OpenMOSS has introduced SoulX-Podcast 1.7B, a new open-source model designed to generate natural, conversational audio. Released under an Apache 2.0 license, the 1.7 billion-parameter text-to-speech (TTS) system is engineered specifically for creating podcast-style interactions with multiple speakers.

Built upon the Qwen3 architecture, SoulX-Podcast is tailored for both English and Chinese, making it a versatile tool for bilingual applications. According to the [project's release materials](https://huggingface.co/Soul-AILab/SoulX-Podcast-1.7B), the model was trained to capture the nuances of human dialogue, aiming to produce audio that is more dynamic and engaging than standard single-speaker TTS outputs.

The release represents a growing interest in more sophisticated open-source audio generation. While many TTS models excel at reading prepared text, high-quality multi-speaker conversational models are less common. SoulX-Podcast could enable developers to build more realistic AI agents, create dynamic audio content, or prototype new forms of interactive storytelling without relying on proprietary APIs.
