AI Talkback Avatar Booth
Experience Design
At the core of the activation was an intuitive, high-impact kiosk housed within a fabricated structure. Users simply walked up to the touchscreen, entered their message (or chose from preset topics), and selected a voice + avatar style. Within minutes, the system generated a multilingual talking avatar that responded on-screen with lipsync, personality, and engaging narration.
Each participant could:
Generate up to 10 versions of the avatar message in different languages
Choose from avatar styles (realistic, animated, cartoon, traditional, futuristic)
View and listen to their creation on a large 55” display with speaker support
Scan a QR code to instantly receive their AI avatar video
Features
AI-Generated Speech: Using GPT + TTS (Text-to-Speech), the booth converted simple inputs into fluent, emotionally modulated dialogue.
Avatar Personalization: Face styles, accessories, tone, and language could all be customized.
No Script Needed: The system auto-generated the message based on keywords or topic themes.
Multilingual Output: Supported Arabic, English, Hindi, Japanese, Urdu, French, Mandarin, Korean, Bahasa, and Spanish.
Instant Sharing: Visitors received their avatar video via QR code, download link, or email.

The AI Talkback Avatar Booth wasn’t just a tech activation—it was a conversation starter. It introduced visitors to the power of AI storytelling, gave them a chance to see themselves in digital form, and left them with a shareable memory. For the Saudi market, where personalization and bilingual communication are key, this solution proved both culturally adaptive and universally engaging.
With minimal manpower, compact hardware, and cloud-integrated intelligence, the booth is now ready for larger rollouts in museums, educational events, expos, and cultural festivals.
