Firstly, we study the construction of emotion - speech template database, and analyze the common features such as pitch, energy and formant. after choosing the useful features by using fuzzy entropy effectiveness analysis, we get better performance with the application of neural network. in addition, we propose some more efficient features such as speech rate, pitch slope, mel - frequency cepstral coefficients and its transient parameters, and design a processing model based on vector quantization for cepstral features to fusing different features
本文首先介紹了情感語音數據庫的建立情況，然後研究了基音頻率、振幅能量和共振峰等目前常用的情感特徵在語音情感識別中的作用，並且通過一種基於模糊熵的特徵有效性分析方法進行了有效特徵的篩選，應用人工神經網路建立了初步的語音情感識別模型，經過實驗發現特徵篩選后系統的識別效果有著一定程度的提高。 -

Starting from the basic concept for the production of musical sound, the essay reduces the sound to its single tone, analyzes the common origins of pitch, rhythm and volume on the deeper level, and thereby derives the potential of the transformation among the three, revealing the truth in the art of music that the whole is not equal to the simple addition of all individuals
本文從音樂音響產生的基本概念入手，將音響還原到單音狀態，分析了音高、節奏、音量在深層次上的共同根源，並以此推導出三者存在相互轉化的可能，從而揭示在音樂藝術中整體並不等同於單個個體的簡單相加，而二度創作空間從單音的發音到分句的劃分也同樣存在無窮的可能，也由此決定了人的感性參與的重要意義，它們的創作空間是主客觀的共同作用。
