The present paper aims at establishing a minimum assessment protocol to estimate the prevalence of communication disorders, their severity and the correlation between identified communication disorders and oral communication activities among students.

Material and Methods:

A questionnaire was built using assessments published in current literature, which consists of 14 sections.

The first section gathers demographic information such as age, gender, and level of education as well as history of speech therapy services (e.g. “do you consult a speech therapist?”).

The second section asks about the ability to communicate verbally in public in social situations and the possible causes that impact a student’s ability to communicate effectively.

The third section deals with the attitudes of the student before, during and after communicating, specifically focusing on questions related to stuttering.

The proposed assessment also identified the severity of stuttering as well as any secondary behaviours associated with stuttering (e.g. eye blinking, tics, face spasms, etc.).

Sections 4 through 13 are concerned with questions related to communication disorders such as: articulation disorders, language delays, dysphasia, swallowing disorders, hearing loss, cleft lip or palate, aphasia, attention disorders, dyslexia, and dysphonia.

The last section deals with acoustic analysis, using Praat Software, where a recording of the sustained vowel /a/ is performed by each participant in order to have an overview of the following acoustic parameters: pitch, harmonics to noise ratio, shimmer and jitter.

Participants included in this study were between 18 and 22 years of age who were in their 1st or 2nd year of department of science of the Ben M’Sik College -University Hassan II Mohammedia.


The questionnaire was completed by 170 students, which insures a confidence interval of 4 and confidence level of 95%.

Among the sample, 58% of students are male, and 42% are female.

The studied sample demonstrated that 75% of the students do not feel comfortable when engaging in verbal communication in social situation, which was highly correlated with stuttering.

Lack of self-confidence, stage fright, lack of experience, shyness and the presence of an important group are 80% of the causes students do not feel at ease when publicly speaking in front of an unfamiliar group.

The study revealed that 20% of students had fluency disorders, 15% had articulation disorders, 21% had swallowing disorders, 19% had dysphasia, 1% of the students had hearing loss, 14% had attention disorders, 10% had dyslexia, and 6% had dysphonia.

The major finding of the present paper was that 54% of the students studied were identified as having a language delay.

Subjective assessments of the communication disorders are complemented with objective assessments based on acoustic analysis of the sustained vowel /a/ recorded from the studied sample.

Based on the conducted research, we found that communication disorders impact the oral communication activities with a percent of 27%.

By using objective assessments to analyse the threshold of acoustic parameters such as jitter, shimmer, mean harmonic to noise ratio and minimum and maximum pitch, we can determine the presence or absence of a voice disorder.


The present paper proposes a ready-to-use assessment of communication disorders.

The proposed model can be used with large groups as well as with individual students.

Subjective assessment used in combination with objective assessments allow for a complete evaluation of communication disorders.

Keywords: Assessment of communication disorders, Acoustic analysis, Communication disorders, Oral communication in public, Stuttering assessment, Voice disorders.

"Open access will revolutionize 21st century knowledge work and accelerate the diffusion of ideas and evidence that support just in time learning and the evolution of thinking in a number of disciplines."

Daniel Pesut
(Indiana University School of Nursing, USA)

"It is important that students and researchers from all over the world can have easy access to relevant, high-standard and timely scientific information. This is exactly what Open Access Journals provide and this is the reason why I support this endeavor."

Jacques Descotes
(Centre Antipoison-Centre de Pharmacovigilance, France)

"Publishing research articles is the key for future scientific progress. Open Access publishing is therefore of utmost importance for wider dissemination of information, and will help serving the best interest of the scientific community."

Patrice Talaga
(UCB S.A., Belgium)

"Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information."

Jeffrey M. Weinberg
(St. Luke's-Roosevelt Hospital Center, USA)

"Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals."

Debomoy K. Lahiri
(Indiana University School of Medicine, USA)

"Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities."

Robert Looney
(Naval Postgraduate School, USA)

"Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets."

Richard Reithinger
(Westat, USA)

"Not only do open access journals greatly improve the access to high quality information for scientists in the developing world, it also provides extra exposure for our papers."

J. Ferwerda
(University of Oxford, UK)

"Open Access 'Chemistry' Journals allow the dissemination of knowledge at your finger tips without paying for the scientific content."

Sean L. Kitson
(Almac Sciences, Northern Ireland)

"In principle, all scientific journals should have open access, as should be science itself. Open access journals are very helpful for students, researchers and the general public including people from institutions which do not have library or cannot afford to subscribe scientific journals. The articles are high standard and cover a wide area."

Hubert Wolterbeek
(Delft University of Technology, The Netherlands)

"Open access journals are very useful for all scientists as they can have quick information in the different fields of science."

Philippe Hernigou
(Paris University, France)

"There are many scientists who can not afford the rather expensive subscriptions to scientific journals. Open access journals offer a good alternative for free access to good quality scientific information."

Fidel Toldrá
(Instituto de Agroquimica y Tecnologia de Alimentos, Spain)

"Open access journals have become a fundamental tool for students, researchers, patients and the general public. Many people from institutions which do not have library or cannot afford to subscribe scientific journals benefit of them on a daily basis. The articles are among the best and cover most scientific areas."

M. Bendandi
(University Clinic of Navarre, Spain)

"These journals provide researchers with a platform for rapid, open access scientific communication. The articles are of high quality and broad scope."

Peter Chiba
(University of Vienna, Austria)

"Open access journals are probably one of the most important contributions to promote and diffuse science worldwide."

Jaime Sampaio
(University of Trás-os-Montes e Alto Douro, Portugal)

"Open access journals make up a new and rather revolutionary way to scientific publication. This option opens several quite interesting possibilities to disseminate openly and freely new knowledge and even to facilitate interpersonal communication among scientists."

Eduardo A. Castro
