语音转喻探究

语音隐喻概念首先是由匈牙利语言学家Fónagy提出的,李弘对这一语言现象进行了较为详细的描述、分类和实例分析。通过对李弘论文实例的重新分析,可以发现,该文中所涉及的多数语言现象可以归纳为语音转喻,即一个词语利用谐音转指另一个词语。语音转喻的认知机制源于概念转喻,它所涉及的并非概念域而是语音域。语音转喻可大致分为两种:同音异义词和语音仿拟。

AMR与G.729之间的转码算法

提出了AMR与G.729语音编码标准之间的2种新型转码算法——索引域转码算法和语音域转码算法.它们分别针对具有相同和不同固定码本结构的语音编码标准进行转码.索引域转码算法直接对2个编码的索引值进行相互转换;语音域转码算法则需要在语音域重新对转换的固定码本及增益进行搜索.实验结果表明,这2种转码算法都能有效地降低转码复杂度,语音域转码算法的算法复杂度仅为传统Tandem转码的55%左右,而索引域转码算法的算法复杂度则不到Tandem转码的10%.同时,索引域转码算法的语音质量相对Tandem转码有所提高,而语音域转码算法则保持了约略相当的语音质量.

Study of accent differences among regional varieties of English

The globalization and nativization processes of English resulted in the appearance of a large number of regional varieties of English. Concerning their accent between the single norm theory and the multiple norm differences, there has always been a debate theory. This paper argues against the ＇standard-nonstandard＇ classification of English accents upheld by the former, and revises the concept of ＇the three concentric circles of English＇ proposed by the latter, providing some helpful tips on the current instruction of listening and speaking in China＇s colleges and universities.
