based on the controversial beliefs among l2 teachers about effective corrective feedback (cf) strategies, recast and prompts as 2 kinds of cf have drawn the attention of l2 researchers(e.g., braidi, 2002; iwashita, 2003; loewen & philp, 2006; panova & lyster, 2002; sheen, 2004). despite these numbers of studies, debate continues to exist about their usefulness as a cf technique. whereas...

A significant amount of speech is typically required for speaker verification system development and evaluation, especially in the presence of large intersession variability. This paper introduces a source and utterance-duration normalized linear discriminant analysis (SUN-LDA) approaches to compensate session variability in short-utterance i-vector speaker verification systems. Two variations ...

OBJECTIVE To determine whether communication at 2 years predicted communication at 4 years in children with cerebral palsy (CP); and whether the age a child first produces words imitatively predicts change in speech production. METHOD 30 children (15 males) with CP participated and were seen 5 times at 6-month intervals between 24 and 53 months (mean age at time 1 = 26.9 months (SD 1.9)). Var...

In a conversational context, user converses with system through sequence of natural-language questions, i.e., utterances. Starting from given subject, the conversation evolves sequences utterances and replies. The retrieval documents relevant to an utterance is difficult due informal use natural language in speech complexity understanding semantic context coming previous We adopt 2019 TREC Conv...

Utterance clustering is one of the actively researched topics in audio signal processing and machine learning. This study aims to improve performance utterance by multichannel (stereo) signals. Processed signals were generated combining left- right-channel a few different ways then extracting embedded features (also called d-vectors) from those processed applied Gaussian mixture model for super...

Text condensation aims at shortening the length of an utterance without losing essential textual information. In this paper, we report on the implementation and preliminary evaluation of a sentence condensation tool for Greek using a manually constructed table of 450 lexical paraphrases, and a set of rules that delete syntactic subtrees that carry minor semantic information. Evaluation on two s...
