Different Error Patterns Of /L/ In Children And Speech-Language Pathologists' Perception And Treatment, Grace E. Lemoine

LSU Master's Theses

Children often simplify target speech sounds using phonological processes, or common developmental error patterns. However, some children produce less common error patterns that differ from common errors. In the current study, less common errors involving /l/ sounds were studied as the phoneme /l/ is a sound that is subject to frequent misarticulations in young children and perceptual confusion among listeners. The current study focused on less common errors because studies have suggested that atypical errors can indicate weak phonological representations and poor phonological awareness skills, which can have long-term effects on children’s literacy skills. Therefore, the aim of the current …

Remote-Frequency Masking And Speech Perception In Adults, Taylor L. Arbogast

Dissertations, 2020-current

The primary purpose of this study is threefold: to use SRT measurements to examine the effect of various remote-frequency, narrowband maskers on adult’s perception of narrowband speech, to compare the performance between low and high band speech stimuli, and to evaluate the combination of these approaches by examining the correlation between the masking effect observed with speech and pure tone stimuli. Twelve subjects aged 22-34, with hearing thresholds no worse than 15 dB HL for frequencies 500-8000 Hz, participated in two listening tasks. In the speech perception task, coordinate response measure (CRM) sentences and their maskers were separately filtered into …

Lexical Properties Of Perceptual Errors Made By Younger And Older Adults Listening To Speech In Multitalker Babble, Hannah Blythe Vickery

Theses and Dissertations

Purpose: The purpose of this error analysis was to analyze the lexical properties of misperceptions made when listening to speech in multitalker babble.

Methods: Twenty young adults with normal hearing (YNH), 20 older adults with normal hearing (ONH), and 22 older adults with hearing impairment (OHI) completed a speech-in-babble task. Participants were asked to repeat the final word in 25 high and 25 low context sentences. On each trial, participants either responded with the correct target word, a misperception error, or skipped the trial response. Misperceptions were compiled and analyzed according to their lexical properties.

Results: Results of this study …

Encoding And Perception Of Voicing And Aspiration In Native And Non-Native Listeners In Quiet And In Background Noise, Reethee Antony

Dissertations, Theses, and Capstone Projects

The perception and encoding of voice cues in consonants have been well studied, whereas there has been relatively little research on aspiration. The current study examined the encoding and perception of aspiration and voicing in Hindi, American English, and Tamil listeners when relevant cues were and were not degraded by noise. This study is novel because of the inclusion of aspiration, the language groups, inclusion of noise masking, and inclusion of auditory evoked potentials (in addition to behavioral testing).

The first aim was to determine whether language groups for whom aspiration and/or voicing is phonemically contrastive show better perception and …

The Impact Of Childhood Music Experience On Speech Perception And Processing: A Systematic Review, Erika Lanham

Dissertations, Theses, and Capstone Projects

Objective: The purpose of this investigation was to conduct a systematic review of the literature that addresses the impact of childhood musical experience on speech perception and processing abilities. Specifically, this review assessed how musical training impacted scores on both objective and behavioral tests of speech perception/processing in children. This analysis contributes to a better understanding of the effects of individual musical experience in childhood on our ability to perceive and process speech in a variety of listening conditions. This analysis also determined the clinical implications of such findings.

Methods: A comprehensive search utilizing the Web of Science database accessible …

Perception And Production Of /V/ And /W/ In Hindi Speakers, Vikas Grover

Dissertations, Theses, and Capstone Projects

This dissertation examines the ability of Hindi speakers to identify, discriminate and produce two English phonemes /v/ and /w/ which are difficult for Hindi speakers to distinguish. In Hindi, /v/ and /w/ are used interchangeably. This pattern of use has transferred to Indian English, resulting in English /v/ and /w/ words showing variable pronunciations (e.g., “whale” or “vale” for the word “whale”). Hindi speakers were asked to identify, discriminate and produce tokens of /v/ and /w/. This study also examined whether experience with American English, related to the length of residence (LOR) in the US affects Hindi listeners’ perception and …

List Equivalency Of The Azbio Sentence Test, Lauren C. Bush

Honors Theses

The AzBio Sentence Test was developed as a measure of speech perception abilities and intended to be more reliable and closer to real life conditions than the previous speech perception measures commonly used. The purpose of speech perception measures is to partially determine cochlear implant candidacy as well as pre- and post-outcomes of cochlear implantation. The AzBio Sentence test is composed of 15 lists of 20 sentences each. There is limited research conducted on the equivalency of each of these lists. Of the previous limited reasearch conducted, one study found that only 10 of the 15 lists were equivalent. The …

The Influence Of Situational Cues On A Standardized Speechreading Test, Maria Navarro Montserrat

Dissertations and Theses

The purpose of the present study was to determine the influence of situational cues on a standardized speechreading test in order to assess an individual's natural speechreading ability. The widely used, standardized Utley Lipreading Test was selected to which photoslides of message-related situational cues were added. The Utley Lipreading Test consists of two relatively equivalent test lists, containing series of unrelated sentences.

A Comparison Of The Articulatory Proficiency Between Stutterers And Nonstutterers While In A State Of Oral Sensory Deprivation, Clifford Saul Goldman

Dissertations and Theses

The purpose of this thesis was to determine if stutterers monitor speech production differently than nonstutterers while in a state of oral sensory deprivation. The specific questions asked were:

1. Does an imposed oral somesthetic feedback deficit hinder articulation proficiency more in a nonstuttering sample than in a stuttering sample?
2. If the articulation proficiency is deficient in both samples, does the nature of the errors differ between the two samples?

A Comparative Study Of Perceptual Ratings And Fundamental Frequency In Female And Male Esophageal Voices, Anne Terese Heinrich

Dissertations and Theses

This study proposed to determine if male and female esophageal voices were rated in the same manner by naïve listeners. Answers to the following questions were sought:

1. Is there a difference in the social acceptability ratings given to female esophageal voices compared to male esophageal voices, when the speakers are matched for speaking ability?
2. Does a relationship exist between the fundamental frequencies of female esophageal voices and ratings of social acceptability given by naïve listeners?
3. Does a relationship exist between the fundamental frequencies of male esophageal voices and ratings of social acceptability given by naïve listeners?
4. Do male and female …

A Study Of The Perceptual Parameters Of Voice In Aging Females, Barbara Ann Mathers

Dissertations and Theses

An interest in understanding the aging processes, as they relate to voice, has prompted research investigating physiological, acoustical, and perceptual attributes of the aging vocal mechanism. Recently, it has been demonstrated that perceptual parameters, in older male voices, differentiate speakers according to age estimations, as determined by a group of listeners.

The purpose of this study was to determine the perceptual characteristics of the female voice which are associated with perceived age, as contrasted to chronological age.

An Investigation Of The Consistency Of Judgments Regarding Successive Approximations Of /R/, Scott Robert Lane

Dissertations and Theses

This investigation sought to determine the accuracy and consistency of judgements made by three groups of judges, relative to successive approximations of /r/. The three groups were made up of speech pathologists, student trainees, and untrained individuals, respectively. It was the task of these judges to rank order three /r/ productions into the following categories: correct; partially correct; and incorrect. This task is basically the same as reinforcing approximations of /r/ within the therapy situation, and appears not to require extensive training. Many authors (Curry et al., 1943; Perrin, 1954; Oyer, 1959; Siegel, 1962; Irwin, 1965; and Elbert et al., …
