Offline Voice Typing on Mac: Privacy, Limits, and Setup

Cloud speech recognition is convenient, but it is not the right choice for every environment. You may work without a reliable connection, handle private material, or simply prefer audio processing to remain on your own device.

Typeoff's local mode runs speech recognition on your Mac and can continue working without an internet connection. Here is what that means in practice.

What stays on your device

In local mode, audio transcription runs on the device. The recording is not sent to the cloud transcription service. The downloaded recognition model and its processing remain on your computer.

This is useful when you are drafting private notes, working while travelling, or using a network that is slow or unavailable.

Local transcription and AI text enhancement are separate stages. If your workflow requires every stage to remain offline, review the selected enhancement settings as well as the recognition engine. Privacy decisions should describe the complete processing path, not only the first step.

What you need before going offline

Local mode requires a one-time model download of about 894 MB. Complete the download while you have a stable connection.

To set it up:

1. Open Settings > Recognition.
2. Select Local as the recognition engine.
3. Choose Download Model.
4. Wait for the download to finish.
5. Test a short recording before disconnecting.

You can also verify the model from the same settings area if recognition behaves unexpectedly.

Languages and quality tradeoffs

Typeoff's local mode currently supports Simplified Chinese, English, Japanese, Korean, and Cantonese. Cloud mode supports a wider language set.

Local recognition may also be slightly less accurate than cloud recognition for some speakers, microphones, or environments. The advantage is that it works without sending audio away from the device and does not depend on network latency.

Choose based on the work in front of you:

• Use local mode when offline access or on-device audio processing is the priority.
• Use cloud mode when the broadest language coverage and higher recognition accuracy matter more.
• Test both with your own microphone, accent, and vocabulary before deciding on a default.

Prepare your environment

Offline recognition still depends on audio quality. A few practical changes help:

• Select the intended microphone before you disconnect.
• Keep the microphone a consistent distance from your mouth.
• Reduce fan, traffic, and room noise when possible.
• Add recurring names and specialist terms to your vocabulary.
• Make one short test recording before an important offline session.

The model cannot look up an unfamiliar product name on the internet. Clear audio and a prepared vocabulary become more important when working locally.

Automatic fallback

If the local model is already downloaded, Typeoff can fall back to local recognition when cloud mode cannot reach the network. Treat fallback as recovery, not as a replacement for preparation.

Before travelling or entering a restricted network, select local mode yourself and test it. This confirms that the model is present, the microphone is correct, and the selected language is supported.

Choose privacy based on the task

Not every sentence has the same sensitivity. A public search query and a confidential client note do not need the same processing choice.

A simple policy is:

• Default to the mode that gives you the best everyday experience.
• Switch to local mode for sensitive or disconnected work.
• Review the final text before sharing it outside your device.
• Do not dictate passwords, private keys, or authentication tokens.
