Description: simple implementation of dynamic time warp alignment between soundfiles. In addition to using this for scoring the similarity between sounds, we can also use it to `warp a soundfile to match the timing of a reference, for instance to synchronize two utterances of the same words.-simple implementation of dynamic time warp alignment between soundfiles.

Description: Detailed description about Dynamic time warping, which is a popular algorithm in audio signal processing and recognition. In this documents, basic DTW algorithm is discussed and a few important charactors of the algorithm is pointed out. The common belief in DTW algorithm is not entirely true, and may leads to false system design. Although DTW is widely used in audio signal processing, it may also be used in DNA serrals

Description: 在孤立词语音识别中，最为简单有效的方法是采用DTW（Dynamic Time Warping，动态时间归整）算法，该算法基于动态规划（DP）的思想，解决了发音长短不一的模板匹配问题，是语音识别中出现较早、较为经典的一种算法，用于孤立词识别。HMM算法在训练阶段需要提供大量的语音数据，通过反复计算才能得到模型参数，而DTW算法的训练中几乎不需要额外的计算。所以在孤立词语音识别中，DTW算法仍然得到广泛的应用。-Isolated word speech recognition, the most simple and effective method is to use DTW (Dynamic Time Warping, Dynamic Time Warping) algorithm based on dynamic programming (DP) of thinking to solve the problem of template matching pronunciation of varying lengths, is earlier, more classic kind of speech recognition algorithm appears for isolated word recognition. HMM training phase algorithm needs to provide a large amount of speech data, by repeatedly calculating the model parameters can be obtained, and DTW algorithm training almost no additional computation. Therefore, in isolated word speech recognition, DTW algorithm is still widely used.

Description: 于市售 STM32 开发板上实现特定人语音识别处理项目。识别流程是：预滤波、ADC、分帧、端点检测、预加重、加窗、特征提取、特征匹配。端点检测(VAD)采用短时幅度和短时过零率相结合。检测出有效语音后，根据人耳听觉感知特性,计算每帧语音的 Mel 频率倒谱系数(MFCC)。然后采用动态时间弯折(DTW)算法与特征模板相匹配,最终输出识别结果。先用Matlab对上述算法进行仿真，经数次试验求得算法内所需各系数的最优值。而后将算法移植到 STM32 开发板上，移植过程中根据 STM32 上存储空间相对较小、计算能力也相对较弱的实际情况，对算法进行优化。最终完成于 STM32 微处理器上的特定人语音识别系统。-Implement speech recognition processing project in commercially available STM32 development board. Identification is the process: pre-filter, ADC, framing, endpoint detection, pre-emphasis, windowing, feature extraction, feature matching. Endpoint detection (VAD) short-time amplitude and short-term zero rate combined. After detecting an effective voice, according to the characteristics of human auditory perception, calculated for each frame of speech Mel Frequency Cepstral Coefficients (MFCC). Then dynamic time warping (DTW) algorithm and feature template matches the final output recognition result. First with Matlab simulation algorithm described above, after several trials to get the optimal value of each coefficient within the desired algorithm. The algorithm will migrate to STM32 development board, the porting process according to the STM32 relatively small storage space, computing power is relatively weak situation of the optimization algorithm. Finally completed on the STM32 micr
