本文的研究目的是探索韵律信息在语言识别和辨别任务中的应用。本研究的目的是通过一个感知实验来考察韵律模式是否可以作为区分阿拉伯方言的可靠声学线索。实验中，当听者仅能获得原始语音信号的基频、振幅和某些节奏特征时，他们是否能成功地识别出说话人所使用的阿拉伯方言。结果表明，韵律线索单独可以区分方言对，因为母语阿拉伯听众是显着更成功地识别阿拉伯方言品种在其自然和合成的形式和听众的识别率更高的歧视自己的方言品种时，根据其处理形式。这种感知研究必须被视为第一步，确定一套可靠的线索，自动识别阿拉伯语方言。
The aim of the work to be reported here is to explore the utility of prosodic information in language identification and discrimination tasks. The purpose of this study is to see whether prosodic patterns can be considered as reliable acoustic cues for the discrimination of Arabic dialects by investigating, via a perceptual experiment, if listeners are successful in identifying the Arabic dialect used by a speaker when they only have access to fundamental frequency, amplitude and some rhythmic characteristics of the original voice signal. Results show that prosodic cues alone can distinguish between dialect pairs, since native Arabic listeners are significantly more successful in identifying the Arabic dialectal varieties both in their natural and synthesized forms and that listeners’ identification rate are higher for the discrimination of their own dialectal variety when presented under its processed form. This perceptual study must be regarded as a first step towards the determination of a set of reliable cues for the Automatic Identification of Arabic Dialects.
