Description

This course introduces students to the computational linguistic approach to intonation.

Requirements

The major requirements of the course are a midterm, a final, and a 3-part class project.  Class participation will also contribute to your final grade.  The project involves building a spoken dialogue system in a domain of your choice.  You will build a text-to-speech (TTS) system and an automatic speech recognition (ASR) system from components we will provide; the dialogue component will involve building a simple system to put inputs and outputs together to accomplish some interesting and useful or fun task.  You are encouraged to do these projects in teams of 2-3.  There will be several project deadlines during the term where we evaluate your project description, your TTS system, your ASR system, and the overall project.  Project deadlines  will be allowed total of 5 late days with no questions asked; after that, 10% per late day will be deducted from the grade for that component, unless you have a note from your doctor.  Do not use these up early!  Save them for real emergencies. 

All students are required to have a Computer Science Account for this class. To sign up for one, go to the CRF website and then click on "Apply for an Account".  The Speech Lab is available for use in homeworks as needed on a signup basis.  Some parts of the project must be done in the Lab.

 

Academic Integrity

Copying or paraphrasing someone's work (code included), or permitting your own work to be copied or paraphrased, even if only in part, is not allowed, and will result in an automatic grade of 0 for the entire assignment or exam in which the copying or paraphrasing was done. Your grade should reflect your own work. If you believe you are going to have trouble completing an assignment, please talk to Prof. Hirschberg or to Robert Coyne in advance of the due date.  Please see the university policy.

Required texts:

    Daniel Jurafsky and  James H. Martin Speech and Language Processing (second edition). Pearson: Prentice Hall. 2009.  See errata before you do each reading assignment.  There are some typos in algorithms.

    Keith Johnson. Acoustic & Auditory Phonetics (second edition). Blackwell.  2003.

    Other required readings are available online via links from this syllabus.

Grading:

  • 40% Exams

  • 60% Course Project

  •           Class participation will be taken into account in calculating the final grade.

Homework submission procedure is described HERE.
