| Updated voice content description |
| This module has a built-in USB interface, which can flexibly replace the voice content in SPI-flash, eliminating the trouble of installing a host computer to replace the voice of the traditional voice chip. SPI FLASH is directly simulated into a USB flash drive, just like copying a USB flash drive, which is very convenient. Any computer system can support it, while other ordinary copywriting can only support XP and WIN7 system voice update. |
| Connect the module with a USB data cable and plug it into the computer, the computer will automatically recognize it, as shown in the figure below: |
| Then double-click the new disk and copy the sound you want to place there. |
