Conversational Assistant Eva

Eva is an automated virtual assistant designed to engage in real-life conversations. It showcases the capabilities of artificial intelligence, specifically Natural Language processing (NLP). Eva was first used at the largest European technology event GITEX Europe in 2025 to answer questions related to Neurotechnology, and can be adapted for various applications, including exhibitions, company representation, and integration into the image of your startup or business.

• Speech-to-Text (STT): This component transcribes human speech into text, allowing Eva to understand spoken queries.
• Large Language Model (LLM): The transcribed text from the STT is fed into the LLM, which then processes the input and generates a response. It serves as Eva's thinking apparatus, with instructions on how to answer questions.
• Text-to-Speech (TTS): To enable Eva to "speak", the LLM's text response is converted into an audio format.
• Lip syncing: Eva's avatar's lip movements are synchronized with the audio generated by the TTS, creating a realistic visual of her speaking.
• Directional sound: To make Eva's voice appear as if it's coming directly from her avatar, we used the Focusonics Model B speaker, which can only reach the listener in a localized zone, making it an immersive experience.
