**Large Language Models (LLMs)**

Large Language Models (LLMs) serve as the backbone of Tizzle's AI agents, enabling them to understand and generate human-like text. These models are designed to process vast amounts of information, allowing agents to engage in meaningful conversations and provide valuable insights. Tizzle employs a model from atoma which has been engineered to enhance its performance in specific domains such as digital asset management and user interactions. This allows the agents to not only comprehend complex queries but also respond with relevant and contextually appropriate information.

**Text-to-Speech (TTS)**

The Text-to-Speech (TTS) technology transforms the text generated by the LLMs into natural-sounding speech, enriching the user experience by allowing for audio interactions with the AI agents. Tizzle integrates **ElevenLabs' TTS**, known for its high-quality voice synthesis, which provides a realistic and engaging auditory experience. This capability is complemented by the **Rhubarb Lip Sync Library**, which animates the avatars of the AI agents based on the speech output, creating an engaging and lifelike interaction. The combination of TTS and visual animation helps users feel more connected to their AI companions, making conversations dynamic and interactive.
