Install SoulX-Podcast Locally ​

SoulX-Podcast is an open-source project developed by the Soul AI team, designed to transform text scripts into realistic, high-fidelity podcast-style audio. Think of it as an “AI Podcast Studio”: just input a dialogue script, and it automatically assigns voices to different speakers, adds natural intonations, laughter, sighs, and other expressive elements, generating long-form, multi-turn conversational audio that sounds remarkably human.

It excels not only in single-speaker narration (like audiobooks) but especially in creating multi-speaker, multi-turn dialogues—such as talk shows, interviews, or casual chats—making the output incredibly natural and lifelike.

Key Features & Capabilities ​

  • Multi-Speaker Dialogue Generation: Supports dynamic turn-taking between multiple characters, simulating real podcast interactions.
  • Multilingual & Dialect Support: Works with Mandarin, English, and several Chinese dialects including Sichuanese, Henanese, and Cantonese, enabling culturally rich content.
  • Zero-Shot Voice Cloning: Generate speech in a specific voice using just a few seconds of reference audio—no training required.
  • Paralinguistic Controls: Add expressive elements like laughter, sighs, pauses, and emphasis to enhance realism.
  • Long-Form Speech Synthesis: Capable of generating extended podcast episodes from long scripts.

System Requirements ​

  • Minimum 8GB RAM. 21GB+ storage recommended.
  • macOS 15+: Supports both Intel and M-series chips.
  • Windows 10/11: Intel/AMD GPUs supported, NVIDIA GPU recommended.
  • Note: If you're using an NVIDIA GPU, install NVIDIA Drivers to enable GPU acceleration.

How to use ​

Dialect Format: ​

If you want to generate speech in dialect, you can use the following options. If you don't want to use dialect, do not include dialect markers.

  • Sichuan: Sichuan dialect
  • Henan: Henan dialect
  • Yue: Cantonese, Yue dialect

Paralinguistic Controls (Tone, Emotion) ​

  • laughter: Laughing sound
  • sigh: Sighing sound

Examples ​

Below are examples of using dialects and paralinguistic controls, where [S1], [S2] represent specific speakers, <|Sichuan|> indicates the dialect used, and <|sigh|> represents a sigh:

[S1]<|Sichuan|>Oh no, this is reversed! <|laughter|>  
[S2]<|Henan|>I was just worried you might have trouble on the way! <|sigh|>
