Force in action, you know this isn't an exaggeration, as many users will tell you.
SoftSkies is a music visualizer and screensaver that produces mood-enhancing animated cloudscapes, rich with color and realistic motion. SoftSkies features professional color design, patent-pending cloud animation, dynamic image scenery and fine-grained visual control.
WhiteCap is a real-time music visualization plug-in for media players that features hundreds of stunning 'wireframe' effects and animated backgrounds, designed to be visually engaging and extremely dynamic.
Aeon, SoundSpectrum's latest product, represents a new dimension in music visualization, rich with content variety, color, and artistic depth. Aeon features an extensive library of visual content that uses SoundSpectrum's advanced internal drawing API designed to deliver high-performance graphics for OpenGL, OpenGLES, and Direct3D based platforms. Aeon's content base is unique, open, platform independent, and ever-growing.
Shogun 2 korean invasion mod. SoundSpectrum Darkroom is a utility application which allows you to export G-Force and WhiteCap output as QuickTime video files. Currently, SoundSpectrum Darkroom is under development on both Windows and Mac OS X platforms.
Digital connectivity and computing hardware are opening new doors for digital artists, but these doors can't be opened without continuous research and development. Free trial versions of our products will always be available, but our enhanced Gold and Platium versions offer the best experience and provide much greater visual capability and enhanced features, as well as support our efforts towards improvements and further product development.
Pleasecontact usif you have suggestions, ideas, or feedback — help us make visual products always one step ahead of your imagination.

One question I've seen asked a few times on this sub is how to generate a youtube visualization of a track you've created. The usual answer is to learn After Effects, but if you are a cheapskate like me there is this free tool for a bare-bones video: http://soniccandle.sourceforge.net/
The tool is java based and will render a bar animation over a static background. You get a selection of different bar styles and a color but that's about it for customization. Here's a video I made as an example: https://www.youtube.com/watch?v=TIFxtndlH5Q
So, it's not going to be confused for a trap nation vid, but it's a quick & free way to turn your existing tracks into something you can post on yt!
(It might sound like I am being critical of this tool but I really like it. Straghtforward, easy to use, does what it is designed to do effectively.)

I have a friend which helps children with speaking disabilities, and she needs some software that shows the amplitude of the sound immediately as the children speak through the microphone.
I have tried Audacity, but it has a delay of about one second.
Any recommendations on such software?
Note that the OS is Microsoft, and the software should preferably be freeware.

No idea if this is any use for you - it's Open Source:

SFS/RTSPECT
Just found this too:
Windows Tool for Real-time Waveforms & Spectra
RTSPECT is a free program for displaying a real time waveform and spectrum display of an audio signal. With RTSPECT you can monitor the waveform and spectral shape of sounds being played into the computer's microphone or line input ports. RTSPECT can display one or two-channel audio signals.

Audacity does allow you to monitor the input from the mic without recording. Don't know if this would reduce/eliminate the delay you experienced, though:
'either select 'Monitor Input' from the input meter's pop-up menu, or else just click on the input meter.' http://audacity.sourceforge.net/onlinehelp-1.2/toolbar_meter.htm

A few other options from this question, particularly useful if you need something with few dependencies and easy to modify:

Here's another free one. Shows a good spectrum with unnoticeable latency. Also has peak level indicators.

With ' Alchemy - Open Drawing Project http://al.chemy.org/ ' you can use your mouse to DRAW the input sound waveform onto a canvas, even curve its shape. It is in vector form and is saved as an image. Speed can be increased by the movement of the wrist.

Using the Volume Mixer isn't enough (right-click the speaker icon in the taskbar and select 'Volume Mixer')? It will show level meters for all sounds being played through the system, and should include microphones as well.

There are always delays in software when you do this sort of analysis on a computer. Unless you're using a high-speed driver such as those included with the Creative Audigy or X-Fi cards which are tuned for real-time performance capabilities.

Here's a commercial offering that I found in a quick Google search, which offers a 30-day trial download so you can try it for free first to determine if it meets your needs (you mentioned that there's a preference for freeware, but not that free is a requirement):
