Speech synthesis

  • from pitch, formant, and intensity
  • articulatory synthesis
  • Klatt acoustic synthesis

Speech analysis

  • spectral analysis (spectrograms)
  • pitch analysis
  • formant analysis
  • intensity analysis
  • jitter, shimmer, voice breaks
  • cochleagram
  • excitation pattern

Listening experiments

  • identification and discrimination tests

Labelling and segmentation

  • label intervals and time points on multiple tiers
  • use phonetic alphabet
  • use sound files up to 2 gigabytes (3 hours)

Speech manipulation

  • change pitch and duration contours
  • filtering

Labelling and segmentation

  • label intervals and time points on multiple tiers
