Speech to Text for Mac — On-Device, No Cloud, Works in Every App

VoicePrivate is a speech-to-text app for Mac that runs its recognition engine entirely on your device. No audio goes to a server. No internet connection after the initial model download. Speak, and words appear at your cursor in any app — or drop in an audio file and get a transcript back.

It runs on Apple Silicon and Intel. It works offline. There are five domain editions — Healthcare, Legal, Finance, Insurance, General — for professionals who need terminology accuracy without building a custom model from scratch. Free trial, no account required.

Built-in Mac Dictation vs. Dedicated Speech-to-Text Software

macOS has built-in Dictation. It works fine for short bursts, but it has two limitations that matter once you push it harder.

First: enhanced Dictation mode — the one that improves accuracy — routes audio to Apple servers. There is no on-device-only mode that matches the enhanced accuracy tier. For anyone handling sensitive content, that is not an acceptable tradeoff.

Second: it is a dictation tool, not a transcription tool. There is no way to drop an audio file on it, no speaker identification, no file export formats, and no domain vocabulary pre-loaded for medical, legal, or financial terminology.

A dedicated speech-to-text app closes those gaps. The right question is which one — and what actually matters for your use case.

On-Device AI — No Network Required, No Data Sent Anywhere

VoicePrivate's recognition engine runs locally on your Mac using on-device AI models. Apple Silicon Macs use the Neural Engine built into the M-series chip; Intel Macs run the same models on the CPU. Either way, audio is processed inside the machine. Nothing is transmitted.

This is not a marketing claim about encryption or data minimization — it is an architectural fact. There is no network call during transcription. No API key, no cloud account, no usage reporting to a remote server.

What that means in practice:

• Works on a plane, in a secure facility, or anywhere without Wi-Fi
• No subscription to a speech API that could change terms, go offline, or raise prices
• Audio that cannot be subpoenaed from a third-party server because it was never there

For a deeper look at why the architecture matters for compliance-sensitive work, see why on-device processing matters.

Who Uses Speech to Text on Mac — and for What

Four distinct groups reach this page with different problems.

Windows-to-Mac switchers who used Dragon or Windows Speech Recognition. Dragon for Mac still exists but costs roughly $300/year and has a narrower Mac feature set than the Windows version. Windows Speech Recognition doesn't run on macOS. VoicePrivate fills that slot: a dedicated desktop speech app with custom vocabulary, file transcription, and cross-app support, without the Dragon price tag or the subscription commitment to a cloud tool.

Professionals handling confidential content. Lawyers, accountants, therapists, and clinicians who need to dictate client notes or documentation without a cloud intermediary. The Legal, Healthcare, and Finance editions include domain vocabulary pre-loaded — medical codes, legal citation formats, financial terminology — so accuracy is high from day one without manual training.

Writers and journalists. Dictating drafts is faster than typing for many people. If you want to dictate into your writing tool of choice without a third party holding recordings of your work-in-progress, on-device is the only architecture that guarantees that.

Mac users who have outgrown built-in Dictation. File transcription, speaker identification, custom vocabulary, export formats — these are the features missing from the built-in tool. VoicePrivate adds all of them without swapping to a cloud service.

What VoicePrivate Does

• Live dictation into any app — types directly at your cursor in Slack, Notion, Word, Mail, VS Code, Pages, or any text field on macOS
• File transcription — drag and drop an audio or video file, get a transcript back, processed entirely on your Mac
• Fully offline — no internet connection after the initial model download, no Wi-Fi dependency
• Custom vocabulary — add names, acronyms, drug names, case citations, ticker symbols, or any domain term the engine needs to recognize
• Speaker diarization — identifies and labels multiple speakers in a recording (paid plans)
• AI command mode — transform transcripts with plain-language instructions: summarize, extract action items, reformat — all processed on-device
• Five domain editions: General, Healthcare, Legal, Finance, Insurance
• Export formats: .txt, .json, .md, .srt, .vtt

For the full feature overview, see the VoicePrivate features page. For the full voice dictation feature set including real-time mode details, per-app configuration, and batch processing, the voice-to-text Mac page covers each capability in depth.

Platform Requirements

VoicePrivate runs on macOS 12 Monterey and later. Apple Silicon (M1 through M4) and Intel Macs are both supported.

On Apple Silicon, the M-series Neural Engine handles model inference — that is why real-time dictation stays fast and long files don't block your machine. Intel Macs run VoicePrivate without issue, though for heavy transcription workloads Apple Silicon is the faster hardware choice. No web app, no mobile app. macOS only.

Start Free, Upgrade When Ready

VoicePrivate has a free trial that covers basic transcription and live dictation — enough to test accuracy with your own voice, microphone, and real content before committing to a plan.

Paid plans unlock:

• Speaker diarization
• Longer file transcription
• Additional export formats (.json, .md, .srt, .vtt)
• Domain-specific editions (Healthcare, Legal, Finance, Insurance)

See the pricing page for current plan details. No credit card required to start.

Frequently Asked Questions

Does Mac have built-in speech to text?

Yes. macOS includes Dictation (System Settings → Keyboard → Dictation) and Voice Control (System Settings → Accessibility). Enhanced Dictation mode improves accuracy but routes audio to Apple servers. If on-device processing matters to you, a dedicated app like VoicePrivate is the alternative.

Is VoicePrivate offline?

Yes. After the one-time model download on first launch, VoicePrivate runs entirely offline. No internet connection is needed for live dictation, file transcription, or any other feature.

Does it work on Apple Silicon?

Yes. VoicePrivate is optimized for M1 through M4. Apple Silicon uses the on-chip Neural Engine for faster processing. Intel Macs are also supported.

Can I use it in any app?

Yes. Live dictation injects text wherever your cursor is — Docs, Notion, Word, Mail, Slack, VS Code, or any text field on macOS.

What is the difference between speech to text and voice to text?

Same function, different framing. Both convert spoken audio to written text. VoicePrivate handles both real-time dictation and file-based transcription under either label. If you are coming from a Windows background and looking for a Dragon or Windows Speech Recognition equivalent on Mac, this is the same product category.
