background and aim: speech understanding almost never occurs in silence. verbal communication often occurs in environments where multiple speakers are talking. in such environments, babbling noise masks speech comprehension. consonants, in comparison to vowels, are more sensitive to noise masking. consonants provide most acoustic information needed for comprehending the meaning of the word. sin...

background: according to previous studies, most of the speech recognition disorders in older adults are the results of deficits in audibility and auditory temporal resolution. in this paper, the effect of ageing on timecompressed speech and auditory temporal resolution by word recognition in continuous and interrupted noise was studied. methods: a time-compressed speech test (tcst) was conducte...

Reaction time of lexical decision and word recognition score were measured to investigate whether the neighborhood, a word candidate set with single mora substitution with a target word, has inhibitory effects on spoken word recognition in Japanese. Partial correlation analyses were conducted between subjects’ performance of spoken word recognition (reaction time and recognition score) and neig...

Accounts of bilingual cognitive advantages suggest an associative link between cross-linguistic competition and inhibitory control. We investigate this link by examining English-Spanish bilinguals' parallel language activation during auditory word recognition and nonlinguistic Stroop performance. Thirty-one English-Spanish bilinguals and 30 English monolinguals participated in an eye-tracking s...

Background: Many elderly individuals complain of difficulty in understanding speech in noise despite having normal hearing thresholds. According to previous studies, auditory training leads to improvement in speech-in-noise perception, but these studies did not consider the etiology, so their results cannot be generalized. The present study aimed at investigating the effectiveness of envelope-b...

This paper describes speech translation from Amharic-to-English, particularly Automatic Speech Recognition (ASR) with post-editing feature and AmharicEnglish Statistical Machine Translation (SMT). ASR experiment is conducted using morpheme language model (LM) and phoneme acoustic model (AM). Likewise, SMT conducted using word and morpheme as unit. Morpheme based translation shows a 6.29 BLEU sc...

Phone-like units (PLUs) for automatic speech recognition are derived using a decision tree algorithm. In our approach we use information such as target phone label, immediate context, lexical stress level and function word affiliation in the decision tree analysis. The resulting PLUs are shown to improve phone and word recognition.

This paper investigates the relationship between the word accuracy and the PESQ (ITU-T Recommendation P.862) score, and the availability of the artificial voice (ITU-T Recommendation P.50) for calculating the PESQ score. For this purpose, recognition experiments using four noise reduction algorithms were performed on the AURORA-2J connected digit recognition task. These results confirmed that t...
