On-device transcription turns speech into text using a recognition model running on your phone or computer. It can work without internet when the specific feature supports offline recognition and the required model or language pack is already installed. That does not mean every dictation tool works offline, that recognition is equally accurate in every mode, or that the rest of an app’s data stays on your device.
How on-device transcription works
A microphone captures speech as audio. Speech-recognition software analyzes that audio and produces text. A live feature may show partial results as you speak; a file-based feature may return a transcript in segments.
For offline recognition, the model and any required language resources must be available locally. If a feature depends on a server or lacks the right downloaded resources, it may stop working or offer reduced functionality when the connection drops. “Dictation,” “voice typing,” and “AI transcription” are labels, not guarantees that processing happens locally.
What it can do without internet
Offline capability depends on the feature, device, operating-system version, language, and setup. These documented examples cover different tasks and should not be treated as a universal list of offline features on every device.

| Feature or example | Offline capability and limits |
|---|---|
| Google Voice Access | Supports spoken commands without a network connection after the required offline speech-recognition language pack is downloaded. Google’s setup instructions cover Android versions 13 and newer. Audio may be sent to Google servers depending on configuration and system language. Google Accessibility Help. |
| Google Live Transcribe | Can use downloaded languages offline on select Android devices and on all Pixel devices running Android 12 or later. Google Pixel Phone Help. |
| Android app speech recognition | Google describes ML Kit GenAI Speech Recognition as an on-device API. Its 2026 developer guidance says basic mode is available on most Android devices with API level 31 and higher; this is developer guidance, not a promise that any consumer app offers the feature. Android Developers Blog. |
| Apple developer speech recognition | Apple’s Speech framework includes a request-level option to require on-device recognition when the recognizer supports it. Apple’s WWDC 2019 session also demonstrates recognizing speech from an audio file and accessing transcript segments. These developer examples do not establish that every Apple dictation feature or app works offline. Apple request documentation; WWDC 2019 session. |
How to check whether a feature is ready for offline use
- Identify the exact setup. Note the device, operating-system version, app, recognition feature, and language you intend to use.
- Check the feature’s documentation and settings. Look for an explicit offline or on-device option and verify that the feature supports your device and language.
- Download resources while connected. Install any required language pack or model before you lose connectivity. For Voice Access, Google’s instructions say offline speech recognition requires downloaded language packs: Get started with Voice Access spoken commands.
- Try it without a network connection. Use airplane mode and a short, non-sensitive test before relying on the feature somewhere without service. Check whether it recognizes speech and whether the specific task you need—such as commands, live captions, or dictation—still works.
- Check privacy and sync separately. A local recognition setting does not by itself tell you whether an app later syncs transcripts, backs them up, or processes other data online.
What offline transcription does not guarantee
That all audio stays on the device
Privacy claims apply to a specific feature and request, not automatically to an entire app. Apple’s requiresOnDeviceRecognition setting is intended to prevent an SFSpeechRecognitionRequest from sending audio over the network, but Apple says it is honored only when the recognizer supports on-device recognition. Google says Voice Access audio may be sent to its servers depending on configuration and system language. Separate app features may also sync or back up transcript text.
The same accuracy as server-based recognition
Apple cautions that on-device recognition requests may be less accurate. The official sources cited here do not provide a current, directly comparable cross-platform accuracy benchmark, so there is no supported universal accuracy percentage or general measure of the gap between local and cloud recognition.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Developer examples are not consumer-wide promises
Developers can build local recognition into applications using platform frameworks and APIs. Apple documents a request-level control and demonstrates audio-file recognition in its WWDC 2019 session; Google’s Android developer guidance describes an on-device speech-recognition API. Google Cloud also describes speech AI for local use in limited-connectivity settings, but that product context does not mean a typical phone’s transcription app will work offline: Google Cloud Blog.
