Loads a test WAV file from `testdata/speech/` +2. Runs the full FireRedVAD Python pipeline step by step, dumping intermediates: + - Raw i16 samples → `ref_samples.json` + - FBank features (pre-CMVN) → `ref_fbank.json` (shape `[T, 80]`) + - CMVN-normalized features → `ref_features.json` (shape `[T, 80]`) + - CMVN mean/variance vectors → `ref_cmvn.json` (shape `[2, 80]`) + - Per-frame speech probabilities → `ref_probs.json` (shape `[T]`) +3. Save all reference data to `testdata/firered_reference/` + +This script uses the official `fireredvad` Python package to ensure ground truth. + +#### Step B: Rust Comparison Tests + +For each preprocessing stage, load the reference JSON and compare against our Rust output: + +| Stage | Tolerance | What it catches | +|-------|-----------|-----------------| +| CMVN parsing | Exact match (f32 epsilon) | Kaldi format parsing bugs | +| FBank single frame | max abs error < 1e-4 | Window function, FFT, mel scale, log floor differences | +| FBank full file | max abs error < 1e-3 | Accumulated drift from overlap buffering | +| CMVN-normalized features | max abs error < 1e-3 | Mean/variance application order | +| Final probabilities | max abs error < 0.02 | End-to-end parity | + +#### Step C: Key Details to Match Exactly + +These are the specific numerical choices in `kaldi_native_fbank` that we must replicate: + +1. **Window function**: Povey window (Hann-like but `pow(0.85)` modified) vs standard Hann — check which one FireRedVAD uses in its config +2. **Mel scale**: HTK mel scale (`2595 * log10(1 + f/700)`) vs Slaney — must match +3. **Energy floor**: `log(max(energy, 1e-10))` or similar — the floor value matters +4. **Pre-emphasis**: Whether FireRedVAD applies pre-emphasis before FBank (check config `--dither` and `--preemphasis-coefficient`) +5. **FFT normalization**: Some implementations divide by N, others don't +6. **First/last frame padding**: How partial frames at start/end are handled +7. **CMVN application**: Global (from `cmvn.ark`) vs per-utterance — FireRedVAD uses global + +### Alternative: `kaldi-native-fbank` Rust Bindings + +If achieving numerical parity in pure Rust proves too difficult, we can fall back to **FFI bindings to `kaldi-native-fbank`** (it's a C++ library with a clean C API). This guarantees bit-exact feature extraction at the cost of a C++ build dependency. Evaluate this if Step B tolerances are not met after the pure Rust attempt. + +## Other Risks + +1. **Window buffering**: The 25ms FBank window with 10ms hop means we need to buffer 15ms of overlap between calls. This is similar to TEN-VAD's approach. **Mitigation**: Follow the established pattern from `ten_vad.rs`. + +2. **Model download size**: The streaming ONNX model is small (~2.2 MB), comparable to Silero. No concern here. + +3. **`ndarray` dimension**: FireRedVAD cache is 4-dimensional `[8,1,128,19]`. We need `Array4` from ndarray (existing backends only use up to `Array3`). This is supported by ndarray, just haven't used it yet. From 8de11b97588168f7e49bea99dfbccbffb223930d Mon Sep 17 00:00:00 2001 From: Eason WaveKat Date: Wed, 25 Mar 2026 12:19:31 +1300 Subject: [PATCH 02/15] feat: add FireRedVAD backend with pure Rust FBank + CMVN Implement FireRedVAD as a new VAD backend behind the `firered` feature flag. Includes pure Rust FBank feature extraction (matching kaldi_native_fbank), Kaldi binary CMVN parser, and streaming ONNX inference with DFSMN cache management. Validated against Python reference pipeline with max probability diff of 0.000012 across 98 frames, and against upstream fireredvad pip package on real speech audio with max diff of 0.0005 across 1150 frames.

Instrument all four backends (WebRTC, Silero, TEN-VAD, FireRedVAD) and surface the data in: - accuracy tests: per-stage µs/frame in both inline output and the markdown report - vad-lab: stage deltas piped through the pipeline → WebSocket → React UI, displayed next to RTF in each timeline header Also integrates FireRedVAD into vad-lab (backend creation, available backends list, 16 kHz resampling gate).

Today we're adding a new voice activity detection backend to wavekat-vad — FireRedVAD. It's the most accurate VAD we've tested so far, and it's now available alongside WebRTC, Silero, and TEN-VAD. + +Let me show you what it looks like and why we're excited about it. + +--- + +## QUICK RECAP [~0:20] + +If you're new here — wavekat-vad is a Rust library for voice activity detection. It gives you a simple, unified interface across multiple VAD engines. You feed in audio, you get back a speech probability. We also have vad-lab, a browser-based tool for comparing backends side by side in real time. + +--- + +## WHAT IS FIREREDVAD [~0:45] + +FireRedVAD comes from Xiaohongshu — the company behind Little Red Book. It was released in March 2026 and uses a neural network architecture called DFSMN. + +What makes it stand out? The numbers. + +On FLEURS-VAD-102, a benchmark that tests across 102 languages: + +- F1 score: 97.6 — that's the best we've seen. Silero is at 96.0, TEN-VAD at 95.2. +- False alarm rate: just 2.7% — Silero is at 9.4%, TEN-VAD at 15.5%. +- AUC-ROC: 99.6. + +It's also Apache-2.0 licensed with no usage restrictions. TEN-VAD, for comparison, has a non-compete clause. So FireRedVAD is friendlier for production use. + +The model is tiny — about 2.2 MB — and it processes audio in 10ms frames. That's finer resolution than Silero's 32ms or TEN-VAD's 16ms, which means more precise speech boundary detection. + +--- + +## DEMO: VAD-LAB COMPARISON [~1:45] + +*[Screen: vad-lab running in browser]* + +Let me show this in vad-lab. I've got all four backends running on the same audio file. You can see the waveform at the top, and below it, each backend's speech probability over time. + +*[Point to results]* + +Notice how FireRedVAD's output is smoother and more decisive — it transitions quickly between speech and silence, with fewer hesitations in the middle. WebRTC, being rule-based, gives you binary yes/no with a lot of false negatives. Silero and TEN-VAD are good, but you can see FireRedVAD catches speech segments more consistently with fewer false alarms. + +The threshold slider works the same as the other neural backends — 0.5 by default, drag it lower for more sensitivity. + +We also added per-stage timing breakdowns in this update, so you can see exactly how much time each processing step takes. + +--- + +## USING IT IN YOUR CODE [~3:00] + +Adding FireRedVAD to your project is the same as any other backend. Add the feature flag: + +```toml +wavekat-vad = { version = "0.1", features = ["firered"] } +``` + +And use it: + +```rust +use wavekat_vad::VoiceActivityDetector; +use wavekat_vad::backends::firered::FireRedVad; + +let mut vad = FireRedVad::new().unwrap(); +let probability = vad.process(&samples, 16000).unwrap(); +``` + +The ONNX model downloads automatically at build time and gets embedded in your binary. No external files needed at runtime. If you're building in CI or offline, you can point to a local model file with an environment variable. + +One thing to note: FireRedVAD only supports 16 kHz audio. If you're working with 8 kHz telephone audio, you'd need to resample. Silero handles 8k natively if that's your use case. + +--- + +## WHAT MADE THIS INTERESTING [~3:45] + +Most VAD models take raw audio samples as input. FireRedVAD is different — it expects preprocessed audio features. Specifically, 80-dimensional log Mel filterbank features with CMVN normalization. This is a Kaldi-style preprocessing pipeline. + +The upstream Python implementation uses C++ libraries for this. We reimplemented the entire pipeline in pure Rust — no C++ dependencies, no Python, everything compiles with `cargo build`. + +The tricky part was matching every numerical detail exactly. The model is trained on features from a specific pipeline, so if your preprocessing diverges even slightly, you get bad results. We built a validation suite that compares our Rust output against the Python pipeline at every stage — and the final probability difference is 0.000012. Essentially identical. + +That was the bulk of the work for this feature. Around 700 lines of Rust for the preprocessing, and a thorough validation setup to prove it works. + +--- + +## TRADEOFFS [~4:45] + +Quick summary of how FireRedVAD compares to the other backends: + +- **Accuracy**: Best overall. Highest F1, lowest false alarm rate. +- **Frame size**: 10ms — the finest resolution we have. +- **Sample rate**: 16 kHz only.
