This is an addon for Blender that lets you automatically generate lip-synced data from audio tracks. It can be used for both 2D and 3D animations and supports many common languages. It uses OpenAI's Whisper library to turn spoken audio tracks into words, and then Gruut to turn words into phonemes to create the key frames for your mouth positions.

This addon requires some additional setup in addition to just installing it through the addons menu, so please read the installation section carefully.

At present, it does not provide support for east Asian languages that use kanji due to a lack of support in the phonemizing libraries. Hopefully this will change in the future as the Python libraries Parrot relies upon improve.

This addon can also be downloaded from its Github page. Please post any errors you encounter there.

Installation

Parrot Lipsync relies on you having some other applications already installed on your computer.

Install Ffmpeg

Ffmpeg is a popular library that lets you read and write many popular media files. It needs to be accessible from the command line.

Open a command prompt and type the following to see if it is already installed:

ffmpeg -version

If ffmpeg has not been found, you will need to install it.

# on Ubuntu or Debian
sudo apt update && sudo apt install ffmpeg
# on Arch Linux
sudo pacman -S ffmpeg
# on MacOS using Homebrew (https://brew.sh/)
brew install ffmpeg
# on Windows using Chocolatey (https://chocolatey.org/)
choco install ffmpeg
# on Windows using Scoop (https://scoop.sh/)
scoop install ffmpeg

Installing the Parrot Lipsync addon

Now that ffmpeg is installed, you can install Parrot by opening the `Edit > Preferences > Addons` window and clicking the `Install` button. Browse to the Parrot Lipsync zip file you downloaded and select it. Finally, make sure the check mark next to `View 3D: Parrot Lipsync` is checked so that the addon is activated.

Install Whisper and Gruut

Parrot needs some support libraries to function. The easiest way to install them is to open Parrot's configuration page in the `Addon` window to reveal the buttons on the bottom. Press the `Install whisper_timestamped` and `Install gruut` buttons to ensure these necessary libraries are added to your Blender's python packages. Some languages will require an additional package - for example, if you intend to use the Russian language, make sure to click the `Install gruut-lang-ru` button as well.

Alternate installation procedure for Whisper and Gruut

It is also possible to install Whsiper and Gruut on the command line as well if you don't want to use the installation panel.

Open a terminal window and go into your Blender installation's python directory (on Windows it should be something like `C:\Program Files\Blender Foundation\Blender 4.0\4.0\python\bin`). Then issue the following commands:

./python.exe -m pip install --upgrade whisper_timestamped
./python.exe -m pip install --upgrade gruut

For MacOS and Linux, the following should work:

./python -m pip install --upgrade whisper_timestamped
./python -m pip install --upgrade gruut

Some languages will require additional packages to be installed:

Russian:

./python.exe -m pip install --upgrade gruut-lang-ru

Usage

I've put together a video describing how you can use Parrot to lip sync characters in your animations.

Editing the Phoneme Table

Parrot Lipsync uses a separate JSON file which defines what mouth positions to use and which phonemes are used for which mouth positions. By default it will use the file named `phoneme_table_en.json` which comes with the addon. This file can be edited to change which mouth position groups are used and which phonemes should be used for each mouth position.

If you wish to define your own phoneme table, it is recommended that you make a copy of `phoneme_table_en.json`, add your customizations to it and then set the `Phoneme table file` field of the Parrot UI to point to your custom file.

Description of the Phoneme table

The phoneme table has two main sections:

The `groups` section defines each mouth position that your animation will use. The groups are what you will assign mouth poses to in the addon UI. The `name` field defines the name of the group and the `description` field lets you add some descriptive text to explain to the user what sounds this mouth pose is meant to make (and which is displayed as a hint). The groups will also always include a special group called `rest`, even if you do not explicitly define it in the JSOn file. The `rest` group is meant to represent the mouth when it is closed between words.

The `phonemes` section is where you let Parrot know which phoneme symbols belong to which group. The `code` field is the International Phonetic Alphabetic code for the syllable and the `group` field indicates which mouth pose group the syllable belongs to. The `class` and `example` fields are not currently used by Parrot but meant to provide usage hints to the user and might be used in a future version of Parrot.
