Vocabulary and syntactic complexity in speech understanding systems

The Relationship between Syntactic and Lexical Complexity in Speech Monologues of EFL Learners

: This study aims to explore the relationship between syntactic and lexical complexity and also the relationship between different aspects of lexical complexity. To this end, speech monologs of 35 Iranian high-intermediate learners of English on three different tasks (i.e. argumentation, description, and narration) were analyzed for correlations between one measure of sy...

TINA: A Probabilistic Syntactic Parser for Speech Understanding Systems

A new natural language system, TINA, has been developed for applications involving speech understanding tasks, which integrates key ideas from context free grammars, Augmented Transition Networks (ATN's) [1], and Lexical Functional Grammars (LFG's) [2]. The parser uses a best-first search strategy, with probability assignments on all arcs obtained automatically from a set of example sentences. ...

Speech Understanding Systems

A three-stage solution for flexible vocabulary speech understanding

This paper discusses our three-stage approach to a flexible vocabulary speech understanding system, which can detect out-ofvocabulary (OOV) words, and hypothesize their phonetic and orthographic transcriptions. In the first stage, we introduce the column-bigram finite-state transducer (FST) which, while embedding ANGIE sublexical models, also supports previously unseen data from unknown words. ...

Syntactic Complexity of Russian Unified State Exam Texts in English: A Study on Reliability and Validity

In this study we analyze texts used in Russian Unified State Exam on English language. Texts that formed small research corpora were retrieved from 2 resources: official USE database as a reference point, and popular website used by pupils for USE training “Neznaika” (https://neznaika.pro/). The size of two corpora is balanced: USE has 11934 tokens and “Neznaika” - 11918 tokens. We share Biber’...
