Getting Started

Install and experience it!

The current system only has Japanese models for speech processing, so the default contents are in Japanese language only. We actually has an English speech model assets already, and are now working to make English version.


MMDAgent-EX runs on various platform: iOS, Android, Windows, Mac OS and Linux.

On desktop OS, Audio input device is required. MMDAgent-EX will open the default audio device for audio input.

MMDAgent-EX will use at least 300 MBytes of disk space for system. On desktop OS, all the downloaded files are stored under user’s home or desktop directory.

Network connection is required. MMDAgent-EX will first download the system data from Web.

To make speech recognition work better, avoid using this app in a very noisy environment.
