(18) Two sentence types were voiced throughout, and two contained unvoiced consonants.
(19) Results suggested that hypotonic laryngeal muscles in ATAXICs might result in prolongation of unvoiced interval, but that prolonged voiced interval related to biased hypertonus of laryngeal adductor.
Voiceless
Definition:
(a.) Having no voice, utterance, or vote; silent; mute; dumb.
(a.) Not sounded with voice; as, a voiceless consonant; surd.
Example Sentences:

(4) As expected, glottal vibration extended over a longer time in the obstruent interval for voiced fricatives than for voiceless fricatives, and there were more extensive transitions of the first formant adjacent to voiced fricatives than for the voiceless cognates.
(5) The following became clear after the investigation: (1) even by the age of 20 her auditory defect had not improved significantly; (2) from an early stage she could not identify either vowels or consonant-vowel syllables; (3) later she had no difficulty identifying vowels, but her consonant-discrimination score hardly improved; and (4) her problem in consonant identification was unique in that she could discriminate between the voiced and voiceless group but had great difficulty identifying the consonants within each group.
(6) Who is more voiceless in Syria now than the children?
(7) It was suggested that the degree and timing of PCA activity were directly responsible for determining the size and temporal course of the glottal opening for voiceless segments, although the suppression of the adductors might also have to be taken into consideration for a complete description of voiceless segment production.
(8) Speakers in the two hypernasal groups, however, showed smaller differences between vowel durations in voiced and voiceless stop environments than did speakers without cleft palate.
(9) This project examined modeled velopharyngeal orifice area estimation under conditions simulating voiceless stop consonant production in the presence of nasal airway obstruction.
(10) However, the contour which was predicted to result in more voiceless judgments also ended at a higher F0 in the vowel, and another effect of voicing is that the F0 is higher throughout the vowel after voiceless stops.
(11) Rather than splicing stimulus words (and trigger pulse needed for computer averaging) onto sentence stems, consonant-vowel-consonant (CVC) monosyllablic words were selected with voiceless stop consonants in the word initial position.
(12) Then they felt powerless and voiceless – and now?
(13) Both first formant (F1) transition duration and F1 onset frequency have been proposed to be perceptually significant in categorization of voiced and voiceless syllable-initial stops.
