Prosody not only signals the speaker’s cognitive states but can also imitate various concepts. However, previous studies on the latter, the iconic function of prosody, have mostly analyzed novel words and nonlinguistic vocalizations. To fill this gap in the literature, the current study has examined the iconic potential of the prosodic features of existing Japanese imitative words known as ideophones. In Experiment 1, female Japanese speakers pronounced 20 sentences containing ideophones in infant-directed speech. They used a higher f0 to express faster and more pleasant movements. Similar iconic associations were observed in Experiment 2, in which Japanese speakers chose the best-matching pitch–intensity–duration combination for each of the ideophones. In Experiment 3, Japanese speakers chose the best-matching voice quality – creaky voice, falsetto, harsh voice or whisper – for the ideophones. Falsetto was preferred for a light object’s fast motion, harsh voice for violent motion and whisper for quiet motion. Based on these results, we entertain the possibility that the iconic prosody of ideophones provides a missing link in the evolutionary theory of language that began with iconic vocalizations. Ideophones with varying degrees of iconic prosody can be considered to be located between nonlinguistic vocalizations and arbitrary words in this evolutionary path.
Tima has a typologically unusual 12-vowel advanced tongue root (ATR) harmony system, contrasting six [+ATR] vowels /i e ɨ ʌ o u/ with six [−ATR] vowels /ɪ ɛ ɘ a ɔ ʊ/. This harmony system provides a test case for generalisations about ATR systems: for example, that [−ATR] is less compatible with higher vowels; that [+ATR] is less compatible with lower vowels and that central vowels are incompatible with [ATR] systems. After showing that all vowels participate fully in ATR harmony, this article presents an acoustic study of the Tima ATR contrast. We show that /ʌ/, the [+ATR] counterpart of /a/, patterns as a mid vowel, and that duration and voice quality differences characterise Tima’s crowded vowel inventory. Though F1 is the primary individual correlate of the ATR contrast, as is true cross-linguistically, a number of measures support voice quality differences as well, as predicted by the Laryngeal Articulator Model account of ATR systems.
To investigate the effect of heated-cigarette smoking on voice.
Methods
Participants completed a survey including three sections: section-1 comprised demographic data, section-2 comprised visual analogue scale grading of voice changes and fatigue and section-3 consisted of the voice handicap index-10.
Results
Two hundred and eighty-two participants filled the survey. Heated-cigarette smokers had a significantly higher mean voice handicap index-10 score compared to non-smokers (p < 0.05). The difference in voice handicap index-10 scores between heated- and combustion-cigarette smokers was not statistically significant. The number of abnormal voice handicap index-10 scores was higher in heated-cigarette smokers compared to non-smokers (p < 0.05) and significantly higher in combustion-cigarette and dual heated- and combustion-cigarette smokers compared to the other 2 groups (p < 0.05). Non-smokers had significantly lower grades of voice changes and fatigue when compared to combustion and dual heated- and combustion-cigarette smokers (p < 0.05).
Conclusion
Smokers of heated cigarettes have a significantly higher mean voice handicap index-10 score compared to non-smokers and higher grade of voice changes and fatigue.
Suprasegmentals are phonetic elements that are not restricted to individual segments, but whose influence extends across a number of segments. What is phonetically the same type of suprasegmental may play a role at a very different place in the grammatical structure of a given language. One type is prominence, involving extra loudness and duration of the segments that are affected. In English, prominence is primarily grammatical stress playing a role in word pronunciation, but also emphasis, playing a role in the structure of a phrase or sentence. In English, an unstressed syllable contains a reduced vowel, normally realized as schwa. Another type of suprasegment involves variation in fundamental frequency. If this occurs at the level of the word (especially where words are restricted to a single syllable), the phenomenon is tone. Where F0 variation plays a role in the grammatical structure of the phrase or sentence, the phenomenon is intonation. Articulatory set (setting) is considered as a suprasegmental.
This paper promotes a sophisticated treatment of gender in variationism through a large-scale quantitative analysis of creak, a nonmodal voice quality stereotypically associated with women in US English. An analysis of our gender-diverse corpus, including cisgender, transgender, and nonbinary individuals, finds that gender does not predict variation; all gender groups produce high rates of creak. However, gender does interact with style: all speakers use more creak in interview speech compared with read speech, but some groups style-shift more than others, suggesting that gender remains a relevant factor in capturing how creak is deployed as a resource in social practice. We use this analysis to advocate for a move beyond the gender binary in quantitative descriptions of sociolinguistic variables and call for the greater inclusion of trans+ individuals in sociolinguistics.
To compare the effectiveness of radiofrequency Coblation assisted excision and cold steel excision in the treatment of idiopathic vocal process granulomas.
Methods
A retrospective study was performed of patients with idiopathic vocal process granulomas who underwent radiofrequency Coblation excision or cold steel excision between January 2013 and January 2020. The recurrence rate was compared among the two groups at six months post-operatively.
Results
Of the 47 patients with vocal process granulomas, 28 were in the cold steel excision (control) group and 19 were in the Coblation-assisted group. The recurrence rate in the control group was significantly higher than that in the Coblation-assisted group (60.7 per cent vs 5.3 per cent; p < 0.001). In addition, the voice recovery of the Coblation-assisted group was significantly better than that of the control group; vocal quality recovered one month after surgery in the Coblation-assisted group.
Conclusion
Radiofrequency Coblation should be considered the optimal method when approaching idiopathic vocal process granulomas surgically.
In this paper, we show that Icelandic uses the phonetic parameters of speaking rate, duration and voice quality (VQ) to distinguish between information-seeking questions (ISQs) and rhetorical questions (RQs). Specifically, durations are longer (speaking rate is slower) and nonmodal VQs are used more in RQs than in ISQs. Our findings for temporal parameters fit in with previous studies on the prosody of RQs in various languages. With respect to VQ, Icelandic differs, for example, from German and English in the location of breathy voice in the utterance (utterance-initial in German and English, utterance-final in Icelandic). We interpret the utterance-final position of breathiness in Icelandic RQs as a potential compensating strategy for the lack of phonological cues, i.e. boundary tones.
Platelet-rich plasma has gained interest over the two last decades, mainly because of its role in regenerative medicine. This work aimed to assess the role of intra-operative local application of platelet-rich plasma gel in the improvement of quality of voice after microlaryngeal surgery.
Method
This was a prospective comparative study that included 40 patients undergoing microlaryngeal surgery for benign vocal fold lesions. There were two groups divided equally into study group A and control group B. The assessment of voice was performed by videostroboscopy and acoustic analysis pre-operatively and at two weeks and one and three months post-operatively.
Results
The data demonstrated that all the stroboscopic and acoustic parameters showed significant improvement in both groups. Group A showed significant improvement regarding acoustic parameters at the third post-operative follow up when compared with group B.
Conclusion
Platelet-rich plasma has a beneficial effect on voice quality following microlaryngeal surgery based in particular on acoustic parameters.
This chapter examines voice quality as the long-term, relatively constant or habitually recurring phonetic characteristics of an individual’s speech. The identification of voice quality settings relates the auditory/acoustic components of the voice quality strand of an individual’s accent (i.e. habitual manner of speaking) to the articulatory postures or movements that shape speech sound quality over the long term. An essential generator of long-term quality is the larynx, producing sustained vibrations and laryngeal articulatory resonances that interact with vowel quality and tonal quality. Various instrumental phonetic procedures have been developed to observe postural settings of the parts of the vocal tract. The images from these experimental observations have been incorporated into instructional tools for teaching and learning about voice quality settings and the movements of the laryngeal articulatory mechanism in particular.
This study evaluated the correlation between patient and clinician subjective voice analysis in a group of patients suffering from muscular tension dysphonia. This disease does not usually present with organic lesions, and voice analysis is crucial to evaluate it.
Methods
A retrospective study with 75 patients was performed. Correlation between grade, roughness, breathiness, asthenia and strain scale and voice handicap index-10 was analysed. Any possible influence of the type of muscular tension dysphonia on these two scales was studied.
Results
There are only a few studies that correlate voice handicap index-10 and the grade, roughness, breathiness, asthenia and strain scale; however, none of them are specific for patients suffering from muscular tension dysphonia. A moderate correlation (r = 0.56) was found. No influence of muscular tension dysphonia type on voice handicap index-10 score was found, but muscular tension dysphonia type 4 had worse grade, roughness, breathiness, asthenia and strain scale scores than other muscular tension dysphonia types. This could be explained if muscular tension dysphonia type 4 is considered to be the most severe form of this disease.
Conclusion
The use of assessment scales based on the opinion of both the clinician and patient must be considered as complementary clinical tools in order to perform a complete assessment of dysphonia.
The term paralinguistics (from ‘alongside language’ in ancient Greek) describes sounds that carry meaning, but that are not part of the language system. Such sounds convey information to other speakers, but they are not always clear, leaving one with a sense of ‘it wasn’t what they said, but how they said it.’ To interpret the speaker’s tone, participants often rely on the context of the interaction. This chapter explores research on paralinguistic features in four categories: voice quality, prosody, conversational management, and accent. The discussion includes how affect is expressed in electronic communication. Afterwards, these concepts are connected to an intercultural communication-oriented pedagogy, with sample language teaching activities.
Transoral laser microsurgery for glottic squamous cell carcinoma is the standard of care at many institutions. Repeat transoral laser microsurgery for recurrence may avoid the need for radiotherapy and total laryngectomy. This study aimed to identify oncological and functional outcomes in a cohort of patients who had undergone repeat transoral laser microsurgery procedures.
Method
A retrospective review of prospectively collected data of patients treated with transoral laser microsurgery for carcinoma in situ or tumour stages T1 or T2 glottic cancer, from 2003 to 2018.
Results
Twenty patients were identified. Additional treatment was not needed in 45 per cent of patients. The five-year overall survival rate was 90 per cent. The disease-specific survival rate was 100 per cent. The laryngeal preservation rate was 85 per cent. There was improvement in mean Voice Handicap Index-10 scores following repeat transoral laser microsurgery treatment, when comparing the pre- and post-operative periods (mean scores = 15.5 vs 11.5, p = 0.373).
Conclusion
Repeat transoral laser microsurgery can be an oncologically safe alternative to other salvage therapies for glottic squamous cell carcinoma recurrence, without sacrificing functional outcomes.
The first description of voice quality production in forty years, this book provides a new framework for its study: The Laryngeal Articulator Model. Informed by instrumental examinations of the laryngeal articulatory mechanism, it revises our understanding of articulatory postures to explain the actions, vibrations and resonances generated in the epilarynx and pharynx. It focuses on the long-term auditory-articulatory component of accent in the languages of the world, explaining how voice quality relates to segmental and syllabic sounds. Phonetic illustrations of phonation types and of laryngeal and oral vocal tract articulatory postures are provided. Extensive video and audio material is available on a companion website. The book presents computational simulations, the laryngeal and voice quality foundations of infant speech acquisition, speech/voice disorders and surgeries that entail compensatory laryngeal articulator adjustment, and an exploration of the role of voice quality in sound change and of the larynx in the evolution of speech.

Recapitulates the phonetic theories of Abercrombie and Laver, introduces the Laryngeal Articulator Model of the vocal tract, and refers to the iPA Phonetics app as a tool for accessing auditory samples of voice qualities and visual images of articulations. The model supersedes the simple glottal-phonation paradigm of the larynx, replacing it with the ‘two-part vocal tract,’ containing a complex articulator in the lower vocal tract paralleling the tongue in the oral vocal tract.
Transoral laser microsurgery is an increasingly common treatment modality for glottic carcinoma. This study aimed to determine the effect of age, gender, stage and time on voice-related quality of life using the Voice Handicap Index-10.
Methods
Primary early glottic carcinoma patients treated with transoral laser microsurgery were included in the study. Self-reported Voice Handicap Index testing was completed pre-operatively, three months post-operatively, and yearly at follow-up appointments.
Results
Voice Handicap Index improvement was found to be dependent on age and tumour stage, while no significant differences were found in Voice Handicap Index for gender. Voice Handicap Index score was significantly improved at 12 months and 24 months. Time versus Voice Handicap Index modelling revealed a preference for non-linear over linear regression.
Conclusion
Age and stage are important factors, as younger patients with more advanced tumours show greater voice improvement post-operatively. Patient's Voice Handicap Index is predicted to have 95 per cent of maximal improvement by 5.5 months post-operatively.
Researchers evaluating voice disorder interventions currently have a plethora of voice outcome measurement tools from which to choose. Faced with such a wide choice, it would be beneficial to establish a clear rationale to guide selection. This article reviews the published literature on the three main areas of voice outcome assessment: (1) perceptual rating of voice quality, (2) acoustic measurement of the speech signal and (3) patient self-reporting of voice problems. We analysed the published reliability, validity, sensitivity to change and utility of the common outcome measurement tools in each area. From the data, we suggest that routine voice outcome measurement should include (1) an expert rating of voice quality (using the Grade-Roughness-Breathiness-Asthenia-Strain rating scale) and (2) a short self-reporting tool (either the Vocal Performance Questionnaire or the Vocal Handicap Index 10). These measures have high validity, the best reported reliability to date, good sensitivity to change data and excellent utility ratings. However, their application and administration require attention to detail. Acoustic measurement has arguable validity and poor reliability data at the present time. Other areas of voice outcome measurement (e.g. stroboscopy and aerodynamic phonatory measurements) require similarly detailed research and analysis.
Methods of perceptual voice evaluation have yet to achieve satisfactory consistency; complete acceptance of a recognised clinical protocol is still some way off.
Materials and methods:
Three speech and language therapists rated the voices of 43 patients attending the problem asthma clinic of a teaching hospital, according to the grade-roughness-breathiness-asthenicity-strain (GRBAS) scale and other perceptual categories.
Results and analysis:
Use of the GRBAS scale achieved only a 64.7 per cent inter-rater reliability and a 69.6 per cent intra-rater reliability for the grade component. One rater achieved a higher degree of consistency. Improved concordance on the GRBAS scale was observed for subjects with laryngeal abnormalities. Raters failed to reach any useful level of agreement in the other categories employed, except for perceived gender.
Discussion:
These results should sound a note of caution regarding routine adoption of the GRBAS scale for characterising voice quality for clinical purposes. The importance of training and the use of perceptual anchors for reliable perceptual rating need to be further investigated.
A wide range of well validated instruments is now available to assess voice quality and voice-related quality of life, but comparative studies of the responsiveness to change of these measures are lacking. The aim of this study was to assess the responsiveness to change of a range of different measures, following voice therapy and surgery.
Design:
Longitudinal, cohort comparison study.
Setting:
Two UK voice clinics.
Participants:
One hundred and forty-four patients referred for treatment of benign voice disorders, 90 undergoing voice therapy and 54 undergoing laryngeal microsurgery.
Main outcome measures:
Three measures of self-reported voice quality (the vocal performance questionnaire, the voice handicap index and the voice symptom scale), plus the short form 36 (SF 36) general health status measure and the hospital anxiety and depression score. Perceptual, observer-rated analysis of voice quality was performed using the grade–roughness–breathiness–asthenia–strain scale. We compared the effect sizes (i.e. responsiveness to change) of the principal subscales of all measures before and after voice therapy or phonosurgery.
Results:
All three self-reported voice measures had large effect sizes following either voice therapy or surgery. Outcomes were similar in both treatment groups. The effect sizes for the observer-rated grade–roughness–breathiness–asthenia–strain scale scores were smaller, although still moderate. The roughness subscale in particular showed little change after therapy or surgery. Only small effects were observed in general health and mood measures.
Conclusion:
The results suggest that the use of a voice-specific questionnaire is essential for assessing the effectiveness of voice interventions. All three self-reported measures tested were capable of detecting change, and scores were highly correlated. On the basis of this evaluation of different measures' sensitivities to change, there is no strong evidence to favour either the vocal performance questionnaire, the voice handicap index or the voice symptom scale.
There is an increasing choice of voice outcome research tools, but good comparative data are lacking.
Objective:
To evaluate the reliability and validity of three voice-specific, self-reported scales.
Design:
Longitudinal, cohort comparison study.
Setting:
Two UK voice clinics: the Freeman Hospital, Newcastle upon Tyne, and the Glasgow Royal Infirmary.
Participants:
One hundred and eighty-one patients presenting with dysphonia.
Main outcome measures:
All patients completed the vocal performance questionnaire, the voice handicap index and the voice symptom scale. For comparison, each patient's voice was recorded and assessed perceptually using the grade–roughness–breathiness–aesthenia–strain scale. The reliability and validity of the three self-reported vocal performance measures were assessed in all subjects, while 50 completed the questionnaires again to assess repeatability.
Results:
The results of the 170 participants with completed data sets showed that all three questionnaires had high levels of internal consistency (Cronbach's alpha = 0.81–0.95) and repeatability (voice handicap index = 0.83; vocal performance questionnaire = 0.75; voice symptom scale = 0.63). Concurrent and criterion validity were also good, although, of the grade–roughness–breathiness–aesthenia–strain subscales, roughness was the least well correlated with the self-reported measures.
Conclusion:
The vocal performance questionnaire, the voice handicap index and the voice symptom scale are all reliable and valid instruments for measuring the patient-perceived impact of a voice disorder.
Rehabilitation of voice and speech after total laryngectomy has become established practice in recent years. A voice prosthesis is placed within a surgically produced fistula between the trachea and upper oesophagus and acts as a one way valve, allowing passage of pulmonary air from the trachea into the oesophagus and preventing aspiration of food and fluid from the oesophagus into the trachea. Persistent leakage through or around these prostheses is a recognized complication, the aetiology of which can vary widely, from mechanical issues with the prostheses themselves to anatomical and physiological issues associated with the reconstructed pharynx.
We report a new technique of using Dysport® in the management of intractable central leakage due to premature and forceful closure of the upper oesophageal sphincter during swallowing. This resulted in the pooling of fluids around the posterior flange of the prosthesis. This, along with the increased pressure from the muscle contraction, led to central leakage, as identified on videofluoroscopy. An injection of Dysport paralysed the upper oesophageal sphincter, preventing pooling of fluids around the prosthesis and the forcing open of the valve. The effect was to eliminate the leakage, and the patient did not require further injections over the following 22 months.
