“…23 SOVTEs are methods of voice therapy that have been investigated and validated for their positive effects on vocal efficiency and vocal capacity of healthy subjects and voice patients. [24][25][26][27][28][29][30][31] Furthermore, Titze verified small vocal fold collision velocity and conserved vibrational amplitude during straw phonation through computational modeling. Smaller collision forces may play a role in tissue recovery.…”

“…The 10-minute intervention was introduced because it simulates a teaching schedule of a 60-minute lecture and 10-minute rest, and our previous research indicated that 10-minute straw phonations have the best immediate and lingering therapeutic effects without causing further fatigue. 25,34 For the straw phonation condition, subjects were instructed based on the video "Ingo Titze's Tip for Tired Voices: Grab a Straw!" produced by the National Center for Voice and Speech.…”

Objectives: Straw phonation has been investigated for its vocal warm-up effects on healthy populations and therapeutic effects on voice patients. The purpose of this article was to determine whether it is beneficial for vocal fatigue. Study Design: Prospective cohort study Methods: Twenty-five healthy participants were recruited into 1-hour vocal loading tasks followed by 10-minute vocal rest or straw phonation on 2 different days. Various parameters including phonation threshold pressure (PTP), mean airflow, closed quotient (CQ), current speaking effort level (EFFT), and laryngeal discomfort (DISC) were acquired at baseline, after vocal load, and after the intervention. Results: Increased PTP, EFFT, and DISC were observed after vocal load. Decreased PTP, EFFT, and DISC were then acquired after both vocal rest or straw phonation. More significant improvements were obtained in straw phonation when compared with vocal rest. Additionally, significantly increased mean flow and decreased CQ were obtained after straw phonation when compared to vocal rest. Conclusions: Straw phonation has the potential to adjust aerodynamics within the vocal tract leading to improved vocal efficiency, optimized vibration mode, and attenuated vocal fatigue. This study provided a promising treatment for vocal fatigue that could have wide clinical relevance to voice users with high voice demands.

“…This may indicate that acoustic parameters are not adequately sensitive to reflect the subtle conformational changes in a healthy state, while the acoustics may show improvement in pathological voice. No significant changes in acoustic parameters were observed after straw phonation in healthy participants in both of Kang et al's studies, [40,38] while reduced roughness, breathiness, and noise measurements as well as increased glottal to noise excitation ratio were observed after straw phonation in 27 dysphonic children [41]. The within-group comparison revealed that F0 was dependent on the vocal fold elongation and subglottal pressure.…”

“…Reduced PTP was obtained after a long-duration straw phonation task in 20 healthy subjects in Mills et al's study [30]. PTP was also found to have decreased significantly in 26 healthy subjects after 10 minutes of straw phonation in Kang et al's study [15]. Results for PTP and PTF revealed that less input energy was needed to produce a desired voice when phonation through a straw.…”

“…Recent studies have validated straw phonation results in a reduced PTP and PTF [5,15], which provide valuable insights into the effort required to initiate vocal fold oscillation, however, these parameters do not offer information on the aerodynamic characteristics of chaotic voice production and normal phonatory range. Phonation instability pressure/flow (PIP/PIF), the subglottal pressure/flow at which vocal fold vibration becomes irregular, are valuable in assessing onset of chaotic voice.…”

Purpose-This study investigated the effects of straw phonation therapy on the aerodynamic and acoustic parameters of the vocal folds at different levels of elongation and subglottal pressure. Methods-20 excised canine larynges were used in both experimental (straw phonation therapy simulation) and control conditions. Aerodynamic parameters, including phonation threshold pressure (PTP), phonation instability pressure (PIP), phonation pressure range (PPR), phonation threshold flow (PTF), phonation instability flow (PIF), phonation flow range (PFR), were obtained at different level of vocal fold elongation (0%, 10%, 20%). Acoustic parameters, including fundamental frequency (F0), jitter, shimmer, signal noise ratio (SNR) were detected at different levels of vocal fold elongation (0%, 10%, 20%) and subglottal pressure (15 cmH 2 O, 20 cmH 2 O, 25 cmH 2 O). Results-Significant decreases in PTP and PTF and significant increases in PIP, PIF, PPR, PFR were occurred in experimental condition at all levels of elongation when compared with control condition. However, no significant changes of acoustic parameters were obtained between conditions at all levels. Conclusion-At different levels of vocal fold elongation, straw phonation not only lowered the onset of normal voice, but also elevated the onset of chaotic voice, indicating a better voice economy and voice control. Moreover, the improved phonatory range demonstrated straw phonation had the potential to prevent voice users who have high voice demand from voice fatigue and vocal damage.
