Support & contact
SpeechSub recognizes speech and proofreads captions on your Mac. Here is how to ask for help.
What the app is for
SpeechSub recognizes speech from audio or video on your computer, with a waveform timeline, variable-speed playback, and caption proofreading. You can also import captions you already have and keep editing. Recognition uses local Whisper. Importing, proofreading, and exporting still work if a recognition model has not been downloaded.
Models, and the switch that does not work yet
Whisper comes in Base, Small, and Turbo sizes. A size downloads when you need it, from the official source first, with the file checked, and is stored in the user data directory on your computer.
The speech-or-silence file ships with the app as ggml-silero-v6.2.0.bin (885,098 bytes). It only separates speech from silence, it does not appear in model management, and you do not download it separately.
“Recognize and correct timing · Whisper + Qwen” corrects caption timing only. It does not transcribe. The model is about 1.8 GB and downloads on demand. If it is not there yet, the app asks you to download it first.
Apple Speech is a system capability. It does not appear in model management. If Settings shows that switch, it does not work yet: it is only a preview and is not connected to recognition.
What to include
Include the macOS version, SpeechSub version, the steps that failed, and any sanitized message shown by the app. Redact personal information, file paths, and caption text in screenshots. Do not send passwords, keys, complete media files, or unredacted transcripts.
Local data
Drafts, glossaries, recognition history, and downloaded models are stored in the local user data directory. You can delete drafts, clean temporary recognition files, or remove an individual history record in the app. Before uninstalling or deleting files manually, back up anything you still need.
How to contact us

Support records are kept under a 90-day retention practice after the issue is resolved, except where a legal obligation or an unresolved dispute requires longer retention.

Purchase and download
This site does not offer downloads, purchases, or store links. If the app is later distributed on the Mac App Store, Apple handles purchase and restore-purchase flows. Do not send Apple passwords, payment card details, or complete transaction records when contacting support.
