Learning objectives:
  To provide students with the knowledge of basic characteristics of speech signal in relation to production and hearing of speech by humans. To describe basic algorithms of speech analysis common to many applications. To give an overview of applications (recognition, synthesis, coding) and to inform about practical aspects of speech algorithms implementation.
Description:
  Applications of speech processing, digital processing of speech signals, production and perception of speech, introduction to phonetics, pre-processing and basic parameters of speech, linear-predictive model, cepstrum, fundamental frequency estimation, coding - time domain and vocoders, recognition - DTW and HMM, synthesis. Software and libraries for speech processing.
Learning outcomes and competencies:
  The students will get familiar with basic characteristics of speech signal in relation to production and hearing of speech by humans. They will understand basic algorithms of speech analysis common to many applications. They will be given an overview of applications (recognition, synthesis, coding) and be informed about practical aspects of speech algorithms implementation. The students will be able to design a simple system for speech processing (speech activity detector, recognizer of limited number of isolated words), including its implementation into application programs.
Syllabus of lectures:
 
  • Introduction, applications of speech processing, sciences relevant for SP, informational content of speech.
  • Digital processing of speech signals.
  • Speech production and perception, basic notions from psycho-acoustics, applications in speech processing. 
  • Introduction to phonetics, international norms for phoneme mark-up.
  • Pre-processing and basic parameters of speech.
  • Linear-predictive model, spectrum using LP, applications of LP. 
  • Cepstral analysis, Mel-frequency cepstrum.
  • Determination of fundamental frequency.
  • Speech coding
  • Speech recognition - dynamic programming DTW, hidden Markov models HMM
  • Speech synthesis
  • Software and libraries for speech processing.
Syllabus of numerical exercises:
 
  • Parameterization, DTW, HMM.
  • Presentation of projects.
Syllabus of computer exercises:
 
    Except the last one, Matlab is used in labs.
  • Frames, windows, spectrum, pre-processing.
  • Linear prediction (LPC).
  • Fundamental frequency estimation.
  • Coding.
  • Recognition - Dynamic time Warping (DTW).
  • Recognition - hidden Markov models (Hidden Markov Model Toolkit - HTK).

Controlled instruction:
  Presence in any form of instruction is not compulsory. An absence (and hence loss of points) can be compensated in the following ways: 
  1. presence in another laboratory group dealing with the same task. 
  2. showing a summary of results to the tutor at the next lab. 
  3. sending a short report (summarizing the results of the missed lab and answering the questions from the assignment) to the tutor, in 14 days after the missed lab. 
Progress assessment:
  
  • mid-term test 14 pts
  • projects 29 pts
  • presentation of results in computer labs 6 pts
