Seeed Local Voice — Perf Test Corpus

Fixed 20-file audio corpus used to benchmark Seeed-Projects/seeed-local-voice across Jetson, Rockchip, and Raspberry Pi deployments.

The same .wav bytes are pulled by every device, so RTF / latency deltas between devices are pure compute — not input variation.

Contents

• 5× zh short (1.5 – 4.0 s)
• 5× zh long (10 – 16 s)
• 5× en short (1.5 – 4.0 s)
• 5× en long (10 – 12 s)

Audio spec: 16 kHz mono 16-bit WAV.

Each file's SHA256 + transcript is recorded in manifest.json. Fetchers should verify SHA256 on every pull.
