摘要

如今，互联网上有500多篇免费的《古兰经》经文。大多数音频文件都是用MP3格式录制的，因为它很受欢迎，但无损音频编码由于其高质量而获得了很多兴趣。无损音频编码的缺点是对比特率的要求较高。本文对古兰经各诵经者诵读古兰经的特点进行了评价。结果表明，古兰经诵读的浊音与浊音之比平均为21.39，而英语有声读物的浊音与浊音之比平均为7.49。这意味着在古兰经背诵中，浊音比浊音更占优势。期望进一步优化典型无损音频压缩中的线性预测分量，从而实现对古兰经音频信号的高效表示。

On the Characteristics of Various Quranic Recitation for Lossless Audio Coding Application

Nowadays, there are more than 500 Quranic recitations available freely on the internet. Most of the audio files were recorded in MP3 format due to its popularity, but lossless audio coding has gained much interest due to its high quality. The drawback of the lossless audio coding is the higher bitrate requirement. In this paper, the characteristics of the Quranic recitation of all surahs from various Reciters were evaluated. Results show that on average the voiced to unvoiced speech ratio is 21.39 for Quranic recitation, while the English audiobook on average has ratio of 7.49. It means that the voiced speech is more dominant compared to unvoiced speech in Quranic recitation. It is expected that the linear predictor component in a typical lossless audio compression could be optimized further so that efficient representation of Quranic audio signal could be achieved.
