Description

This course introduces students to research in spoken language in computational linguistics, aka natural language processing (NLP). We will study the different `meanings' that can be conveyed by the way that speakers produce sentences, techniques for analyzing spoken language, methods of developing speech technologies such as text-to-speech systems and speech recognition systems, and applications of speech technologies in the real world, such as spoken dialogue systems (SDS).  Students will build an SDS in a domain of their choice, working in small teams.   NB: This course can be counted as a PhD elective in Advanced AI.  It is a requirement for the MS NLP Track.  There are no official prerequisites for this course except Data Structures or equivalent, and no prior knowledge of NLP will be assumed.

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:
