comment How do I keep Speak[] from spelling out words?
I'm pretty sure Speak uses the native OS text-to-speech engine. So whatever that happens to do with the parsed SpokenString is what you are going to get. Not sure how to verify that this is the case but if so, perhaps there is some system-level setting that would fix the issue.

comment Why is TimeSeriesForecast linear?
That's odd. It returns a model for me. I'm using 10.1 on windows 7.

comment Why is TimeSeriesForecast linear?
Incidentally a second order trend can be achieved in several ways but the following will let it automatically pick the orders of AR and MA components. TimeSeriesModelFit[data,{"ARIMA",2}]. A word of warning though, a second order trend is rarely a good idea in practice

It may be that a second order trend is needed. That said, if TSMF could reliably forecast stocks WRI wouldn't release it to the public :p

What version are you using? On version 10.2 I don't see this.

comment How to pick a color differing significantly from the colors already in a given color list?
Any reason why you couldn't use a pre-defined color space? Table[ColorData["BrightBands"][i], {i, 0, 1, .1}] There are a number of both continuous and discrete sets.

comment should Variance of EmpiricalDistribution include Bessel correction? (it doesn't)
Also, since empirical distribution works with weights and censored data the concept of sample size isn't always clear.

comment should Variance of EmpiricalDistribution include Bessel correction? (it doesn't)
The decision was made in order to maintain a consistency with the rest of the distributions framework. If you want the sample variance it seems easy enough to obtain.

Great! Glad to help.
