Speech Spectrogram & Formant Analysis

Setup of Profile „FFT_Speech_FOR“

Specify Mode ON/OFF:• Spectrogram• Fundamental Frequency

Analysis(autocorrelation method)

• Waveform Plot• Formants, show formants

ARI

Color and Line Stile

• Select Profile (Black and White)

• Specify spectrogram Palette (not shown) and Font Setting

• Color setting General

• Specify Function Lines Color and Line Stile for formant tracks (F1 = color #4, F2 = color #5 ….., see „Line“ in profile dialog)

Speech Formant Analysis

• Setup: Spectrogramfrequency range, amplitude range,spectrum type

• Setup: Fundamental Frequency Analysis(autocorrelation method)

• Setup: FormantsNote: if the number of coefficients is set to 0sampling frequency in kHz*1.25 is specified

Formants: copy to clipboard & statistics

• Copy formant and fundamental frequency values to clipboard for use in external programs (see further „export parameters“)• perform parameter values raw statistics.
