Sopro: Real-Time TTS with Zero-Shot Voice Cloning
Read Full Article: Sopro: Real-Time TTS with Zero-Shot Voice Cloning
Sopro is a compact text-to-speech model with 169 million parameters, designed for real-time applications and capable of zero-shot voice cloning. It supports streaming and can generate 30 seconds of audio in just 7.5 seconds on a CPU, requiring only 3-12 seconds of reference audio for effective voice cloning. While it is not state-of-the-art and occasionally struggles with voice likeness, Sopro is a notable achievement given its development on a single L40S GPU and limited resources. The model is available under the Apache 2.0 license, although it currently supports only English due to data constraints.
