VP-880 is a voice development tool that provides installation and operation manual for a speech development system.
This manual describes the hardware and software requirements for the VP-880 voice development system, including compatible PC models, memory, and disk space. It also lists the contents of the distribution disks and explains how to install the software using the provided batch file.
The document then details the operation of the VP-880, covering the main menu, sample‑rate testing, speaker control, recording, playback, file loading/saving, segment editing, ROM bank development, and EPROM programming. This manual is written in Chinese.

Insert the system disk, then at the DOS prompt type the INSTALL command, for example "INSTALL C:\VP880" to copy the files to the C: drive.
After installation, navigate to the VP-880 directory and type "880" (or "880 /IRQ=X /IOPORT=NNN" to specify IRQ or I/O port).
Use the variable resistor VR3 on the VP-880 card; turning it clockwise raises the sample rate, counter‑clockwise lowers it.
