French AI developer Kyutai has introduced Moshi, a real-time voice AI assistant, amid delays in OpenAI's release of ChatGPT's Voice Mode. Moshi, designed to facilitate lifelike conversations, is powered by the Helium 7B model and can handle various accents and 70 different emotional speaking styles. Unlike typical AI assistants, Moshi can process two audio streams simultaneously, allowing it to listen and talk at the same time.

Kyutai developed Moshi by fine-tuning over 100,000 synthetic dialogues created using Text-to-Speech (TTS) technology. They even collaborated with a professional voice artist to enhance the quality of Moshi’s voice. This AI assistant integrates both text and audio training, optimized for multiple backends, enabling it to operate on devices like laptops without requiring cloud interaction. This design ensures privacy and security by preventing the transmission of sensitive data over the internet.

Moshi is an open-source project, with Kyutai releasing the model’s codes and framework to encourage further innovation. This approach aims to address concerns about safety and ethics, often associated with larger AI companies and their closed models. Kyutai's backers, including French billionaire Xavier Niel, support this open-source strategy.

Kyutai is also developing AI audio identification, watermarking, and signature tracking systems for Moshi, promoting accountability and traceability of AI-generated content. While Moshi is still in development, its current voice mode has impressed many, and it may prompt other AI developers to accelerate their voice-enabled projects.

A demo of Moshi is available online, and early access to the complete chatbot can be requested there. This voice-enabled AI assistant could potentially influence the integration of large language models into existing voice assistants like Alexa if it gains popularity.
