Early Effects

ABSTRACTThe possibility that early linguistic experience affects infant speech perception was investigated in a cross-linguistic study with naturally produced speech stimuli. Using the Visually Reinforced Infant Speech Discrimination paradigm, three contrasts were presented to Spanish-and English-learning infants 6–8 months of age. Both groups of infants showed statistically significant discrimination of two contrasts, English and Czech. Only the Spanish-learning infants provided evidence of discrimination of the Spanish contrast. The groups discriminated the English contrast at similarly high levels, but the Spanish-learning infants showed significantly higher performance than the English on both the Spanish and the Czech contrast. The results indicate that early experience does affect early discrimination, and further (since the stimuli were natural) that the effect may be of practical consequence in language learning.

Presentation Level

Several investigations were performed with normal hearing subjects to determine the effects of presentation level and signal-to-babble ratio on the speech perception in noise (SPIN) test. The SPIN test contains sentences that simulate a range of contextual situations encountered in everyday speech communication. Findings from several representative patients with sensorineural hearing loss demonstrate the possible clinical utility of the test to measure the effects of context on speech discrimination.

The Impact

Background: Speech perception measures have long been considered an integral piece of the audiological assessment battery. Currently, a prelinguistic, standardized measure of speech perception is missing in the clinical assessment battery for infants and young toddlers. Such a measure would allow systematic assessment of speech perception abilities of infants as well as the potential to investigate the impact early identification of hearing loss and early fitting of amplification have on the auditory pathways. Purpose: To investigate the impact of sensation level (SL) on the ability of infants with normal hearing (NH) to discriminate /a-i/ and /ba-da/ and to determine if performance on the two contrasts are significantly different in predicting the discrimination criterion. Research Design: The design was based on a survival analysis model for event occurrence and a repeated measures logistic model for binary outcomes. The outcome for survival analysis was the minimum SL for criterion and the outcome for the logistic regression model was the presence/absence of achieving the criterion. Criterion achievement was designated when an infant’s proportion correct score was >0.75 on the discrimination performance task. Study Sample: Twenty-two infants with NH sensitivity participated in this study. There were 9 males and 13 females, aged 6–14 mo. Data Collection and Analysis: Testing took place over two to three sessions. The first session consisted of a hearing test, threshold assessment of the two speech sounds (/a/ and /i/), and if time and attention allowed, visual reinforcement infant speech discrimination (VRISD). The second session consisted of VRISD assessment for the two test contrasts (/a-i/ and /ba-da/). The presentation level started at 50 dBA. If the infant was unable to successfully achieve criterion (>0.75) at 50 dBA, the presentation level was increased to 70 dBA followed by 60 dBA. Data examination included an event analysis, which provided the probability of criterion distribution across SL. The second stage of the analysis was a repeated measures logistic regression where SL and contrast were used to predict the likelihood of speech discrimination criterion. Results: Infants were able to reach criterion for the /a-i/ contrast at statistically lower SLs when compared to /ba-da/. There were six infants who never reached criterion for /ba-da/ and one never reached criterion for /a-i/. The conditional probability of not reaching criterion by 70 dB SL was 0% for /a-i/ and 21% for /ba-da/. The predictive logistic regression model showed that children were more likely to discriminate the /a-i/ even when controlling for SL. Conclusions: Nearly all normal-hearing infants can demonstrate discrimination criterion of a vowel contrast at 60 dB SL, while a level of ≥70 dB SL may be needed to allow all infants to demonstrate discrimination criterion of a difficult consonant contrast.

(1) Background: Research has demonstrated that early intervention for children who are hard-of-hearing (CHH) facilitates improved language development. Early speech perception abilities may impact CHH outcomes and guide future intervention. The objective of this study was to examine the use of a conditioned head turn (CHT) task as a measure of speech discrimination in CHH using a clinically feasible protocol. (2) Methods: Speech perception was assessed for a consonant and vowel contrast among 57 CHH and 70 children with normal hearing (CNH) aged 5–17 months using a CHT paradigm. (3) Results: Regardless of hearing status, 74% of CHH and 77% of CNH could discriminate /a-i/, and 55% of CHH and 56% of CNH could discriminate /ba-da/. Regression models revealed that both CHH and CNH performed better on /ba-da/ at 70 dBA compared to 50 dBA. Performance by hearing age showed no speech perception differences for CNH and children with mild hearing loss for either contrast. However, children with hearing losses ≥ 41 dB HL performed significantly poorer than CNH for /a-i/. (4) Conclusions: This study demonstrates the clinical feasibility of assessing early speech perception in infants with hearing loss and replicates previous findings of speech perception abilities among CHH and CNH.

Evaluation of babies with hearing aids using visual reinforced ınfant speech discrimination method: A case series Speech perception measurements are an important part of the audiology test battery. It is important to investigate hearing loss in the early period and to evaluate the auditory pathway in terms of speech perception for appropriate amplification. Due to the level of language development in infants, it is not possible to objectively evaluate speech perception skills with the speech test battery used in adults. It is necessary to use a test battery that gives objective results for the measurement of speech perception in infants. Visual Reinforcement Infant Speech Discrimination (VRISD) method is the most commonly used test technique to evaluate speech discrimination skills in infants. The aim of this study is to evaluate the speech discrimination skills of 3 babies aged 6-18 months, who are hearing aid users, with the VRISD test method. In the VRISD test protocol used in this study, test stimuli were created by matching /a/ with /i/ and /ba/ with /da/ speech stimuli. These stimulus pairs are arranged as one target sound and the other background sound, and they are presented at 70 dB via loudspeaker by creating a repeating sound sequence. Animated video that attracts the attention of the baby was used as visual reinforcement. Speech discrimination skills of 3 babies with bilateral hearing aids were evaluated with the VRISD test, and the results of the cases are presented. As a result of the study, speech discrimination skills of babies with hearing aids will be evaluated with the VRISD test method. These results contribute to habilitation and amplification programming. Keywords: Hearing aid, speech perception, pediatric audiology
