If you wish to play the game with another audio language, you can. You simply need to download the pack for your desired language first.
To do that, make sure your platform is connected to the internet (a high-speed internet connection is recommended; each language pack is about 450MB (PC) / 660MB (console) in size) and follow the process outlined here:
On first launch of the game, you will be prompted to decide which audio language you want to play the game in. After first launch and download of an audio pack, you can switch languages by opening the Options > Audio Language menu. You will be able to choose from all the languages available in your version of the game. If you select another language than English, you'll be briefly redirected to your console's store to start the download. The game will then start to download the necessary files. You can already start playing in English with the subtitles you selected (or without, if you did not select any) while the download is happening in the background.
You can track the download progress in-game in the menu Options > Audio Language. Once all files are downloaded, the game will notify you with a popup. You can switch to the desired language any time via the Options > Audio Language menu.
To switch to the newly downloaded audio language, no game restart is required. If you would like to download another language, you can do it the same way and switch languages at any point in the game.
On PC (Ubisoft Connect):
When you press the Install button (regardless of whether you install from disc or via download) you will be asked to choose a language. By default, English will be selected. You can choose a different language or select multiple. This will trigger an additional download for the audio packs of the languages you select here before you start the game for the first time. Once the download is finished, you will be able to start the game.
The game will start in the language you selected as the main language. If you downloaded another language pack, you can change the audio language later in the Options > Audio Language menu of the game.
If you would like to download additional languages later, you can do so via the game properties in Ubisoft Connect. This will trigger an additional download before you can re-launch the game.
On PC (Steam):
If you play on Steam, you can download the language packs via the Steam client. Simply right-click on Assassin's Creed: Origins in your games library and select navigate to Properties > Language. Select your desired language from the drop-down menu and the client will download the necessary files for you.
