Steam Deck & Websocket: Problem to get gender Info

[Benjo0815]

Good day,

I have tried text to speech via websocket on my steam deck (SteamOS). But I don't get any gender info of the speaking character. I have connected via postman, and only get the following data:

 "Type": "Say",
    "Speaker": "Mini-Glückskaktor-Händler",
    "NpcId": 1010445,
    "Race": "Hyuran",
    "BodyType": "Adult",
    "Payload": "Vielen Dank! Bitte beehre uns bald wieder!",
    "PayloadTemplate": "Vielen Dank! Bitte beehre uns bald wieder!",
    "Voice": {
        "Id": -1,
        "Name": "None",
        "Rate": 0,
        "Volume": 0,
        "VoiceName": null,
        "EnabledBackend": 1
    },
    "StuttersRemoved": true,
    "Source": "AddonTalk",
    "ChatType": null,
    "Language": "German"
}

At Voice -> Name should be the gender as far as I know. But it only says none.
Could this have something to do with Linux? Or maybe the German game language?
