Description: 争对移动声源采用波束形成进行语音增强,提出一种约束子带波束形成算法。其波束形成器基于一个软约束,其目的是要使波束指向特定的区域即声源方向。而其核心在于首先要进行声源定位,获得尽量准确的方位信息,然后构造软约束条件,用于波束形成。且在此过程中不断跟踪声源的移动情况。在构造的约束条件中,需要知道声源的二维信息,即与麦克风阵列的距离和方向角,“软”体现在对距离和方向角的确定都是在一定范围内的,有待进一步更正。-Between the mobile sound source using beamforming for speech enhancement, a constrained subband beamforming algorithm. Its beamformer based on a soft constraints, the aim is to make the beam point to a specific region that is the direction of the sound source. And its core is the first to sound source location, access to location information as accurately as possible, and then construct the conditions of soft constraints for beamforming. And in the process continuously tracking the movement of a sound source. Structure at the binding conditions, need to know the two-dimensional sound source information, that is, with the microphone array the distance and direction angle, the " soft" embodied in the distance and direction angle of the determination are within the scope must be further corrected .

Description: 一种简单有效的基于动态时变语音识别源码
对于大多数研究者来说,寻找能够匹配二重时间序列信号的最佳途径是很重要的,因为它有许多重要的应用需求.DTW是实现这项工作的显著技术,尤其在语音识别技术领域,在这里一个测试信号被按照参照模板拉伸或压缩,
-Searching for the best path that matches two time-series signals is the main task for many researchers, because of its importance in these applications. Dynamic Time-Warping (DTW) is one of the prominent techniques to accomplish this task, especially in speech recognition systems. DTW is a cost minimisation matching technique, in which a test signal is stretched or compressed according to a reference template.
Although there are other advanced techniques in speech recognition such as the hidden Markov modelling (HMM) and artificial neural network (ANN) techniques, the DTW is widely used in the small-scale embedded-speech recognition systems such as those embedded in cell phones. The reason for this is owing to the simplicity of the hardware implementation of the DTW engine, which makes it suitable for many mobile devices. Additionally, the training procedure in DTW is very simple and fast, as compared with the HMM and ANN rivals.

Description: 关于语音处理的英文书籍,其中特征提取部分(MFCC)讲解的很好很详细-The performance of speech recognition systems receiving speech that has been transmitted over mobile channels can be
significantly degraded when compared to using an unmodified signal. The degradations are as a result of both the low
bit rate speech coding and channel transmission errors. A Distributed Speech Recognition (DSR) system overcomes
these problems by eliminating the speech channel and instead using an error protected data channel to send a
parameterized representation of the speech, which is suitable for recognition. The processing is distributed between the
terminal and the network. The terminal performs the feature parameter extraction, or the front-end of the speech
recognition system. These features are transmitted over a data channel to a remote "back-end" recognizer. The end result
is that the transmission channel does not affect the recognition system performance and channel invariability is achieved. Platform: |

Description: The voice channel in mobile communication systems have high priority and are
almost always available. By using the voice channel also for data transmissions it
is possible to get the same availability as for voice calls. But due to speech codecs
in the voice channel, regular modems can not be used and special techniques are
needed to transmit data.
This thesis presents methods to transmit data over the voice channel in a GSM,
UMTS or TETRA network. The focus has been on robust data transmission rather
than high data bit rates. Approaches are introduced which improve the reliability
for transmissions even for systems with low rate speech codecs and channels with
some distortion.
The results of the thesis are suggestions of symbol patterns and ways to create
and adapt symbols for specific application and channel conditions to achieve the
desired goal for the application Platform: |

everyday applications. A robust speech-recognition system combines accuracy
of identification with the ability to filter out noise and adapt to other acoustic
conditions, such as the speaker’s speech rate and accent. Designing a robust
speech-recognition algorithm is a complex task requiring detailed knowledge of
