Envelope expansion of sine wave vocoded speech

2011-01-01 The Journal of International Advanced Otology, 2011, Vol 7(3), 391-397. Arivudai P Nambi Jayashree S Bhat Somashekara H S

Objective: Present study investigated the effect of envelope expansion on sine wave vocoded speech. Speech recognition score for sine wave vocoded stimuli was assessed in quiet as well as in presence of background noise. Materials and Methods: The test stimuli consisted of four lists, each containing ten HINT (Hearing in noise test) sentences spoken by a female speaker, subsequently each of these stimulus sentences were divided into 8 frequency bands and an envelope was extracted from each frequency bands at 400Hz cut off. Envelope was expanded using overlap and add algorithm (OLA) at the modulation frequencies from 1 to 30 Hz. Ten adult individuals participated in the perceptual task. Results: Speech recognition scores in the presence of background noise was significantly poor when compared to speech recognition in quiet Paired't' test revealed no significant main effect of envelope expansion on speech recognition in quiet as well as in noise. Conclusion: Envelope cues alone are sufficient for good speech recognition in quiet but not in the presence of noise. Envelope expansion scheme does not affect the sentence perception containing only envelope cues in quiet as well as in noise.

Relationship between phonological awareness and reading abilities in typically developing Malayalam speaking children

The article presents the result of a study which examined the relationship between phonological awareness and reading skills within the context of children who speak Malayalam. The researcher used the variables of rhyme recognition, syllabic stripping, syllable reversal and phoneme detection to evaluate skills relating to phoneme awareness, phonological memory and phonological naming in Malayalam. The mean reading performance children is assessed.

Contribution of frequency modulations to the perception of spectrally shifted speech in quiet and noise

Cochlear implant is electronic device which is surgically implanted into the cochlea to provide the sense of hearing for hearing impaired individual who may not benefit from hearing aids. The current day’s cochlear implant codes only the temporal envelope cues. Speech perception simulation studies have shown that, adding frequency modulation cues to the amplitude modulation improves the speech recognition under adverse listening condition. A similar processing cannot be incorporated in the cochlear implant as it would result in spectral mismatch. The current study evaluated the effect of such mismatch on speech recognition scores. Method: The study involved the subjects with normal hearing who listened to the spectrally shifted HINT sentences having only amplitude modulation (AM) cues and amplitude modulation with frequency modulations (FM). Sine wave vocoders were used to synthesize the signals with only AM and AM with FM cues. For simulating the spectral mismatch, carrier frequencies were decided based on Greenwood’s map. Sine wave vocoded speech was presented with and without background noise. Results: Paired‘t’ test showed significant main effect of FM on spectrally shifted speech in quiet as well as noise. Mean scores significantly improved when the speech was processed with AM+FM spectral shift than AM spectral shift alone in both the conditions. Conclusion: The results of the current study indicated the importance of frequency modulation cues even in the spectrally mismatched conditions.

Comparison of Phonological Awareness Skills in Children in English with Diverse Native Languages

2016-06-07 International Journal of English & Education, 2016, Vol 5(3), Pg 88-102 Somashekara H S Jayashree S Bhat Ananya A

The children in multilingual education system often learn to read a language that is not spoken at home for many reasons. Even, the child’s L1 and L2 may be distinct in phonological and orthographical structure. The question on relative advantage of child’s native language on L2 phonological acquisition is unclear. The present study compared phonological awareness skills of primary school children learning English with varied alpha syllabic native language (L1) background. The phonological awareness skills were assessed in 20 typically developing children each from 5 different native languages such as Kannada, Tulu, Konkani, Telugu and Malayalam. These children are designated as English language learners, since they were studying in primary school with English as a medium of instructions within the age range of 8.7 – 9.6 years. Children were divided into five groups based on the native language which was ascertained by questionnaire administered on parents. Subsequent comparison of phonological awareness skills between all the five groups using ANOVA revealed no significant difference in the performance between the language groups. The study concluded that, irrespective of alphasyllabary native language spoken at home, had no relative advantage in acquiring phonological awareness skills in English learnt as a second language in primary school
