Dialogic的vox语音格式实际上是一种ADPCM编码，与ITU的G.726 ADPCM算法非常类似。由于ITU的G.726算法比较复杂，实际应用中，多半采用该算法的变体实现。各种变体的区别主要在于参数不同。Dialogic采用的是OKI的一 种实现，称为OKI ADPCM。Windows的.wav格式也包括OKI的ADPCM。-the vox Dialogic voice format is actually a ADPCM encoding, with the ITU G.726 ADPCM algorithm is very similar. As the ITU G.726 algorithm complexity, the actual application, and most of the use of the algorithm to achieve variant. Variants of the various major difference lies in different parameters. Dialogic is the realization of a Sound, known as OKI ADPCM. Windows. Wav format also includes Sound of ADPCM.
