AI Avatar & AI Human Development Advisory
AI character development combining speech recognition, speech synthesis, image generation and LLMs
Giving AI a face and a voice. Combining LLM dialogue with speech recognition, speech synthesis and image generation produces an AI interface that feels more natural and approachable than text chat. It is used for 24-hour customer support, AI tutors in education and training, guidance in stores and facilities, and giving internal assistants a face and voice.
We cover four technology areas, speech recognition, speech synthesis, image generation and avatars, and the real-time processing that integrates them, and we develop MotionVox, our own service that generates avatar videos from text. As technical advisors we support you from technology selection to integrated real-time, low-latency design.

Frequently Asked Questions
What combination of technologies is needed to build an AI avatar?
An LLM for dialogue, speech recognition such as Whisper, speech synthesis with control over emotion and intonation, character generation with lip sync and expression control using tools such as Stable Diffusion, and real-time processing to integrate them. We map how much to invest in each element for your use case.
Can the voice resemble a specific person or speak multiple languages?
Voice cloning and multilingual output are part of the speech synthesis area we cover. We propose a configuration that fits your purpose, including how rights and consent are handled.
Can response speed reach a level suitable for real-time conversation?
Low-latency design is the key to integrating dialogue, voice and video. We design for your target response time, including real-time speech recognition, noise robustness, splitting and parallelizing processing, and multi-platform support.
What use cases is this suited to?
24-hour AI customer support, AI tutors for education and training, guidance characters in stores and facilities, entertainment characters, and giving internal AI assistants a face and a voice.
