The current 4 step process involved in the production of the DAISY TTS TV listings is as follows:
- The XML files are received from the UK Publishers Association
- These are converted to the RNIB XML format
- The RNIB XML files are processed through in-house software (called transforms) which create the DAISY structure and deal with acronyms, "videoplus" numbers and other "awkward" content
- The file is then processed through another piece of in-house software called WinDiss which creates the audio using rVoice TTS (Rhetorical) and deals with the SMIL synchronisation
The DAISY TV Listings are completed with 25 hours of audio on one CD covering UK terrestrial, cable and satellite channels. This process takes approximately three hours of production time. RNIB is currently reviewing many of the tools used within this process.
