Speech intelligibility can be defined as how clearly a person speaks so that his or her speech is comprehensible to a listener . Reduced speech intelligibility leads to misunderstanding, frustration, and loss of interest by communication partners. As a result, communication decreases or remains at a low level.
Intelligible speech is critical for successful spoken communication. Intelligibility has been defined as the extent to which an acoustic signal, generated by a speaker, can be correctly recovered by a listener (Kent, Weismer, Kent, & Rosenbek, 1989).Central to this definition is the dyadic nature of intelligibility, requiring at a minimum a speaker who produces a speech signal and a listener ...
Additionally, children with speech and language delays, hearing loss, genetic syndromes, or other disorders are likely to have lower speech intelligibility than their peers. Speech Intelligibility by Age. In a 2021 study on speech intelligibility in children, Hustad et al. sampled the speech of 538 typically developing children, had a group of ...
The age of steepest growth for the 50th percentile was 30-31 months for both single-word and multiword intelligibility and was later for children in lower percentiles. The maximum growth rate was 1.7 intelligibility percentage points per month for single words and 2.5 intelligibility percentage points per month for multiword intelligibility.
The study of speech intelligibility has received increasing large-scale attention from a developmental perspective. In developing the Test of Children's Speech (TOCS+; Hodge & Daniels, 2007) and establishing its validity, Hodge and Gotzke (2014) examined intelligibility and speaking rate in typically developing English-speaking children (n = 48, ages 3–6 years).

(e.g., speech language pathologists or phoneticians), and the nature of speech material (elicited vs. spontaneous; sin-gle words vs. sentences vs. discourse or conversation). In a recent study examining relationships among different mea-sures of intelligibility obtained from the same children, Natzke et al. (2020) found weak associations ...
Speech samples were collected using the materials of the Bogenhausen Dysarthria Scales for Childhood Dysarthria, a German assessment tool for childhood dysarthria, and analyzed following established auditory-perceptual criteria on relevant speech functions. To assess intelligibility, naïve listeners transcribed sentences repeated by the children.
Artificially synthesized speech was generated by three commercial TTS platforms: Amazon Polly, Microsoft Azure Text-To-Speech and Google Text-To-Speech. The researchers further transcribed those speech recordings in noisy environments using five ASR platforms and found that two of the systems tested recognized 10% more words than did their ...
Keywords: speech intelligibility, hearing aid benefit, realistic speech, clinical assessment development, speech in noise, ECO-SiN. Introduction. Among the primary functions of speech-in-noise testing are the prediction of speech intelligibility and device benefit outside the clinic or laboratory conditions in which testing is conducted.
Conversational speech is the most socially-valid context for evaluating speech intelligibility, but it is not routinely examined. This may be because it is difficult to reliably count the number of words in ... review of published data and examined structural statistics from a large number of child
Intelligibility measures, which assess the number of words or phonemes a listener correctly transcribes or repeats, are commonly used metrics for speech perception research. While these measures have many benefits for researchers, they also come with a number of limitations. By pointing out the stre …
Parents, teachers and even SLPs can become laser focused on accuracy and percentages as students settle into their speech therapy routines. Intelligibility—how effectively a person can be understood by others—offers a fuller picture of a student’s progress and may be easier to measure than you think!

Speech intelligibility, loneliness, and sense of coherence among deaf and hard-of-hearing children in individual inclusion and group inclusion.
Intelligibility becomes particularly difficult in ataxia with longer words, such as statistics or Mississippi. However, in a recent research study, people with ataxia generally had relatively high intelligibility at 70% or higher (Hilger, Cloud, & Fahey, 2022). This intelligibility is particularly high when compared with other neurological ...
Keywords: dysarthria, speech intelligibility, speech-language pathologists. 1. Introduction. Broadly, speech intelligibility refers to how well a listener can understand a speaker’s message [1,2]. In clinical settings, intelligibility is often used as an index of communication outcomes for those with speech disorders .
