Speech analysis and manipulation software.

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
• use phonetic alphabet
• use sound files up to 2 gigabytes (3 hours)

Learning algorithms

• feedforward neural networks
• discrete and stochastic Optimality Theory

Statistics

• multidimensional scaling
• principal component analysis
• discriminant analysis

Graphics
