Speech-to-text for FilmCraft's Text panel ▸ Transcript (L2). User-facing behaviour, commands and model handling: docs/transcripts.md.
Transcribertrait (mono 16 kHz in, word-timedfilmcraft_project::Transcriptout) andFixedTranscriberfor tests and agents.models: Whisper model catalogue (pinned revisions, SHA-256, sizes, licences) and, with featuredownload, the verified downloader (ureq + rustls + RustCrypto). Weights are never bundled.whisper(featurewhisper): Whisper inference on candle (CPU, pure Rust).mel,vad,diarize: log-mel front end, word-bound tightening, MFCC-clustering speaker labels.
Both features are off by default and are never enabled for wasm (cargo xtask wasm checks the
crate without them).
Implemented from the published description of the model: A. Radford et al., "Robust Speech
Recognition via Large-Scale Weak Supervision" (OpenAI, 2022), the model cards and configuration
files published with the weights (config.json, generation_config.json, tokenizer.json), and
the candle tensor library's public API. Weights: OpenAI Whisper, MIT licence.
