Why This Matters

Inflect-Micro-v2 represents a significant advancement in compact, high-quality local text-to-speech synthesis, enabling efficient deployment on limited hardware while maintaining naturalness and versatility. Its open-source availability encourages innovation and broader adoption in the industry, potentially transforming how consumers access personalized voice technology.

Key Takeaways

Inflect-Micro-v2

Complete local text-to-waveform speech synthesis under 10M parameters.

Fixed-voice English TTS with deterministic seeds, long-text handling, and CPU or CUDA inference.

A note from Owen I built and funded Inflect v2 independently. If this release finds a real audience, I would like to continue the project with a broader v3, which might include things like more langauges, voices, and stability improvements. If the model is useful to you, leaving a like on Hugging Face genuinely helps more people discover it.

9,356,513 deployable parameters · 37.53 MB FP32 · 24 kHz mono output

Inflect v2 uses one public API across two sizes: Micro prioritizes quality below 10M parameters; Nano prioritizes footprint below 4M.
