PURPOSE To investigate the effect of listener's native language (L1) and the types of noise on English vowel identification in noise. METHOD Identification of 12 English vowels was measured in quiet and in long-term speech-shaped noise and multi-talker babble (MTB) noise for English- (EN), Chinese- (CN) and Korean-native (KN) listeners at various signal-to-noise ratios (SNRs). RESULTS Compa...

This paper presents the WordFrame model, a noiserobust supervised algorithm capable of inducing morphological analyses for languages which exhibit prefixation, suffixation, and internal vowel shifts. In combination with a näive approach to suffix-based morphology, this algorithm is shown to be remarkably effective across a broad range of languages, including those exhibiting infixation and part...

OBJECTIVE Everyday life includes fluctuating noise levels, resulting in continuously changing speech intelligibility. The study aims were: (1) to quantify the amount of decrease in age-related speech perception, as a result of increasing noise level, and (2) to test the effect of age on context usage at the word level (smaller amount of contextual cues). PATIENTS AND METHODS A total of 24 you...

Vowel quality perception in quantity languages is considered to be unrelated to vowel duration since duration is used to realize quantity oppositions. To test the role of microdurational variations in vowel category perception in Estonian listening experiments with synthetic stimuli were carried out, involving five vowel pairs along the close-open axis. The results show that in the case of high...

Consonant-vowel (CV) perception experiments provide valuable insights into how humans process speech. Here, two CV identification experiments were conducted in a group of hearing-impaired (HI) listeners, using 14 consonants followed by the vowel /ɑ/. The CVs were presented in quiet and with added speech-shaped noise at signal-to-noise ratios of 0, 6, and 12 dB. The HI listeners were provided wi...

Sensorineural hearing loss causes reduction in frequency resolving capacity of the ear due to spread of masking of frequency components by adjacent frequency components. We have carried out experimental evaluation of splitting speech into two complementary signals on the basis of frequency and presenting it binaurally for increasing the speech intelligibility. In this scheme, input speech signa...

Recently we reported that talkers modified their speech production strategies in noise as a function of whether their interlocutor could or could not be seen, i.e. face-to-face (FTF) or non-visual conditions (NV). Participants made greater auditory speech modifications (e.g. in terms of amplitude and F0) in NV condition, and greater visual speech modifications (in terms of inter-lip area) in FT...
