speechgate-rs 0.1.0

Rust speech gate with Python bindings

speechgate-rs

Rust implementation of the FASR energy speech gate with Python bindings.

import numpy as np
from speechgate_rs import EnergySpeechGate

audio = np.zeros(16000, dtype=np.float32)
gate = EnergySpeechGate(base_thresh=0.008, max_thresh=0.035)
mask = gate.compute_keep_mask(audio, sample_rate=16000)
gated = gate.apply_array(audio, sample_rate=16000)

The binding keeps the same energy-gate semantics as the Python EnergySpeechGate implementation in fasr-service-realtime: adaptive RMS thresholding, short voice-burst removal, short silence-gap filling, padding, silence pass windows, and fade envelopes.

For performance-sensitive checks, build the native extension in release mode:

env -u CONDA_PREFIX VIRTUAL_ENV=.venv maturin develop --release
uv run pytest tests -q

The test suite includes a NumPy reference implementation and verifies that the Rust binding returns identical masks/gated output/compacted output while running faster than the NumPy reference on the benchmark audio.
