The End of Pre-Recorded Audio

For decades, AAA games were limited by disk space and voice actor schedules. You couldn't record a name for every player or a reaction for every possible physics interaction. Generative Audio changes this. Morvoice provides a dedicated 'Game-Stream' protocol designed specifically for Unity and Unreal Engine 5, bypassing standard HTTP overhead to deliver audio frames directly to the audio buffer.

Architecture: Edge-Cached Inference

Latency in gaming is critical. A delay of 200ms feels like lag. Morvoice solves this with a hybrid approach. We cache common semantic clusters (greetings, combat shouts) on the edge, while streaming unique generated dialogue via UDP-based WebSockets. This ensures your NPCs react instantly.

Unity C# Implementation Example

Here is a production-ready snippet to attach a Morvoice Source to any GameObject:

using Morvoice.SDK;
using UnityEngine;

public class NPCTalker : MonoBehaviour {
    [SerializeField] private string characterVoiceId = "warrior_orc_v2";
    private MorvoiceStreamer _streamer;

    void Start() {
        _streamer = GetComponent<MorvoiceStreamer>();
        _streamer.Initialize(apiKey: SecretConfig.API_KEY);
    }

    public void OnPlayerInteraction(string playerText) {
        // 1. Send text to LLM (e.g., GPT-4)
        // 2. Stream response to Morvoice
        string responseText = LLM.GenerateResponse(playerText);
        
        // Direct buffer streaming (Low Latency)
        _streamer.Speak(responseText, characterVoiceId, Emotion.Aggressive);
    }
}
