The resultant output of the MCP will be a MathSpeak™ product composed of an electronic file and an audio track. This will be rendered both visually and aurally by the addition of a MathSpeak™ rendering module to an existing gh product called the gh PLAYER™ for Digital Talking Books. The gh PLAYER™ is a Section 508 DAISY 3.0/NISO-compliant playback software for Digital Talking Books (DTBs) designed to provide persons with print disabilities the most powerful reading experience. The gh PLAYER™ enables users to read books with ease, save time finding information, improve reading productivity, and benefit from flexible reading solutions. This convenient software solution can take the form of six different modes, ranging from audio with structure to full text/full audio.

Technical Feasibility Concerns_

The method of encoding the mathematical information will be MathML, specifically utilizing both the Presentational and the Semantic set of elements and attributes. The ANSI/NISO committee has already approved MathML fragments as being compatible with the core DTBook specification. The method of rendering the information visually will use a Microsoft Internet Explorer widget with a proprietary gh math viewer. gh is currently a certified "MATvp Level 1" partner of Microsoft, and has access to the needed information to utilize Internet Explorer in this way. Synchronized highlighting will be done using a proprietary gh technology based on the SMIL 2.0 specification. The method of rendering the information aurally will use VoiceXML for speech synthesis using both proprietary gh voices and commercial TTS engines such as the AT&T NaturalSpeak™ and Scansoft RealSpeak™ voices (for which gh has or will obtain valid distribution licenses). All copyright and Digital Rights issues will be handled either by Mazer or by the textbook publisher. These partners have already proven the ability to secure Digital Rights on several non-math accessible content projects in the past.
