Words are built from smaller meaning bearing parts, called morphemes. As one word can contain multiple morphemes, one morpheme can be present in different words. The number of distinct words a morpheme can be found in is its family size. Here we used Birth-Death-Innovation Models (BDIMs) to analyze the distribution of morpheme family sizes in English and German vocabulary over the last 200 year...

This paper describes an approach for predicting both the vocabulary size and the resulting out-of-vocabulary rate (OOV-rate) for a hypothetical extension of an existing text corpus. By splitting the original corpus into two different sub-corpora, vocabulary and OOV-rate can be determined for that special constellation. Average values are calculated for all combinations of sub-corpora and can be...

Vocabulary size has been suggested as a useful measure of "verbal abilities" that correlates with speech recognition scores. Knowing more words is linked to better speech recognition. How vocabulary knowledge translates to general speech recognition mechanisms, how these mechanisms relate to offline speech recognition scores, and how they may be modulated by acoustical distortion or age, is les...

Kinki University, Japan [email protected] Recent research has shown that pairedassociate learning is an effective way to acquire second language vocabulary. However, much research in the field has measured small-scale vocabulary learning. This is due to the methods which learners used to conduct paired-associate learning: paper flash cards. This project sought to measure vocabulary growth ov...

This paper reports a study which investigated if there was a match between students’ English vocabulary size and the vocabulary load of a locally produced textbook. The analysis of the passages of the pre-university English textbook currently in use in Iran’s education system using RANGE program indicated that in order to comprehend the texts, students need to know not only words from 2000 high...

PURPOSE The goals of this study were to evaluate the impact of short-term phonological awareness (PA) instruction presented in children's first language (L1; Spanish) on gains in their L1 and second language (L2; English) and to determine whether relationships exist between vocabulary size, verbal working memory, and PA in Spanish-speaking English language learners (ELLs). METHOD Participants...
