“…A third challenge lies in direct rather than analogue evidence voice quality. Instead of working with quantitative measurements-as for example, Brody et al (1975), Holbrook et al (1974), Howard and Welch (1989), Till et al (1987), and others-this might be best achieved through the use of real-time continuous display of a voice quality-related parameter.…”

“…This means that there is no discrepancy with the goal for which it was used, since microphones are developed for acoustic waveform measurements (intensity and pitch). Microphones (and the real-time feedback on acoustical properties) seem to be effective in decreasing abusive vocal intensity (Holbrook et al, 1974;McGillivray et al, 1994), increasing hypofunctional intensity (Brody et al, 1975), increasing vocal performance (Howard & Welch, 1989;Rossiter et al, 1996) and reducing stomal noise (Till et al, 1987), but seems unable to increase overtones (Laukkanen et al, 2004).…”

“…Through analogue-to-digital conversion, the computer program digitized the analogue Visi-Pitch signal, which then could be used not only for clinical purposes but also for research purposes. Holbrook et al (1974) presented the Voice Intensity Controller. Once a laryngeal accelerometer has captivated the voice signal, it is amplified and sent to an adjustable electronic switch, which activates an oscillator switch.…”

“…Holbrook, Rolnick, and Bailey (1974) used the Vocal Intensity Controller 5 in 32 patients with hyperfunctional voice disorders, presenting vocal cord lesions and/or dysphonia related to vocal hyperfunction. In this non-experimental one-group pretest-posttest design, 27 patients completed the therapy with pre-and post-treatment laryngoscopy.…”

The purpose of this article was to systematically review the literature on the effects of biofeedback therapy in the domain of phonatory disorders and phonatory performance, using studies in peer-reviewed journals. An extensive definition of biofeedback is given and its place in voice treatment is defined. Eighteen group or case studies or reports considering the effects of electromyographic, laryngoscopic and acoustic biofeedback in dysphonic patients (hyperfunctional voice disorders, hypofunctional voice disorders, psychogenic voice disorder, laryngeal trauma, total laryngectomy, vocal cord dysfunction) and participants with normal voices are included and an analysis of procedure as well as research design and results is presented. The usefulness of biofeedback in phonatory disorders and performance was to be interpreted based on tendencies, since there is a lack of randomized controlled efficacy studies. In only 3 of 18 studies (16.7%) did biofeedback therapy fail to improve voice quality or not result in better results than other forms of therapy. Recommendations for improved methodologies are made, which include the use of acoustic voice quality parameters.

“…Commercial and research ambulatory voice monitors equipped with biofeedback capabilities use routines that provide immediate 100% feedback based on amplitude or fundamental frequency targets (Holbrook, Rolnick, & Bailey, 1974;McGillivray, Proctor-Williams, & McLister, 1994;Van Stan et al, 2014). In order to implement motor learning study designs with ambulatory voice biofeedback schedules, new capabilities were developed for a smartphonebased software application called the Voice Health Monitor (VHM; Llico et al, 2015;Mehta, Zañartu, Feng, Cheyne, & Hillman, 2012).…”

Purpose Ambulatory voice biofeedback has the potential to significantly improve voice therapy effectiveness by targeting carryover of desired behaviors outside the therapy session (i.e., retention). This study applies motor learning concepts (reduced frequency and delayed, summary feedback) that demonstrate increased retention to ambulatory voice monitoring for training nurses to talk softer during work hours. Method Forty-eight nurses with normal voices wore the Voice Health Monitor (Mehta, Zañartu, Feng, Cheyne, & Hillman, 2012) for 6 days: 3 baseline days, 1 biofeedback day, 1 short-term retention day, and 1 long-term retention day. Participants were block-randomized into 3 different biofeedback groups: 100%, 25%, and Summary. Performance was measured in terms of compliance time below a participant-specific vocal intensity threshold. Results All participants exhibited a significant increase in compliance time (Cohen's d = 4.5) during biofeedback days compared with baseline days. The Summary feedback group exhibited statistically smaller performance reduction during both short-term ( d = 1.14) and long-term ( d = 1.04) retention days compared with the 100% feedback group. Conclusions These findings suggest that modifications in feedback frequency and timing affect retention of a modified vocal behavior in daily life. Future work calls for studying the potential beneficial impact of ambulatory voice biofeedback in participants with behaviorally based voice disorders.

We found no evidence that either direct or indirect voice training or the two combined are effective in improving self-reported vocal functioning when compared to no intervention. The current practice of giving training to at-risk populations for preventing the development of voice disorders is therefore not supported by definitive evidence of effectiveness. Larger and methodologically better trials are needed with outcome measures that better reflect the aims of interventions.
