Processing of the database

from speech and text to a prosodic database

automatic segmentation

• uses HMM speech recognition technology
• produces
  • word label files
  • syllable label files
  • phoneme label files
• from
  • speech
  • orthographic text

demo about automatic segmentation
details about automatic segmentation

automatic part-of-speech tagging

• Tagger developed at IMS (Helmut Schmid)
• a wrapper produces POS tag label files from word label files and orthography

details about Helmut Schmid's tagger

automatic ToBI-labelling

• automatic length extraction
  • pauses, syllables and phonemes
  • speaker and phoneme dependend normalization
• automatic intensity extraction
  • rms values for syllable nuclei
  • various sub band rms values to capture spectral tilt
  • speaker and phoneme dependend normalization
• automatic F0-parametrization
  • 7 parameters per syllable
  • parameters have phonetic interpretation
  • taylored for ToBI labelling
• prediction of the phonological prosodic labels (ToBI) (still work in progress)
  • symbolic attribute value pair learners
  • first order predicate learners

  details & demo about F0-parametrization

manual ToBI-labelling

• labelling guidelines
• training data for automatic labelling
• correction of errors of automatic procedure

see the labeling guide for our version of ToBI

selection and search utilities

news broadcast segmentation

• segments a news broadcast into news stories
• relies on prosodic and lexical marking

reoccuring news detection

• two methods of finding reoccuring news stories
• helps establishing a corpus of repeated speech
  for research on prosodic variation

ToBI overview with wordontones

• analyzes word and ToBI label files
• shows prosodic variation
• ToBI labels of different spoken versions appear under the orthography
• produces LaTeX and PostScript files ready for inclusion in publications
• also produces a HTMLversion for easy worldwide collaboration

see a clickable HTML output of wordontones

corpus search

• finds all occurences of a word in the corpus
• pops up an xwaves signal display with label files
• integration with xkwic planned for the future
