Sesame CSM-1B is an advanced speech generation AI model that transforms text and audio inputs into lifelike speech outputs. Unlike conventional TTS systems, it leverages a transformer-based multimodal architecture—combining the power of Llama’s framework with a specialized audio decoder for seamless, context-aware voice synthesis.

Key Features & Benefits

• Contextual Adaptability: Adjusts tone and expressiveness dynamically based on dialogue flow, making interactions more natural.

• Multimodal Processing: Simultaneously handles text and audio inputs for enhanced speech generation accuracy.

• High-Quality Output: Integrates Mimi audio codec technology for crisp, human-like speech with efficient compression.

Ideal for Developers & Innovators
This model is perfect for building next-gen conversational AI, virtual assistants, audiobook narration, or accessibility tools. Its efficient architecture ensures scalability, whether deployed in cloud applications or edge devices.

How It Works
Simply feed text or audio prompts, and Sesame CSM-1B generates responsive, emotionally nuanced speech. Open weights and modular design allow fine-tuning for custom use cases, from gaming NPCs to real-time translation services.

By merging cutting-edge compression with contextual intelligence, Sesame CSM-1B redefines synthetic speech—making it indistinguishable from human voices.
