查询词典 vocoder

SELP is based on linear prediction analysis, but adopts a totally different speech excitation model from traditional LPC vocoder.

SELP基于线性预测分析，但采用了完全不同于传统LPC声码器的激励模型。

In general, two half-rate vocoder frames ( 201 and 202 ) are assembled into a single full rate transmit frame ( 200 ) to enable the transmission of alternating full-rate frames.

通常，两个半速率声码帧(201和202)组装成一个全速率传输帧(200)，用以能够传输交变全速率帧。

This thesis intends to improve the performance of IMBE speech vocoder under noisy enviroment by the combination of speech enhancement techniques with the MBE speech model.

我们研究了两种方案：一是采用语音增强预处理器和IMBE声码器级联，二是将语音增强技术和IMBE声码器有机结合构成语音增强IMBE声码器。

A feature extraction method is designed for linear predict vocoders widely used in the communication field. In this method, feature vectors are extracted not from the decoded waveform, but from the bit stream of transmission directly. Specifically for Wideband Adaptive Multi Rate vocoder, we implemented a text-independent speaker verification system.

面向通信领域广泛使用的线性预测声码器，设计了一种不经过&解码－特征提取&过程，而直接由传输码流截取说话人特征的方法，并针对宽带自适应多码率声码器建立了与文本无关的话者确认系统。

Innovations and improvements in the algorithms are mainly included as: 1 The phonetic classification algorithm is applied into the Sinusoidal Model based coding scheme, the speech characteristics in Mandarin are utilized, so the coding rate of the vocoder is reduced, speech quality is maintained, and the flexibility in designing vocoders is improved.

在对算法的研究上，主要的创新和改进表现在以下几个方面： 1）将分类算法应用到其于正弦模型的编码算法中，并利用汉语的语言特点，使声码器总的码率得到降低，音质得到保持，同时使声码器设计上的灵活性得到提高。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
