BlueTTS drops 80MB multilingual speech model hitting 1500x real-time

Developer Maxim Melichov released BlueTTS, an ultra-lightweight open-source text-to-speech engine optimized for Hebrew and mixed-language synthesis. The ONNX-based 80MB model runs in real-time on standard CPUs and achieves up to 1500x real-time inference on GPUs.

// ANALYSIS

BlueTTS proves that high-quality voice synthesis doesn't require massive VRAM or cloud APIs, filling a crucial gap for underserved languages like Hebrew.

–Native support for mixed-language sentences (e.g., smoothly switching between Hebrew and English) solves a major localization headache
–The 80MB footprint and ONNX runtime ensure it can easily be embedded on-device, from edge hardware to standard laptops
–Releasing the full training pipeline encourages the community to replicate this efficiency for other low-resource languages
