The Multimedia Challenge
The Belmont Then and Now project, completed in 2000 by three 3rd grade classes from Central Elementary, helps put Belmont's changes over the past 150 years in perspective.

Consonant Discrimination in Elicited and Spontaneous Speech: A Case for Signal-Adaptive Front Ends in ASR
This work investigates an approach to add back such transient information to a speech recognizer, without losing the robustness of the standard acoustic models. We demonstrate a set of phonetically-motivated…

An Efficient Repair Procedure For Quick Transcriptions
The procedure we propose in this paper aims to em cleanse/ such quick transcriptions so that they align better with the acoustic evidence and thus provide for better acoustic models…

Dialogue Act Modeling for Automatic Tagging and Recognition of Conversational Speech
We describe a statistical approach for modeling dialogue acts in conversational speech, i.e., speech-act-like units such as Statement, Question, Backchannel, Agreement, Disagreement, and Apology. Our model detects and predicts dialogue…

Automatic Generation of Compact Programs and Virtual Machines for Scheme
We use a combination of techniques to automatically generate new instructions and new compact encodings for virtual instructions.

Do Technology Investments Pay Off? The Evidence Is In!
In a 5-year evaluation of the $6.6 million Challenge 2000 Multimedia Project, technology-using students surpassed nonparticipating peers in developing critical 21st-century job skills.

The SRI EduSpeak(TM) System: Recognition and Pronunciation Scoring for Language Learning
The EduSpeak(TM) system is a software development toolkit that enables developers of interactive language education software to use state-of-the-art speech recognition and pronunciation scoring technology.

Structured Argumentation for Analysis
We are developing a new methodology that retains the ease-of-use, familiarity, and (some of) the free-form nature of informal methods, while benefiting from the rigor, structure, and potential for automation…

Effects of Speech Recognition-based Pronunciation Feedback on Second-Language Pronunciation Ability
This study's goal was to determine whether receiving a particular type of feedback on nativeness of second-language accent positively influenced pronunciation over time.

Reusing Prior Knowledge: Problems and Solutions
In this paper, we focus on the process of reuse and report a case study on constructing a KB by reusing existing knowledge. The reuse process involved the following steps:…

Multiple-Target Tracking and Data Fusion via Probabilistic Mapping
A new approach is taken to address the various aspects of the multi-sensor, multi-target tracking (MTT) problem in dense and noisy environments. Instead of fixing the trackers on the potential…
