Vocal fold collision threshold pressure: An alternative to phonation threshold pressure?Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract Phonation threshold pressure (PTP), frequently used for characterizing vocal fold properties, is often difficult to measure. This investigation analyses the lowest pressure initiating vocal fold collision (CTP). Microphone, electroglottograph (EGG), and oral pressure signals were recorded, before and after vocal warm-up, in 15 amateur singers, repeating the syllable /pa:/ at several fundamental frequencies with gradually decreasing vocal loudness. Subglottal pressure was estimated from oral pressure during the p-occlusion, using the audio and the EGG amplitudes as criteria for PTP and CTP. The coefficient of v...

Voice as a tool communicating intentions.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract The ability to understand speakers' intentions is examined for typically developing children (TDC), children with autism spectrum disorders (ASD), and children with attention deficit/hyperactivity disorder (ADHD). Four types of spoken phrases, expressing praise, sarcasm, blame, and banter, were presented, and subjects were asked to judge if the speaker praises you or not, or if she blames you or not. The children could correctly judge the speaker's intention for congruent phrases such as praise and blame. TDC younger than 8 years had significantly lower correct percent compared to the TDC older than them for t...

Perceptual evaluation of pathological voice quality: A comparative analysis between the RASATI and GRBASI scales.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract To provide mutual understanding between different evaluation scales for pathological voice quality, comparative analyses between the GRBASI and the RASATI systems were conducted. A total of 100 voice samples were rated by experienced Brazilian and Japanese listeners. Analysis by factor analysis with varimax rotation identified significant interrelations between the scales, with asthenia, instability, and roughness as the common factors. Grade-of-hoarseness, only included in GRBASI, corresponds to a combination of roughness, breathiness, and instability. Harshness, included only in RASATI, can be predicted by b...

Abstract The Gauffin and Sundberg technique of assessing masking during vocalization was modified and tested on 22 normal-hearing and 20 hearing-impaired subjects. The masking effect of the vocalized [a:] on narrow-band noise pulses (250-8,000 Hz) and on test reading was studied. The results showed that the female voice was about 4 dB more efficient in masking external speech compared to the male voice and that the female voice had a high-frequency bias of masking the narrow-band noise, whereas the male voice had a low-frequency bias. Subjects with hearing impairment in the high frequencies were particularly impaired b...

The movement of the diaphragm monitored by ultrasound imaging: Preliminary findings of diaphragm movements in classical singing.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This study will by ultrasound imaging (USI) investigate the movement of the diaphragm (DPH) during classical singing. Due to the complex structures of the DPH both the anterior and dorsal sections of the DPH will be investigated. The movement of the anterior section is surveyed by performing a transabdominal scan from the right hypochondrium. The movement of the dorsal section is surveyed by examining the movement of the left kidney. We conclude that USI is a promising tool for surveying the movement of the DPH. Especially the anterior section is easily assessed; however, also the dorsal section may indirectly be surveyed ...

Arytenoid adduction asymmetries in persons with and without voice disorders.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This study sought to determine if there were differences in arytenoid adduction asymmetry in persons with and without voice disorders. Three aspects of arytenoid adduction asymmetry were judged from still frames of the arytenoids in the adducted position from stroboscopy recordings of 52 vocally normal speakers and 54 persons with voice disorders. Asymmetry of the arytenoids was prevalent in both normophonic and dysphonic speakers. The lack of strong differences in the prevalence of arytenoid asymmetries in the adducted position between normophonic and dysphonic speakers suggests that caution should be taken when using the...

The voice source differs between modal and falsetto registers, but singers often try to reduce the associated timbral differences, some even doubting that there are any. A total of 54 vowel sounds sung in falsetto and modal register by 13 male more or less experienced choir singers were analyzed by inverse filtering and electroglottography. Closed quotient, maximum flow declination rate, peak-to-peak airflow amplitude, normalized amplitude quotient, and level difference between the two lowest source spectrum partials were determined, and systematic differences were found in all singers, regardless of experience of sing...

Voice onset time versus articulatory modeling for stop consonants.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Voice onset time (VOT) was developed as a parameter for the pattern-playback speech synthesizer developed approximately 50 years ago, in order to generate the acoustic effects of voiced-unvoiced differences in English stop consonants. However, problems arose when the VOT parameter was used to define stops in actual spoken language, to replace aerodynamic and physiological parameters. A representative physiological model from the same time-period that avoided these problems is sketched. In this model, the manner-of-articulation of a stop is determined by the duration, timing, and extent of laryngeal, articulatory, and r...

Noh voice quality.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
In Noh, a traditional performing art of Japan, extremely expressive voice quality is used to convey an emotional message. Aperiodicity of voice appears responsible for these special effects. Acoustic signals were recorded for selected portions of dramatic singing in order to study the acoustic effects of delicate voice control by a master of the Konparu school. Using a signal analysis-synthesis algorithm, TANDEM-STRAIGHT, to represent multiple candidates for pitch perception, signals deviating from the harmonic structure have been successfully displayed, corresponding to auditory impressions of pitch movements, even wh...

The effect of abdominal kinematic directives on respiratory behaviour in female classical singing.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Breathing instruction for classical singing is becoming more physiologically focused, yet the effect of chest-wall kinematic directives on breathing behaviour is largely unexplored. Five female classical singers sang Caccini's Ave Maria without directive and under two directives: 'steadily pull the abdomen inward' and 'steadily expand the abdomen' through each phrase. The directives had a statistically significant effect on chest-wall dimension at initiation of phrase and on excursion, but dimension at termination of each phrase reverted to habitual behaviour. Rib-cage dimensional change counteracted abdominal change s...

Laryngeal mechanisms in speech: The contributions of Jan Gauffin.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Jan Gauffin was an early user of fiber optics which allowed him to discover that laryngeal structures above the glottal level are involved in speech. His research led him to postulate three independently controlled mechanisms: fundamental frequency control, glottal adduction/abduction, and laryngealization, the latter derived from the protective closure function. He argued that phonetic theory must be revised to account for the main phonation types of the world's languages. He saw them as combinations of two interacting dimensions: adduction/abduction and laryngealization. Secondly he gave the aryepiglottic sphincter a...

Biomechanics of fundamental frequency regulation: Constitutive modeling of the vocal fold lamina propria.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Accurate characterization of biomechanical characteristics of the vocal fold is critical for understanding the regulation of vocal fundamental frequency (F (0)), which depends on the active control of the intrinsic laryngeal muscles as well as the passive biomechanical response of the vocal fold lamina propria. Specifically, the tissue stress-strain response and viscoelastic properties under cyclic tensile deformation are relevant, when the vocal folds are subjected to length and tension changes due to posturing. This paper describes a constitutive modeling approach quantifying the relationship between vocal fold stres...

Glottal inverse filtering with the closed-phase covariance analysis utilizing mathematical constraints in modelling of the vocal tract.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Closed-phase (CP) covariance analysis is a glottal inverse filtering method based on the estimation of the vocal tract with linear prediction (LP) during the closed phase of the vocal fold vibration cycle. Since the closed phase is typically short, the analysis is vulnerable with respect to the extraction of the covariance frame position. The present study proposes a modified CP algorithm based on imposing certain predefined values on the gains of the vocal tract inverse filter at angular frequencies of 0 and pi in optimizing filter coefficients. With these constraints, vocal tract models are less prone to show false l...

Text reading was recorded in working environments and analyzed for fundamental frequency (F0), equivalent sound level (Leq), alpha ratio, jitter, shimmer, and perceptual quality. Self-reports of vocal well-being were registered. In the VHL group, increased F0 and difficulty of phonation and in the VT group decreased perturbation, increased alpha ratio, easier phonation, and improved perceptual and self-reported voice qu...

The nature and severity of voice disorders in lung cancer patients.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This study examines the nature and severity of voice disorders in a set of lung cancer patients. Patients' concern for their voice, relative to other lung cancer symptoms, will also be examined. Voice assessment included both the patients' view (Voice Handicap Index) and expert clinicians' perceptual rating of voice quality (GRBAS). Additionally, visual analogue scales measured how much patients were concerned by their symptoms relative to other symptoms. The Medical Research Council dyspnoea and Eastern Cooperative Oncology Group performance status scales were completed. The majority of lung cancer patients (90%) were per...

Great talent, excellent voices-no problem for pubertal girls?Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This research on 17 girls (aged 9;9 y to 16;11 y) singing in an established choir was focused on two issues: 1) the variety in physical and vocal development using Gackle's model, and 2) the matching of vocal demands and abilities. Developmental and acoustical data on the speaking and singing voice revealed considerable variation between individual girl singers. The model was greatly applicable. However, all girls had a greater total singing range, mainly in favour of the lower tones, and 11 girls used a lower speaking fundamental frequency. A third of the girls met the vocal and developmental features of their stage a...

The contribution of supraglottic laryngeal adjustments to voice: Phonetic evidence from Arabic.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
In this study, we provide nasendoscopic observations illustrating phonetic contrasts in Arabic that require supraglottic laryngeal adjustments, and demonstrate how the laryngeal constrictor mechanism contributes to phonetic descriptions of phonation. Arabic has two pharyngeal consonants (voiceless and voiced). We show, among others, that these two consonants possess auditory features of whisperiness and creaky voice, respectively, and are always produced with supraglottic constriction similar but more marked than during whispery or creaky [i]. However, during modal [i], the epilaryngeal space is wide open. We outline a rev...

Electroglottographic analysis of valved speech following total laryngectomy.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This study shows that robust and reliable data can be obtained using electroglottography in laryngectomees with both a sustained vowel and connected speech. Using these parameters, TO speech is significantly different from normal speech and is highly variable. This methodology has enormous potential for further investigations in laryngectomees and other patients with head and neck cancer.

The difficult airway: The use of subglottic jet ventilation for laryngeal surgery.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
High-frequency subglottic jet ventilation was used in 352 cases of adults treated with suspension microlaryngoscopy. Of these, 89 had difficult airways, and these are the subject of this manuscript. All cases were managed by the senior anaesthesiologist (AP) and the senior surgeon (JR), between 2000 and 2004. There were minimal complications associated with this technique in this series. The subglottic catheter never proved impossible to insert, and was used on one occasion in a rescue mode after supraglottic jetting led to oxygen desaturation. Body habitus did not prevent use of the technique in this series. There wer...

TKK Aparat: An environment for voice inverse filtering and parameterization.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The study of the glottal flow, the acoustic excitation for voiced speech, provides insight into the voice signal, which is of potential benefit in many disciplines. One common method for estimating the glottal flow is inverse filtering, in which the effects of the vocal tract and the lip radiation are removed from a microphone signal. This paper presents a new inverse filtering and parameterization software package, which is available under an open-source licence. It provides a user-friendly graphical interface for rapid inverse filtering and parameterization, and the algorithms and parameters can be easily re-used in ...

Communicative satisfaction of male-to-female transsexuals.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The aim of this qualitative study was to gain an understanding of the way male-to-female transsexuals perceived their communication and their satisfaction with it in different aspects of their lives. Three focus groups were conducted for the purposes of this study, each consisting of four participants. The transcribed dialogues of the groups were analysed using a grounded theory approach to find the common underlying themes. These then formed the basis of the five major categories that identified key themes relating to transsexuals' communicative satisfaction: communicative situations, emotions, groups of people, other...
