“…Previous study conducted on Mandarin Chinese speakers exhibited that the users of certain drugs (i.e., heroin, ketamine, and methamphetamine) showed smaller F0 standard deviation, reduced loudness, and cepstral peak prominence, as well as higher H1–A3, longer unvoiced segments, and fewer voiced segments per second [ 12 ]. Therefore, some scholars have proposed that these differences indicate that the acoustic characteristics of drug users deviate from the norm [ 12 , 13 ].…”

This study aims to investigate the effect of detoxification on acoustic features of Mandarin speech. Speech recordings were collected from 66 male abstinent heroin users with different durations of drug detoxification, specifically early abstinent users with a detoxification duration of less than 2 years, sustained abstinent users with 2 years of detoxification, and long-term abstinent users with a detoxification duration of more than 2 years. The results of the acoustic analyses showed that early abstinent users exhibited lower loudness, relative energies of F1, F2, and F3, higher H1–A3, and fewer loudness peaks per second, as well as a longer average duration of unvoiced segments, compared to the sustained and long-term abstinent users. The findings suggest that detoxification may lead to a rehabilitation process in the speech production of abstinent heroin users (e.g., less vocal hoarseness). This study not only provides valuable insights into the effect of detoxification on speech production but also provides a theoretical basis for the speech rehabilitation and detoxification treatment of heroin users.

“…The cortico-basal ganglia (CBG) circuitry is known to be involved in many cognitive functions such as motivation, reward-based learning and the execution of motor functions including speech and vocalization ( Doupe and Kuhl, 1999 ; Kao et al, 2005 ; Van Lancker Sidtis et al, 2006 ; Ziegler and Ackermann, 2017 ). Although speech deficits such as slurring or stuttering are amongst some of the common symptoms of drug addiction ( Wasserman and Yahr, 1980 ), changes in the acoustic properties of speech such as a decrease in pitch, and increased hoarseness ( Mirkov and Mitrović, 2019 ) have not been studied extensively. Furthermore, despite the fact that opioid receptors are expressed in many cortical areas ( Bodnar, 2018 ; van Steenbergen et al, 2019 ) which project directly to the basal ganglia, the effects of opioid neuromodulation in the context of vocalization has not been explored in detail.…”

Blocking Opioid Receptors in a Songbird Cortical Region Modulates the Acoustic Features and Levels of Female-Directed Singing

et al. 2020

The organization of the anterior forebrain pathway (AFP) of songbirds important for context-dependent singing is similar to that of cortical basal ganglia loops (CBG) in mammals, which underlie motor behaviors including vocalization. Since different components of the AFP express high levels of µ-opioid receptors (µ-ORs) as do CBG loops, songbirds act as model systems to study the role of opioid modulation on vocalization and the motivation to sing. The AFP in songbirds includes the cortical/pallial region LMAN (lateral magnocellular nucleus of the anterior nidopallium) which projects to Area X, a nucleus of the avian basal ganglia. In the present study, microdialysis was used to infuse different doses of the opioid antagonist naloxone in LMAN of adult male zebra finches. Whereas all doses of naloxone led to significant decreases in the number of FD (female-directed) songs, only 100 and 200 ng/ml of naloxone affected their acoustic properties. The decrease in FD song was not accompanied by changes in levels of attention toward females or those of neurotransmitters (dopamine, glutamate, and GABA) in LMAN. An earlier study had shown that similar manipulations in Area X did not lead to alterations in the number of FD songs but had significantly greater effects on their acoustic properties. Taken together, our results suggest that there are reciprocal effects of OR modulation on cortical and basal ganglia components of the AFP in songbirds.

“…This system is based on the assessment of the roughness (R) and the breathiness (B) of a voice on a 0 to 3 scale by a clinician with 0 indicating no impairment and 3 indicating maximum roughness/breathiness. Subsequently the hoarseness H (RBH-H) is determined as the maximum of the first two values R and B and is in the following used to differentiate between groups [22]- [25].…”

Background: Various voice assessment tools, such as questionnaires and aerodynamic voice characteristics, can be used to assess vocal function of individuals. However, not much is known about the best combinations of these parameters in identification of functional dysphonia in clinical settings. Methods: This study investigated six scores from clinically commonly used questionnaires and seven acoustic parameters. 514 females and 277 males were analyzed. The subjects were divided into three groups: one healthy group (N 01 ) (49 females, 50 males) and two disordered groups with perceptually hoarse (FD 23 ) (220 females, 96 males) and perceptually not hoarse (FD 01 ) (245 females, 131 males) sounding voices. A tree stumps Adaboost approach was applied to find the subset of parameters that best separates the groups. Subsequently, it was determined if this parameter subset reflects treatment outcome for 120 female and 51 male patients by pairwise pre-and post-treatment comparisons of parameters. Results: The questionnaire ''Voice-relatedquality-of-Life'' and three objective parameters (''maximum fundamental frequency'', ''maximum Intensity'' and ''Jitter Percent'') were sufficient to separate the groups (accuracy ranging from 0.690 (FD 01 vs. FD 23 , females) to 0.961 (N 01 vs. FD 23 , females)). Our study suggests that a reduced parameter subset (4 out of 13) is sufficient to separate these three groups. All parameters reflected treatment outcome for patients with hoarse voices, Voice-related-quality-of-Life showed improvement for the not hoarse group (FD 01 ). Conclusion: Results show that single parameters are insufficient to separate voice disorders but a set of several well-chosen parameters is. These findings will help to optimize and reduce clinical assessment time.

Vocal assessment of addicts on methadone therapy via the RBH scale and objective acoustic parameters

Abstract: A statistically significant correlation was found between the two subjective vocal assessments, voice clarity and pitch, and Roughness-Breathiness-Hoarseness scale, and the parameters of the objective acoustic vocal assessment.
