structure, file naming and some known problems on the
labelling. Possible improvements are proposed in the TODO section.

== Content: ==
* wavs: segmented audio (except part4, unsegmented, and part5 partially
segmented)
* text: prompts corresponding to audio
* lists: recommended training / development / test sets
* labs: aligned HTS labels
* emph_labs: aligned HTS labels with emphasis mark on emphasised word
  (P:0 for neutral words, P:1 for emphasised words)
* other:
  - prompts gathered in big files
  - question file to use in HTS training when using provided labels


== Syntax of file names: ==
* For part 1,2,3 and 5:
  [style]_[type]_[session]_[id].[ext] where:
  - style = neutral (neut) / emphasised (emph) / expressive (expr)
  - type = parliament (parl) / book (book) / siwis (siwis) / sus (sus) /
chapter (chap)
  - session = 2 digits
  - id = 4 digits
  - ext = wav / txt / lab
* part4:
  chap_full.[ext]


== Notes: ==
* Part 1 to 4 are from the same (main) speaker.
* Part 5 is uttered by a different speaker.
* Part 1 to 3 have labels.
* Part 4 and 5 do not have labels because they are not segmented.


== Known problems: ==
* The [s] sounds in "c'est" are often (if not always) replaced by
  [k]. This is a problem in the generation of labels.
* It may happen that some emphasised words are not labelled as
  emphasised in the case of multiple emphasised words in the sentence.


== TODO: ==
* Instead of just labels on known emphasised words, also add
  information about position of emphasised word relatively to the
  current word, for instance.
