Vocabulary development and intervention for English learners in the early grades.

The purpose of this chapter is to describe the vocabulary development and promising, evidence-based vocabulary interventions for English learners (ELs) from preschool through second grade. To achieve this purpose, we have taken six steps. First, we describe the elements of language development in the native language (L1) and a second language (L2) and how these elements relate to three phases of reading development (i.

Computerized script training for aphasia: preliminary results.

Purpose: This article describes computer software that was developed specifically for training conversational scripts and illustrates its use with 3 individuals with aphasia.

Method: Three participants with chronic aphasia (Broca's, Wernicke's, and anomic) were assessed before and after 9 weeks of a computer script training program. For each participant, 3 individualized scripts were developed, recorded on the software, and practiced sequentially at home.

Accurate visible speech synthesis based on concatenating variable length motion capture data.

We present a novel approach to synthesizing accurate visible speech based on searching and concatenating optimal variable-length units in a large corpus of motion capture data. Based on a set of visual prototypes selected on a source face and a corresponding set designated for a target face, we propose a machine learning technique to automatically map the facial motions observed on the source face to the target face. In order to model the long distance coarticulation effects in visible speech, a large-scale corpus that covers the most common syllables in English was collected, annotated and analyzed.
