Offset cycles Onset cycles All phonation types
12 normal French speakers (6 women & 6 men)
4 consonants with voicing & manner contrast
7 phonations types : spontaneous (baseline), low or high, soft or loud & breathy or pressed
Control of intra-speaker difference to baseline for pitch (F0), intensity (SLP) & quality (H1-H2)
24 trains of 8 syllables, like "pafavabapafavaba"
For each, selection of the 4 central consonants
Measure of the relative fundamental frequency on the 10 cycles of the vowel offset & onset

Relative fundamental frequency
of voiced and voiceless stops and fricatives
for different phonation types in normal French speakers
This study was conducted thanks to the financial support of the region Provence-Alpes-Côte d’Azur and the compagny SQ-Lab
Low-soft-breathy phonation
Δ F0 (ST) Δ SPL (dB) Δ H1-H2 (dB)
Low -3.5 -0.4 -0.1 n = 11
Soft -2.8 -8.8 +2.7 n = 11
Breathy -0.9 -5.8 +6.3 n = 9

High-loud-pressed phonation
Δ F0 (ST) Δ SPL (dB) Δ H1-H2 (dB)
High +6.3 +3.2 -1.3 n = 9
Loud +5.2 +11.7 -5.1 n = 10

Fundametal frequency (F0) at vowel offset & onset higher for voiceless than for voiced consonants [1-3]
Relative fundamental frequency (RFF) used to assess vocal effort in patients with more effort for lower RFF [4-7]
To explore RFF variations according
to the voicing & the manner contrasts
… & to the phonation types known to involve different levels of vocal effort
To provide data for normal speakers
RFF values will be lower for voiced than for voiceless stops & fricatives
RFF values will be lower for high, loud & pressed phonations (more vocal effort) than for low, soft &
breathy phonation (less vocal effort)

Offset cycles Onset cycles
Measure of 10 periods (time between 2 pulses) at vowel offset & onset
Calcul of the instantaneous fundamental frequencies (F0) = 1/period
Conversion of all frequencies from Hertz (Hz) to Semitones (ST)
Calcul of the relative fundamental frequency (RFF) to the farthest point from the consonant (cycle 1 in vowel offset & cycle 10 in vowel onset)
RFF varies with vocal effort: higher RFF/lower effort in LSB phonation (+ voiceless consonants) & lower RFF/higher effort in HLP phonation (+ voiced consonants)
Possible to decrease but not to increase the vocal effort for voiced consonants &
possible to increase but not to decrease the vocal effort for voiceless consonants
In spontaneous phonation: production of voiced consonants at their maximum vocal effort but production of voiceless consonants at their minimum vocal effort
Background Purposes Hypotheses
Discussion
Methodology
Results
RFF lower for voiced than for voiceless stops & fricatives at vowel onset
RFF for voiced consonants: (except /b/ at onset: LSB > Baseline > HLP) Low-soft-breathy phonation > Baseline = High-loud-pressed phonation
RFF for voiceless consonant: (except /p/ at offset: LSB > Baseline = HLP) Low-soft-breathy phonation = Baseline > High-loud-pressed phonation
LSB phonation Baseline HLP phonation
