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
Braille Music

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
