Modeling of Accent Perception in Chinese Spontaneous Speech
نویسنده
چکیده
The accent was proved to be the essential links between linguistics and acoustics, and behaves as an important parameter for prosody processing and unit selection in speech synthesis system. In the paper, some acoustical measurements are carried out on F0, duration, silence in order to disclose the relationship between accent and corresponding acoustical parameters. The normalized acoustic parameters are induced to facilitate the accent detecting. Based on this, a model is proposed to predict accent in spontaneous speech. The method is proved to be very successful and has been used to label accent automatically for our large corpus. Further listening tests also show that the labelling results reaches 86% accurate rate, which is nearly the same as the agreement of hand labelling results. Furthermore, different native’s evaluations are also compared in the paper.

Perception of Nonnative Accent: A Cross-Sectional Perspective Pilot Survey
Accent bias is a consequence of ethnocentrism. No studies have examined accent bias across educational levels in the U.S., much less across students and professionals in speech language pathology (SLP), a field that requires multicultural sensitivity training. This study examines nonnative accent perception among three groups—high schoolers, SLP students, and SLP professionals. One-hundred-and-...
متن کاملStrong influence of prosody on the perception of foreign accent
This study investigates the acoustic characteristics of non-native speech which give rise to the perception of a foreign accent. Japanese speech samples were collected from L1 English and Mandarin speakers studying Japanese. The acoustic patterns of the L2 and native speech were related to the accentedness ratings of the speech provided by native Japanese listeners. Results indicate the importa...
متن کاملMulti-accent Chinese speech recognition
Multiple accents are often present in spontaneous Chinese Mandarin speech as most Chinese have learned Mandarin as a second language. We propose a method to handle multiple accents as well as standard speech in a speaker-independent system by merging auxiliary accent decision trees with standard trees and reconstruct the acoustic model. In our proposed method, tree structures and shape are modi...
متن کاملImproving ASR performance on non-native speech using multilingual and crosslingual information
This paper presents our latest investigation of automatic speech recognition (ASR) on non-native speech. We first report on a non-native speech corpus an extension of the GlobalPhone database which contains English with Bulgarian, Chinese, German and Indian accent and German with Chinese accent. In this case, English is the spoken language (L2) and Bulgarian, Chinese, German and Indian are the ...
متن کاملA Syllable, Articulatory-feature, and Stress-accent Model of Speech Recognition
Current-generation automatic speech recognition (ASR) systems assume that words are readily decomposable into constituent phonetic components (\phonemes"). A detailed linguistic dissection of state-of-the-art speech recognition systems indicates that the conventional phonemic \beads-on-a-string" approach is of limited utility, particularly with respect to informal, conversational material. The ...
