v0.12.0 - SDK Example Scene

This release includes a simple blueprint based example scene that can be used as a basis for Charisma implementation in your own projects.

The Plug-n-Play still has its own example implementation, although this one is simpler.

Full Changelog: v0.11.1...v0.12.0

v0.11.1 - uPlugin Cleanup

This release contains a small clean-up of the uPlugin file. No developer facing changes.

Full Changelog: v0.11.0...v0.11.1

v0.11.0: UE 5.3 support!

This release adds support for Unreal Engine 5.3!

Note: The msgpack implementation needed to change significantly to keep the compiler happy, so please report any issues here.

v0.10.0: Mac support

This release adds Mac support!

v0.9.0: Unified speech recognition, multiple TTS encoding support

• Adds the unified speech recognition API. See https://charisma.ai/docs/sdks/speech-recognition for more details.
• Multiple text-to-speech encodings can now specified as an array, to support more voice services out the box.
• Fixes an issue using the Actor component when no audio was generated by Charisma.

v0.7.2: UE5.2 support

• Ensured compilation on UE5.2.
• Connection state handling has been refactored: OnConnect and OnReady have been removed as Playthrough events, and OnChangeConnectionState has been added.
• PlaythroughEventsManager, which provided AttachPlaythroughHandlers has been removed. Instead, bind to the events directly on the Playthrough object.

v0.6.0: Unreal Marketplace launch!

In this release, Charisma is now available on the Unreal Marketplace! 🎉

To download, head to: https://www.unrealengine.com/marketplace/en-US/product/charisma-conversational-ai-for-npcs

Other improvements:

• Added Pause and Play Blueprint nodes to pause/play a Charisma playthrough, useful for pause screens in-game.
• Improved logging implementation: all logs are now made under the custom Charisma category.
• Added language code to speech recognition.
• Added experimental Reset Playthrough Blueprint node.
• All references to EventIds are now strings instead of int64s to align with the type sent from Charisma.

v0.5.0: Speech recognition

This release adds support for speech recognition directly into Charisma! 🎉

To enable this for your story, please get in touch with us.

Also, this release:

• Adds a Fork Playthrough node to upgrade players to the latest published version of the story
• Adds a ping/pong mechanism to detect disconnections earlier

v0.4.0: Refactor voice clip decoding

The custom functions decoding the audio data (including the Blueprint function CreateSoundFromBytes) have been removed in favour of the excellent open-source plugin RuntimeAudioImporter.

This means the Charisma Actor component now supports playing any encoding of voice audio (and no longer crashes on UE5)! 🎉

v0.3.0: UE5 support

This release adds support for Unreal Engine 5! 🎉

Please create an issue if you run into any trouble using this plugin in Unreal Engine 5.

Aside from that, the way to select a speech encoding has been improved, making it possible to use encodings other than OGG if you bring your own support for converting bytes into a SoundWave.
