AI voice changer `` Koemake RVC Player '' review that can convert free & voice in real time

The open source AI voice changer ``

Retrieval-based Voice Changer (RVC) '' can create a learned model from pre-prepared voices and convert voice quality in real time. DendenMei has released a voice changer software `` Koemake RVC player '' that can easily execute the voice conversion model created with this RVC, so I actually tried using it.

Unzip the downloaded ZIP file with decompression software such as

Explzh or the standard function of Windows. Start 'koemake.exe' in the folder. In addition, it takes about 1 minute to start up only when starting up for the first time.

When you start Koemake RVC Player, it looks like this. At the time of article creation, Koemake RVC Player is equipped with the RVC model learned by ``

Tsukuyomi-chan Corpus '' by default. You can select the input device with 'Input I/F' at the bottom left, and the device that outputs converted audio with 'Output I/F'.

You can change the parameter of how much to fit the target voice with 'Index Rate', the pitch of the voice after conversion with 'Key', and the volume of the voice after conversion with 'Vol'. Adjust the three slide bars while speaking into the microphone. According to the Kaomake RVC Player

usage page , the recommended Key setting is +12 when converting from male to female voice, -12 when converting from female to male voice, and 0 for same-sex voice.

You can see what happens when you actually convert the voice with Koemake RVC Player by watching the following movie. In the movie, read the opening part of Soseki Natsume's '

I am a cat ' with 'Voice before conversion', 'Voice converted by setting Key = +12', and 'Voice converted by setting Key = -5' doing. The PC used for the review was equipped with ASUS Dual RTX3060 VRAM 12GB , and there was a lag of about 1 second from the time the voice was blown into the microphone until the converted voice was output.

When you actually listen to it, you can see that when converting from a male voice to a female voice, setting the Key to +12 can convert the voice quite naturally. When I set the Key to -5, it turned out to be a bit too low. In addition, Koemake RVC Player does not require any complicated settings, it can be converted just by starting it, setting the device and speaking, and there are only 3 parameters for adjustment, so even beginners can use it easily. .

At the time of article creation, Tsukuyomi's RVC model is built in, but it is also possible to load the RVC model prepared by yourself. In addition, ``Denden Mei'' and ``Todoroki Jin'' are scheduled to be added as learning models for the Koemake Project.
