The objective is for the student to acquire basic competences in the analysis of voice, speech and hearing. Competences cannot be listened to, take notes and memorize. Active learning is required from the student. 

1.- DIRECTED LEARNING

Full group classes (25 sessions,1.5 h each):

  • Each session starts with time to solve questions resulting from previous autonomous studying. Alternatively, to discuss a question posed by the instructor to prepare the class.
  • Then, the instructor presents new information, which may include practical demos and also active participation by the students (which may give samples of their own voice or speech for in-class analysis).
  • Team discussion and identification of doubts and conclusions (through peer-learning, a collaborative, horizontal learning strategy). General discussion.
  • At the end of most sessions a short test to evaluate proper understanding will be carried out. Most of them will be unmarked self-evaluation, although on occasions the test may be part of evaluation evidence EV1. 

Split group classes (6 sessions, 2 h each).

Essential part of competence-based learning. Laboratory practices, in teams of 2. Analysis of human voice, vocal qualities (efficiency items and dysphonic alterations) with the reference analysis software Praat. Analysis of acoustic cues of speech sounds, both canonical, altered and compensations.

Practices must be repeated at home, as part of individual autonomous work (Studying block).

Seminars, full group (1 session, 1,5 h).

(1) Helen Rowson, voice coach

 

2.- SUPERVISEDLEARNING

Question based learning proposed by the instructor either during a class or as previous preparation.

Field work. Team research work. Each team chooses a topic of interest that must be approved by the instructor. The assignment puts at work all the competences in the course, and involves collaborative learning and social learning. This is evalation evidence EV3.

Tutorials. Students are encouraged to request tutorials to solve doubts individually, identify weaknesses or to ask for guidance. Tutorials may be formulated either through Moodle classroom messaging or face-to-face (Biophysics Unit, School of Medicine). For face-to-face tutorials please send a Moodle message to get an appointment.

 

3.- AUTONOMOUS LEARNING

Weakly work. Essential part to properly progress. Includes:

(1) Studying class materials (notes, videos, demos...), complemented with search of informations, either books or reliable (academic) online resources. This is the basis to pose questions at the onset of each class session.

(2) Solving the questions proposed by the instructor.

(3) Free experimenting with one's own voice and speech with Praat analysis software. 

 

4.- OTHER

Additional materials such as videos or links of interest, will be uploaded at the Moodle Classroom. Students are also free to upload materials or to ask questions to be investigated and discussed by the group.

Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

1. CONTINUOUS EVALUATION

Evaluation activities

After the practical lessons and the different EV1 tests, the correct answers will be discussed by the instructor and doubts will be addressed. The objective is that evaluation is part of the learning process.

Evidence 1 (EV1) - Short tests. Can take place anytime from week 2 during the two assessment periods. Short, written, individual or team tests. Some face-to-face, some online. The final mark for EV1 is the mean of the EV1 tests that the student took multiplied by the ratio of the number of tests that the student took divided by the total number of tests carried out.

The tests can be of two types:

(I) Some of the tests at the end of the class for auto-evaluation of understanding will be part of EV1 without previous notice (single response test, errors penalize -0,25 points).

(II) Some of the autonomous learning exercises proposed by the instructor will be part of EV1.

Evidence 2 (EV2) - Evaluation of practical competences (second assessment period). Individual, written, face-to-face test about analysis of voice, speech and hearing from audio files (errors penalize -0,25 points). Students may bring all sorts of information, including their results from lab classes and books (but no Internet or previous tests).

Evidence 3 (EV3) - Field work (second assessment period). Team research work, written report, submitted to the Moodle classroom. Described in the Methodology section. Integrated evaluation of all competences in the course. If considered necessary, control mechanisms will be applied to measure the degree of involvement of each student in the work, which will have an impact on the mark.

Evidence 4 (EV4) - Integrated final evaluation (second assessment period). Weeks 17 or 18, to be determined by the School of Psychology.  Individual, written, face-to-face single response test (errors penalize -0,25 points).No access to external information sources.

Exceptional contributions may contribute 1 extra point to the final mark. 

Definition of passed course. The following two conditions must be met. (I) To individually pass evidences EV2, 3 and 4 (equal or greater than 5.0) and to reach a final mark (including EV1) equal or greater than 5.0.

According to article 266 of the UAB Academic Regulations (Assessment Results): “6. Once the subject has been passed, it cannot be subject to a new assessment.”

Definition of non-evaluable student. A student will be considered non-evaluable when they participated in evidences accounting for less than 40 % of the total mark, independently of the mark they got.

Referral exams (EV2, EV3 and/or EV4). Referral tests will take place during the examination period. To pass the referral exam a mark equal or greater than 5.0 is needed. The mark of the evidence will be that obtained at the referral exam.

Synthesis exam.  No unique final synthesis test for students who enrole for the second time or more is anticipated.

Misconduct. According to UAB rulings, if a student undergoes unethical behavior, such as cheating in an exam or plagiarising a work, the mark for that evidence will be 0. In case of reincidence the student will get a 0 mark for the whole course. The professor responsible for the course will communicate the misconduct to theCoordinatorof the SLP Degree.

2. SINGLE EVALUATION

Single evaluation is requested electronically (e-form) in the specific period (more information on the Faculty website).

It will take place on the day of the last exam of Acoustic physics and audiology during the second evaluation period. It will consist of four parts:

Evidence 1 (EV1) - Oral evaluation. Questions will be asked about any of the autonomous learning exercises proposed throughout the term.

Evidence 3 (EV3) - Field work. Individual, written report. It is described in the section of formative activities. It is a final integrated evaluation of the set of theoretical and practical competences of the subject, through a written report in the format of a scientific research work and the recorded samples.

And of the evidences EV2 and EV4 which are described in the continuous evaluation.

Definition of passed subject. To fulfill the following two conditions: to have passed individually the evidences EV2, EV3 and EV4 and to obtain an overall grade (including that of EV1) equal or higher than 5.0.

According to article 266 of the UAB Academic Regulations (Assessment Results): “6. Once the subject has been passed,it cannot be subject to a new assessment.”

Definition of non-assessable student. According to University regulations, "any student who has submitted learning evidences with aweight of less than 40% of the grade, regardless of the grade obtained,is considered not evaluable."

Referral exams (EV2, EV3 and/or EV4). It will take place during the period of recoveries and ona single day, coinciding with the recovery of EV2 of the continuous evaluation. The evidence is recovered with a grade equalto or higher than5.0. The mark of the referral test will be the one obtained.

Misconduct. According to UAB rulings, if a student undergoes unethical behavior, such as cheating in an exam or plagiarising a work, the mark for that evidence will be 0. In case of reincidence the student will get a 0 mark for the whole course. The professor responsible for the course will communicate the misconduct to the Coordinator of the SLP Degree.

4.2. Use of AI

For this subject, the use of Artificial Intelligence (AI) technologies is only allowed for EV-1 and EV-3 exclusively in support tasks, such as bibliographic or information searches, text correction or translations. The student must clearly identify which parts have been generated with this technology, specify the tools used and include a critical reflection on how these have influenced the process and the final result of the activities. The lack of transparency in the use of AI in these assessable activities will be considered a lack of academic honesty and may lead to a partial or total penalty in the grade of the activity, or greater sanctions in serious cases. In the case of EV1 of the single assessment, the use of AI can be made during the preparation of the exercises, not during the oral presentation.

Software

PRAAT program.

Praat (Dutch for "Speaking") is the program used in the practices and also the main tool for voice and speech analysis in fieldwork. In addition, it will serve to explore your own voice and speech (or that of others) as a result of the exercises proposed in class.

The Praat program is the international gold standard for voice and speech analysis. It was created by Paul Boersma and David Weenink of the Department of Phonetic Sciences at the University of Amsterdam, who distribute it free of charge. It is constantly evolving, so it incorporates new options following requests made to them from the academic and professional world, so it is convenient to update it every year.

The Praat has immense potential, which can serve you beyond this subject, in other subjects of the Degree and, if you choose these specialties, in your professional practice as speech and/or speech speech therapists.

There is a version for Windows, Mac, Linux ...
