Relative Weights of Temporal Envelope Cues in Different Frequency Regions for Mandarin Vowel, Consonant, and Lexical Tone Recognition.

Mandarin-speaking users of cochlear implants (CI) perform poorer than their English counterpart. This may be because present CI speech coding schemes are largely based on English. This study aims to evaluate the relative contributions of temporal envelope (E) cues to Mandarin phoneme (including vowel, and consonant) and lexical tone recognition to provide information for speech coding schemes specific to Mandarin.

The Relative Weight of Temporal Envelope Cues in Different Frequency Regions for Mandarin Disyllabic Word Recognition.

Objectives: Acoustic temporal envelope (E) cues containing speech information are distributed across all frequency spectra. To provide a theoretical basis for the signal coding of hearing devices, we examined the relative weight of E cues in different frequency regions for Mandarin disyllabic word recognition in quiet.

Design: E cues were extracted from 30 continuous frequency bands within the range of 80 to 7,562 Hz using Hilbert decomposition and assigned to five frequency regions from low to high.

Steroid Administration Approach for Idiopathic Sudden Sensorineural Hearing Loss: A National Survey in China.

Objective: To optimize a protocol for the steroid administration approach for idiopathic sudden sensorineural hearing loss (ISSNHL) in China.

Methods: A questionnaire was distributed to otolaryngologists. The data on demographics, indications for first-line and salvage treatment, such as intratympanic administration of steroids (ITS) and postauricular steroids (PAS), and procedures were analyzed.

Establishment of an induced pluripotent stem cell line from a patient with CHARGE syndrome carrying a CHD7 (p.L1151Gfs*17) mutation.

CHARGE syndrome is a rare disease caused by a genetic disorder. The clinical features of this syndrome include coloboma of the eye, heart anomaly, choanal atresia, retardation of mental and somatic development, microphallus, ear abnormalities and/or deafness. CHD7 is the main causative gene for CHARGE syndrome.
