Basic introduction
Praat (speech learning software) can analyze and annotate speech signals. After recording or reading audio files in Praat, it can display the following speech maps according to user requirements, such as three-dimensional speech maps, spectrum slices, pitch curves, and resonance. Peak curves, sound intensity curves, etc., all speech graphics can be drawn into exquisite vector graphics, and the corresponding object data can also be saved as disk files. In addition to intuitive language pictures, Praat (voice learning software) can also obtain various text information through calculation of signal data, such as pitch, duration, first or second formant frequency values, etc., and can also be used as needed. The output is in the appropriate form.
Function introduction
Voice experiments: voice analysis, multiple forced choice experiments, filtering, sound source filter synthesis, pronunciation synthesis, etc.
Auxiliary teaching: feedforward neural network, optimization theory learning, etc.
Statistical analysis: principal component analysis, multidimensional scale, discriminant analysis, etc.
