Talking music definition and existing products

• Spoken music or talking score is the speech
  representation of music score contents
• Products
• The description of the solution which come from
  RNIB
• The product talking music for DEDICON
• No-C-Notes

Talking music some questions

• Who the talking music users are ?
• Which kind of music is involved in these products
• Which is the information delivered
• How the information is delivered
• How synchronizations are done with the sound or
  with Braille
• Which the navigation possibilities are

BMML and metadata XBMML

• BMML has been designed to
• Encode Braille music notation
• Facilitate conversion from and to other music
  encoding
• Be extended to Braille music variants
• Metadata
• Dublin core, Marc
• Specific metadata number of character by line,
  number of line by page

Conclusion and perspective

• Automatic transcription using XSLT is possible
• Work to do
• Metadata xBMML BMML metadata
• Design the possible synchronisation with sound
  and Braille
• Design the navigation
