ASR: Labs

Compulsory weekly lab sessions run in weeks 3-7, in which you will use OpenFst and Python to build your own small-vocabulary speech recognition system from scratch. All labs will run in Appleton Tower in room 5.05. You need only attend one lab session per week – you should already have been allocated one of the sessions.

• Lab group 01: Tuesdays 14.10
• Lab group 02: Tuesdays 15.10
• Lab group 03: Wednesdays 10.00

An introduction to the labs will be presented in Lecture 5. Exercises are accessed via a GitHub repository. You will work in pairs, with each pair submitting one set of solutions per lab. The five labs together are worth 10% of the total mark for the course.

Lab topics

• Lab 1 (Week 3): Building HMMs with OpenFst
• Lab 2 (Week 4): Computing HMM probabilities
• Lab 3 (Week 5): Viterbi decoding (1)
