Text placeholders. Rather than use only one text placeholder per slide, use a separate placeholder for each block of text – before the first equation, between equations, and after the last equation.
Using other screen readers will produce less satisfactory output", or something to that effect. Then when the PowerPoint file is distributed, instructions would say "the output is optimized for XXXX screen reader. These things considered, it seems best to create a PowerPoint file that works as well as it can for a specified screen reader. In Presentation view, JAWS will read the alt text and NVDA will look inside the MathType equation and read the MathML contained therein, resulting in the equations each being read once, regardless of which editor you use. Thus, in design view (edit view), NVDA will read each equation twice. Trouble is, with NVDA, it sees the alt text and also understands the content of the MathType equation itself. If you're reading the slide with JAWS, that's what JAWS will read. PowerPoint allows you to add alt text to graphics, including MathType equation objects. It will be difficult if not impossible to understand a slide read in this manner. It will likely read all of the text first, then all of the equations next. Thus, if you use the normal "visual" method of typing text, leaving empty spots for the equations, and move the equations into position later, NVDA will not read the equations with the text. Since MathType equations are "floating" on a PowerPoint slide, they are not read in sequence with the text of a slide "placeholder" (the part of the slide where you type text).
Since there's no text to sequence with a display equation, specifying the order in which they are to be read is easier. A display equation is in a paragraph of its own, sometimes centered on the line. It's an equation that's part of your paragraph, and there is text before and sometimes after the equation. If you're not familiar with the terms inline equation and display equation, an inline equation is what its name suggests. That being the case, it's best if you can avoid inline equations to the extent possible, and stick with display equations. The equation editor Microsoft includes with PowerPoint does allow true inline equations, but those are not accessible. Thus inline MathType equations are problematic, regardless of whether they’re intended for sighted viewers or sight-impaired viewers. Unfortunately there is no such thing in PowerPoint as an inline object, objects being things such as MathType equations. Neither is required by JAWS, but more work is required on your part for creating slides that JAWS can read. With NVDA, you'll need both MathPlayer and MathType for the screen reader to read equations.
