The spoken voice is perhaps the simplest, not requiring much, if any, mixing. The free programme I mentioned above is more than adequate.
A singing voice would be a little more demanding and would maybe require one of the more dedicated programmes, up to the CuBase, Steinberg, etc, level.
In any case, you may find you need a small microphone mixer to change the microphone signal into 'line in' signal.
You may already know the above, but I thought I'd mention it, just in case.
