A 16.9 MB speech model for transcription, word timestamps and speech embeddings in seven languages. See the Whistle website for model details, benchmarks and the browser demo.

Get started

pip install -U cactus-compute

import cactus

print(cactus.transcribe("clip.wav")["text"])

Use a 16 kHz WAV file. Install cactus-compute[mic] for other sample rates or microphone capture. The package downloads and caches the engine and weights on first use. This repository provides whistle.cact and checkpoints/whistle.safetensors. Runtime binaries and supported platforms live in the Cactus repository.
