“…Past research has shown no consistent direction in the change of F0 in the post-operative voices of patients with vocal paralysis [39] or any significant change in the speaking F0 for post-treatment voices showing improvement in voice quality [40]. Compared to normal voice, a lower F0 has been associated with edema [24], contact ulcers [41], and acute laryngitis [42] but not with nodules or polyps [41].…”

Aims: This study examined the viability of using iPhone recordings for acoustic measurements of voice quality. Methods: Acoustic measures were compared between voice signals simultaneously recorded from 11 normal speakers (6 females and 5 males) through an iPhone (model A1303, Apple, USA) and a comparison recording system. Comparisons were also conducted between the pre- and post-operative voices recorded from 10 voice patients (4 females and 6 males) through the iPhone.Participants aged between 27 and 79 years. Results: Measures from iPhone and comparison signals were found to be highly correlated. Findings of the effects of vowel type on the selected measures were consistent between the two recording systems and congruent with previous findings. Analysis of the patient data revealed that a selection of acoustic measures, such as vowel space area and voice perturbation measures, consistently demonstrated a positive change following phonosurgery. Conclusion: The present findings indicated that the iPhone device tested was useful for tracking voice changes for clinical management. Preliminary findings regarding factors such as gender and type of pathology suggest that intra-subject, instead of norm-referenced, comparisons of acoustic measures would be more useful in monitoring the progression of a voice disorder or tracking the treatment effect.

Efficacy of intensive voice therapy for patients with vocal fold nodules

The primary aetiologic factor for vocal fold nodules has been proposed to be cumulative perpendicular impact stress between the vocal folds over time, which increases with voice use (Titze, 1994). Many people with vocal fold nodules work in high vocal demand occupations, therefore, it is essential that they recover vocal function so that their ability to perform their jobs is not compromised (Karkos & McCormick, 2009). A number of studies have reported positive improvements in vocal fold nodules following various types of behavioural voice therapy, and as such, voice therapy is recommended as a first-line treatment .The majority of the intervention studies for patients with vocal fold nodules have examined treatment outcomes following traditional voice therapy models, typically delivered once a week over a period of multiple weeks. To date, no studies have systematically examined the impact of using an intensive, massed practice therapy approach. In that the rehabilitation process for vocal fold nodules requires the learning, maintenance and transfer of new behaviours, it is possible that a more condensed voice therapy protocol may yield equal or even greater benefit. Therefore, the primary aim of this thesis was to explore the efficacy of intensive voice therapy (eight sessions within 3 weeks) as compared with traditional voice therapy (one session per week for 8 weeks).Both the short and long term effects of the different treatments on perceptual, acoustic, and physiological outcomes were examined.Although it has been established that voice therapy is often effective, in many caseloads, rates of therapy completion are poor and this creates a challenge for clinicians (Portone-Maira, Wise, Johns, & Hapner, 2011). Traditional, face-to-face (FTF) voice therapy has shown dropout rates as high as 65% (Hapner, Portone-Maira, & Johns, 2009). Various factors contributing to nonattendance include travel time, inflexible work conditions, and inability to access due to physical barriers. Non-attendance not only affects treatment success, but also results in unnecessary extensions to treatment, and repeated examinations without sufficient behavioural change to effect improvement. Ultimately, there may be a loss of revenue or even employment if patients are unable to meet the vocal requirements of their occupations (Portone, et al., 2008;Portone-Maira et al., 2011). Consequently, there is a need to explore ways to help maximise attendance and ultimately enhance outcomes for people with vocal fold nodules. To this end, the secondary aim of this thesis iii was to examine the feasibility and outcomes of delivering intensive voice therapy via telepractice, as an alternative service delivery model for patients with vocal fold nodules.To address aim one, 53 female patients (56% professional voice users) with bilateral vocal fold nodules were recruited. Participants were matched in pairs according to their age, occupation, and severity of dysphonia and assigned to either of two treatment groups: traditional therapy of eigh...
