“…In the deaf and hard of hearing population, researchers are concerned with the question of productive development in an imperfect auditory environment. Many investigators have run correlations between the amount of hearing loss and the intelligibility of speech, and also perception and production development after children receive a cochlear implant (e.g., Golfeto & de Souza, 2015; Song et al, 2015; Tseng, Kuei, & Tsou, 2011).…”

Cognitive scientists across disciplines have shown a vested interest in examining if and how the speech perception and production modalities are connected. The field of second language (L2) acquisition contributes to this discussion by investigating the effects of auditory training of L2 sounds on pronunciation. This meta-analysis offers a comprehensive view of the last 25 years of L2 perception training studies that test for effects in production. The results indicate that the two modalities are connected, insomuch as training the perception of L2 sounds can induce positive change in the productive mode as well. The data indicate that strictly controlled perception training led to medium-sized improvements in perception (d= 0.92,SD= 0.96) and small improvements in production (d= 0.54,SD= 0.45). A correlation analysis suggests a small- to medium-sized relationship between perception and production gains, although this relationship was not significant. The production of obstruents improved to a larger degree than sonorants or vowels, and an additional six moderating variables influenced the magnitude of the production effect sizes. We caution researchers to not equate the connection of the two modalities in long-term linguistic development to real-time neurological processing, and we end with five recommendations for the domain of L2 phonetic training research.

“…A sophisticated assessment of oral language production is subject to multiple linguistic considerations, e.g., segment clarity, lexical use, sentence structure and socio-pragmatic, communicative skills. Among them, speech intelligibility is often evaluated for clarity and fluency of vowels, consonants, tones, rhythm, and intonation [5][6][7]. Our study focuses on speech intelligibility that involves only segment clarity and lexical prosody.…”

Speech difficulties of children may result from pathological problems. Oral language is normally assessed by expertdirected impressionistic judgments on varying speech types. This paper attempts to construct automatic systems that help detect children with severe speech problems at an early stage. Two continuous speech types, repetitive and storytelling speech, produced by Chinese-speaking hearing and hearing-impaired children are applied to Long Short-Term Memory (LSTM) and Universal Transformer (UT) models. Three approaches to extracting acoustic features are adopted: MFCCs, Mel Spectrogram, and acoustic-phonetic features. Results of leave-one-out cross-validation and models trained by augmented data show that MFCCs are more useful than Mel Spectrogram and acoustic-phonetic features. Respective LSTM and UT models have their own advantages in different settings. Eventually, our model trained on repetitive speech is able to achieve an F1-score of 0.74 for testing on storytelling speech.

“…6. From the figure, we find out that the second consonant presents a higher average error rate than the first one [4]. In order to distinguish automatically whether vowel /e/ is pronounced correctly or not to use computer as a tool, we have investigated the difference between the pronunciation of native Chinese speakers and Japanese students.…”

“…Some katakana-English dictionaries are good example for Japanese. Hence, there are many researchers have directly investigated the characteristics of pronunciation of Chinese [2]- [4] and approved some information processing techniques [5], [6]. The single vowel analysis and Computer Assisted Language Learning (CALL) [7] have been actively researched.…”

In this paper, we investigate the features of the syllables including vowel /e/, /u/ and /ü/ which are pronounced by Chinese learners. How the pronunciation error of vowel /e/ being influenced by position of twosyllable word, tone as well as consonant is mainly discussed. As results, firstly it is understood that the position of twosyllable word does not affect the pronunciation of vowel /e/, and secondly, for tone, the pronunciation error rate is highest when the syllable is the third of tone. In order to objectively judge the pronunciation state, we used the value of the first formant frequency in the beginning, middle and ending part of vowel /e/. The proposed method is confirmed by obtaining 80.1% correct rate when comparing the pronunciations with perception result between native Chinese students and Chinese learners of Japanese students using 54 Chinese words. 
