Vocaloid-flex
Yamaha developed Vocaloid-flex, a singing software application based on the Vocaloid engine, which contains a speech synthesizer. According to the official announcement, users can edit its phonological system more delicately than those of other Vocaloid series to get closer to the actual speech language; for example, it enables final devoicing, unvoicing vowel sounds or weakening/strengthening consonant sounds. It was used in a video game Metal Gear Solid: Peace Walker released on April 28, 2010. It is still a corporate product and a consumer version has not been announced. This software was also used for the robot model HRP-4C at CEATEC Japan 2009. Gachapoid has access to this engine and it is used through the software V-Talk.

VocaListener
Another Vocaloid tool that was developed was VocaListener, a software package that allows for realistic Vocaloid songs to be produced.

Miku Miku Dance
To aid in the production of 3D animations, the program MikuMikuDance was developed as an independent program. The freeware software allowed a boom in fan-made and derivative characters to be developed, as well as acted in a boost for the promoting of the Vocaloid songs themselves. As of May 2011, no more updates to Miku Miku Dance are being released.

NetVocaloid
NetVocaloid is an online vocal synthesis service. Users can synthesize singing voices on a device connected to the Internet by executing the Vocaloid engine on the server. This service can be used even if the user does not actually own the Vocaloid software. The service is available in both English and Japanese.

MMDAgent
MMDAgent is a software developed by the International Voice Engineering Institute in the Nagoya Institute of Technology, and the Alpha version was released on December 25, 2010. This particular software allows users to interact with 3D models of the Vocaloid mascots. The software is made from 3D models and sound files that have already been made available on the internet and will be disputed as freeware for that reason.

NetVocalis
NetVocalis is a software being developed by Bplats, makers of the VY series, and is similar to VocaListener.
