SummaryA foundation course in speech processing for students of linguistics, informatics, and related subjects.
Course description The course is delivered as a combination of lectures, flipped classrooms, an online forum, short videos, readings, and practical exercises in the lab. The first hour of each lecture is generally devoted to foundation material, making the course accessible to students from a wide variety of backgrounds, including Linguistics, Informatics, and Music Technology.

Students deciding whether to take this course should visit the lecturer┐s blog http://www.speech.zone where much of the course material can be found.

In the lab, students investigate speech signals, experiment with a text-to-speech system, and build their own simple automatic speech recognition system, using industry-standard tools.

Fundamentals of speech processing: familiarity with waveforms, spectra, spectrograms, resonance, formants, human speech production and perception., perceptually-motivated frequency scales, time vs. frequency representations; conversion between the two, the Fourier transform, source-filter model of speech, hands on experience.

Automatic Speech recognition: components of a typical recogniser, parameterisation of the speech signal, dynamic time warping, distance measures, the Hidden Markov Model, the generative model paradigm, simple probability theory, conditional and joint probabilities, Bayes theorem, Gaussian probability density function, continuous density HMMs, monophone models with Gaussian observation densities, Viterbi algorithm for recognition, training from fully labelled data, Viterbi training, bigram language models.

Text-to-speech synthesis: components of a typical text-to-speech synthesiser, text analysis, phonology, finite-state automata, POS tagging, lexicon, phrasing, accents, F0, learning from data, CART models, waveform generation, concatenative methods, TD-PSOLA and linear prediction, F0 and duration modification.

Learning Outcomes
On completion of this course, the student will be able to:
  1. give an overview of the components of state-of-the art speech recognition and speech synthesis systems
  2. understand the main concepts and what each component does and describe a simple version of each component
  3. see what the difficult problems are in recognition and synthesis. They will also: use tools for visualising and manipulating speech waveforms
  4. experiment with two state-of-the-art speech technology systems and put experimental methodology into practice
  5. see how knowledge and skills from different areas come together in an interdisciplinary field
