Each module leads you through the material in a specific order: simply follow the tabs from left to right. But do also explore the entire course content on your own, look ahead to what is coming later, and browse the rest of this website including the forums.
This course operates a policy of continuous improvement. You will find some content is not yet ready. Don’t worry, it will be ready in time for you to study it This year, we are making the following improvements:
- New PHON videos.
- New SIGNALS videos.
- New TTS videos.
- (The ASR videos will remain the same as last year.)
- New Jupyter notebooks, focusing on PHON and SIGNALS.
- More quizzes.
We have also made the following changes in the way the course is delivered:
- Replace the weekly whole-class lecture and large-group computer lab with small-group tutorials.
- For each tutorial group: two 50 minute tutorials per week.
- A more focussed topic for each tutorial, with specific tasks for you to complete in advance (individual, pair or group work).
In response to mid-course feedback, we have additionally:
- Added overview video(s) for modules 6 to 9. You should watch these before the live class.
- Scheduled a live class every Tuesday 11.10 to 13.00 on Teams to go over that video in an interactive fashion.
The readings are specified in each module and are categorised as
- Essential (read all, aiming to complete within the same week as the module)
- Recommended (read as many as you can, catching up when you have spare time)
- Extra (only read if you’re interested; some readings may be challenging; most are beyond the scope of the course)
