Convai is the practical pick for most indies. It has a free way to start, Unity and Unreal plugins, and characters with voice, knowledge and in-scene actions. NVIDIA ACE is a set of models and SDKs (speech, small language models, Audio2Face) aimed at studios that want on-device or custom-deployed AI characters and can handle heavier integration.
