For a variety of reasons I am very interested in having audio versions of various texts. In some cases I can get these texts in LaTeX format (with equations). Obviously I can use "normal" text-to-speech programs for reading ascii plain text or pdf/ps OCR produced ascii. Unfortunately this renders the mathematics nearly unintelligible.
Are there are any programs or packages specifically designed for rendering either TeX code generally, or math-oriented TeX code specifically, into text-to-speech friendly forms?
