Sesame CSM 1B

Convert text and audio input to speech generation model

Sesame CSM 1B Overview

Sesame CSM-1B is a speech generation AI model that converts text and audio inputs into realistic speech outputs. Built on the Llama architecture with a specialized audio decoder, it maintains contextual awareness during conversations by adjusting tone and expressiveness based on dialogue context. Unlike traditional speech synthesis models, Sesame CSM 1B uses a transformer-based multimodal architecture that processes text and audio simultaneously, integrating Mimi audio codec technology to deliver high-quality, natural-sounding speech while maintaining efficient compression.

Functional Advantages of Sesame CSM 1B

1. Multimodal Input Processing

Converts both text and audio inputs into realistic speech outputs through its Llama-based architecture. This integrated approach enables Sesame CSM 1B to handle diverse input formats seamlessly, making it exceptionally versatile for applications ranging from virtual assistants to accessibility tools that require natural-sounding voice responses.

2. Contextual Awareness

Sesame CSM 1B maintains conversation context, allowing it to adjust tone and expressiveness appropriately. This capability creates more human-like interactions as the model can recognize emotional nuances and conversation flow, responding with suitable intonation and emphasis that matches the dialogue’s context rather than producing flat, mechanical responses.

3. Advanced Audio Compression

Integrates semantic and acoustic information efficiently through the Mimi audio codec at 1.1kbps while preserving high fidelity. This innovative compression technology developed by Kyutai allows the model to deliver rich, detailed audio experiences without excessive computational demands, making high-quality speech synthesis more accessible across various hardware configurations.

4. Transformer-based Architecture

Unlike traditional models, it processes text and audio simultaneously using a multimodal approach for more natural interactions.

5. Versatile Voice Generation

Produces various voice types without requiring optimization for specific voices, offering flexibility in audio applications.
