Well, I got this module out of curiosity from eBay - just wanted to see how a Chinese speech recognition IC works. I cannot speak Chinese either - that's why I have to test using Chinese proper names which I can pronounce. Turned out it works fairly well. However what annoyed me was the wrong pinout printed on the PCB, causing me to waste several days debugging the issue - the labels of almost all communication pins on the left connection header are reversed, RSTB should be INTB, CLK should be WRB and vice versa! (The image of the board attached in my previous post is the image after being edited with Paint to show the correct pinout)
I am not sure why there should be this issue, knowing that the VCC and GND pins are correctly labelled.
A detailed writeup, with a description of the PCB issue, and the MPLAB X source code, can be found on my blog
