Entrance requirements

Some background in Phonetics and Speech Science (recommended).

Course description

The decade-long search for invariance in units of speech and their representations has revealed that invariance is elusive and variability is pervasive. However, variability is not random but, for the most part, lawful. One of the most important factors affecting the variability of speech is coarticulation. The term covers a range of contextual effects on a target unit of speech, including the immediate segmental context, the syllable structure, the local prosodic structure, and other, higher-level structural effects. In this seminar, papers addressing the detection, description, modeling, and theoretical explanation of coarticulatory effects will be presented and discussed, with respect to both their phonological and phonetic assumptions and their implementation and application to speech technology systems (e.g., speech synthesis, speech recognition). Participants will read, present, and discuss selected papers.

Course credits

7 CP (presentation and paper) or 4 CP (presentation only).
Active participation on a regular basis required.

Requirements

Participation: You are expected to be physically present throughout the seminar and take part in the discussion.
You may miss maximally one class without formal consequences. Please send me an email message in this case, just saying that you will not take part, no explanation required. In case you cannot make it a second or third time, you have to write and submit a summary of the papers to be read (minimum one page per paper).

Reading: For each class, you are required to read one or two papers (see Schedule). For each paper, please send me one question that you want to be answered or discussed in class (on the day preceding the class, before midnight).

Presentation: An oral presentation of 30-45 minutes, typically based on a core paper and maybe some complementary reading. Please contact me (1) when you have been assigned a topic/paper and want to start working on it; (2) when you have a pre-final draft version of the presentation. After your presentation I will provide feedback to you. The final version of your slides will be posted on the course homepage.

Term Paper: MSc students opting for the 7 CP version have to write a term paper (approx. 15 pages, deadlines see below). The topic of the paper need not be identical or overlap with the topic of your oral presentation.

Specific instructions for term papers and the use of LMM-based generative AI tools (e.g., ChatGPT or similar): It is your responsibility to verify any information that you include in the term paper with respect to correctness and reliability of the source. LLM tools generate text based on probabilities without guaranteeing the veracity of information. This also pertains to bibliographic sources, which need to be verified. If you use such tools in the process of writing your term paper, you must indicate this in the declaration that the paper is your own academic work. You must also provide the prompts you used. See UdS guidelines (page 7).
