SpeechFast

Local voice dictation for Mac

SpeechFast is a voice dictation app for Apple Silicon Macs. It transcribes speech and cleans up fillers, repetitions, false starts, and punctuation locally, then inserts the resulting text at the active cursor in about a second with the default Parakeet engine.

The app is designed for users who need offline dictation or prefer not to send voice data to a server. It requires macOS 26, supports multiple on-device transcription engines, and does not require an account; a one-time license is available after a seven-day trial.

Key features

On-device processing

Transcription and cleanup run on the Mac, with an automated test intended to fail if either process makes a network request. The app can operate in airplane mode or on a restricted network.

Three transcription engines

Choose Parakeet, Cohere Transcribe, or Apple's built-in on-device transcription engine in Settings. Parakeet detects the spoken language automatically, while Apple's engine uses one selected language.

Multilingual dictation

Parakeet supports 25 European languages, including English, French, German, and Spanish. The language can change from one sentence to the next when using automatic detection.

Local text cleanup

SpeechFast removes fillers, repeats, and false starts and fixes punctuation before placing text at the cursor. Cleanup uses Apple Intelligence when enabled.

Keyboard-driven workflow

Hold fn to dictate, use Shift+fn for hands-free longer messages, tap fn to stop processing, or press Escape to cancel. Right Command can be used instead of fn.

Local history controls

Audio is not stored, and dictated text is kept in a local history for 30 days by default. Users can change the retention period, disable history, or erase it.

Practical use cases

  • Offline writing

    Dictate drafts, messages, and notes while travelling or working in places without reliable connectivity, since transcription and cleanup run on the Mac.

  • Sensitive work

    Keep client, health, legal, or NDA-related dictation on the device when sending voice recordings to a cloud transcription service is not appropriate.

  • Multilingual drafting

    Use Parakeet's automatic language detection to move between supported European languages during multilingual conversations or drafting.

  • Cursor-based input

    Enter text in email, documents, chats, and other applications with a text field using the keyboard shortcut instead of switching to a separate transcription window.

FAQ

What Mac does SpeechFast require?

SpeechFast requires an Apple Silicon Mac with an M1 or later chip running macOS 26. It also uses Apple Intelligence for cleanup; if Apple Intelligence is disabled, it pastes the transcript without cleanup.

How do I dictate with SpeechFast?

Hold the fn key to dictate, then release it to process and place the text at the cursor. For longer messages, use Shift+fn to keep listening hands-free and tap fn to stop. Escape cancels the dictation.

Which languages does SpeechFast support?

With Parakeet, SpeechFast supports 25 European languages, including English, French, German, and Spanish, and detects the spoken language automatically. The Apple engine uses one language selected in Settings.

Does SpeechFast store dictations?

No audio is stored. Audio remains in memory only long enough to transcribe, while text is kept in a local history for 30 days by default. The history can be shortened, disabled, or erased.

What happens after the trial?

SpeechFast includes a 7-day free trial. After the trial, dictation stops until a license is added; history and settings remain available. The license costs €39.99 once, covers three Macs, and includes updates.
