National Early Intervention Longitudinal Study (NEILS): Program Director Survey
Directors of programs serving the children and families during their first six months in service complete a mail survey on the characteristics of their programs such as the number and…

National Early Intervention Longitudinal Study (NEILS): Service Record A
For the study, every six months an early intervention professional completed a questionnaire on received services, including information regarding the transition out of early intervention.

The Modified Group Delay Function and Its Application to Phoneme Recognition
Exploring a new spectral representation of speech signals through group delay functions.

National Early Intervention Longitudinal Study (NEILS): Service Record B
An early intervention professional completed a questionnaire on the services provided to each NEILS family, including information regarding the transition out of early intervention. Version A of the service record…

Prosodic Knowledge Sources for Automatic Speech Recognition
We investigate three models, each exploiting a different level of prosodic information, in rescoring N-best hypotheses according to how well recognized words correspond to prosodic features of the utterance.

The Robustness of an Almost-Parsing Language Model Given Errorful Training Data
An almost-parsing language model has been developed that provides a framework for tightly integrating multiple knowledge sources. Lexical features and syntactic constraints are integrated into a uniform linguistic structure (called…

Training a Prosody-Based Dialog Act Tagger from Unlabeled Data
Here we investigate the use of unlabeled data for training HMM-based dialog act taggers. Three techniques are shown to be effective for bootstrapping a tagger from very small amounts of…

A Prosody-based Approach to End-of-Utterance Detection That Does Not Require Speech Recognition
In this paper we demonstrate that the improvements due to the prosodic knowledge can be realized largely without alignment information, i.e., without requiring a speech recognizer. A prosodic end-of-utterance detector…

National Early Intervention Longitudinal Study (NEILS): Early Intervention Service Provider Survey
Survey of early intervention service providers used in the SRI-led National Early Intervention Longitudinal Study (NEILS).

Fast Symbolic Evaluation of C/C++ Preprocessing Using Conditional Values
We present a new approach for symbolic evaluation that can efficiently compute these conditions by binding variables to conditional values and avoiding the path feasibility analysis of traditional symbolic evaluation.
