Analyzing Icelandic conversation using State-of-the-Art ASR models
… and fine-tuning of transformer-based Automatic Speech Recognition (ASR) systems applied to Icelandic conversational speech, with a primary focus on OpenAI’s Whisper model and a secondary fo- cus on Meta’s Wav2Vec 2.0. The study uses the Spjallrómur dataset, a 21-hour unscripted dialogue dataset …

Feature-based pronunciation modeling for automatic speech recognition
Spoken language, especially conversational speech, is characterized by great variability in word pronunciation, including many variants that differ grossly from dictionary prototypes. This is one factor in the poor performance of automatic speech recognizers on conversational speech. One approach …

Modeling spontaneous speech variability for large vocabulary continuous speech recognition
… techniques for improved treatment of spontaneous speech variabilities in large vocabulary automatic speech recognition are developed and evaluated on US English conversational speech and spontaneous medical dictations. Two main aspects of spontaneous speech modeling are addressed: The general …

Children's Perception of Conversational and Clear American-English Vowels in Noise
… have examined children's perception of clear speech in the presence of background noise. Although accurate vowel perception is important for listeners' comprehension, no study has focused on whether vowels uttered in clear speech aid intelligibility for children listeners. In the present …

Pronunciation modeling for large vocabulary speech recognition
The large pronunciation variability of words in conversational speech is one of the major causes of low accuracy in automatic speech recognition (ASR). Many pronunciation modeling approaches have been developed to address this problem. Some explicitly manipulate the pronunciation dictionary as well …

Relationships between cognitive status, speech impairment and communicative participation in Parkinson’s disease
… the relationships between cognitive status, speech impairment and communicative participation in Parkinson’s disease. Introduction: Speech and communication difficulties, as well as cognitive impairment, are prevalent in Parkinson’s. The contributions of cognitive impairment and acoustic …

Factors Affecting Pretonic Deletion in English Syllables: A Corpus Study
… that is associated with fast and/or conversational speech is <em>massive reduction</em>, in which entire syllables are deleted. We focus on a subtype of massive reduction, pretonic vowel deletion, where the vowel in an unstressed syllable is deleted and the flanking consonants form an …

An acoustic analysis of labialization of coronal nasal consonants in American English
A challenge for speech recognition models is to account for the variation between natural connected speech forms and the canonical forms of the lexicon. This study focuses on one particular sound change common in conversational speech, in which word-final coronal nasal consonants undergo place …

Normalization in the acoustic feature space for improved speech recognition
… which improve the robustness of automatic speech recognition systems. It is shown that there is a fundamental mismatch between training and test data which causes degraded recognition performance. Adaptation and normalization, basic strategies to reduce the mismatch, are introduced and …

Accuracy of Automated Developmental Sentence Scoring Software
… expressive syntax within the context of a conversational speech sample. Automated DSS programs may increase efficiency of DSS analysis; however the program must be accurate in order to yield valid and reliable results. A recent study by Sagae, Lavie, and MacWhinney (2005) proposed a new …

A Digital System for Multiplex Speech Transmission
… to remove redundant samples from the digitized speech signal. A computer aided study of conversational speech revealed that such a strategy would eliminate e substantial fraction of samples. The transmitted digit-rate is reduced, compared with PCM, by having fewer timeslots in the frame of …

Disfluencies and Rate of Speech of Young Adult Normal Talkers in an Interview Situation
… little research has been conducted concerning speech disfluency in normal talkers. Virtually no data are available to document percentage of disfluency and rate of speech of nonstutterers in a speech pathology clinical interview situation. Consequently, it is difficult to compare progress made …

Properties of naturally produced clear speech at normal rates and implications for intelligibility enhancement
… clearly[45, 55, 42]. While producing clear speech, however, talkers often reduce their speaking rate significantly[46, 55]. A recent study[28] showed that speaking slowly is not responsible for the high intelligibility of clear speech, since talkers can produce clear speech at normal rates …

The Identification of Spanish-Speaking Children with Speech and Language Handicaps: An Analysis of Current Assessment Practices in Speech and Language Therapy Programs with Proposed Assessment Guidelines
… study were (1) to examine the procedures used by speech-language pathologists in identifying Spanish-speaking students with speech and language handicaps, (2) to determine the extent to which practicing speech-language pathologists are qualified to conduct these evaluations, and (3) to develop a …

A continuous silent speech recognition system for AlterEgo, a silent speech interface
… thesis, I present my work on a continuous silent speech recognition system for AlterEgo, a silent speech interface. By transcribing residual neurological signals sent from the brain to speech articulators during internal articulation, the system allows one to communicate without the need to speak …

Laryngeal function associated with changes in lung volume during voice and speech production in normal speaking women
… the patterns of change were similar for both speech tasks. Individual subject data reflected alternative patterns of laryngeal behavior for achieving the speech tasks. The results were interpreted as evidence that laryngeal function during voice production is clearly influenced by the lung …

Voice Call Capacity Over Wireless Mesh Networks
… ad hoc network. We begin with the modelling of conversational speech and define a six state semi-Markov voice model based on ITU-T P59 recommendation. We perform a theoretical analysis of the voice model and compare it with results obtained via simulations. Using a Java based IEEE 802.11 medium …

Exploring Perceptions of Second Language Speech Fluency Through Developing and Piloting a Rating Scale for a Paired Conversational Task
Much research has explored how perceptions of speech fluency are influenced by a variety of temporal speech features (e.g. speech rate). However, less is known about the influence of non-temporal and conversational speech characteristics, as well as listener characteristics such as accent …
