数秒間立ち止まって考えると、Word Dictate が自動的にオフになります。これは修正ガイドです。問題が発生する理由 (クラウド処理、信頼性の高いインターネット要件、Microsoft 365 サインイン、Microsoft が意図的に組み込んだサイレント タイムアウト)、機能する実際のトラブルシューティング手順、思考停止時に自動停止しないオンデバイスの代替手段です。
You pause to think for a few seconds, and Word Dictate switches itself off. You start talking again, and nothing lands, because the little red mic already stopped listening. If you dictate in Microsoft Word, you have almost certainly hit this: dictation that quits the moment you stop to breathe.
This is not a bug you can patch away. Word Dictate turning off on silence is behaviour Microsoft built on purpose, and it stacks on top of a few other things that can kill a session mid-sentence. This guide explains why it happens in plain English, gives you the real fixes, and then shows you the on-device alternative that simply never auto-stops on a thinking pause.
There is not one cause. There are several, and they compound. Here is the honest chain, sourced from Microsoft's own documentation and support threads.
It stops on silence, by design. A Microsoft moderator confirmed on the official Q&A forum that "the dictation functionality is designed to interpret pauses as the end of a dictation session, and it automatically stops after a certain period of silence." The thread references a roughly 30-second silence window, and there is no native setting to switch it off. Users have complained about this for over a decade.
It is cloud-based and needs a reliable internet connection. Microsoft's own documentation states that Dictate "lets you use speech-to-text to author content in Microsoft 365 with a microphone and reliable internet connection." Your speech is processed on Microsoft's servers, not on your PC. So a dropped Wi-Fi packet, a flaky hotel connection, or a VPN hiccup ends the session in the middle of a word.
It requires a Microsoft 365 subscription and an active sign-in. Dictate is not available in perpetual Office 2016 or 2019 without a subscription. If your subscription lapses, or you get quietly signed out, dictation stops working entirely.
Your microphone can trip the silence timer early. A low input level, a muted mic, or the wrong default input device makes Word read your quiet passages as silence and fire the auto-stop sooner. Missing microphone permissions produce the "Oops, there was a problem with Dictation" error instead.
Nobody publishes these numbers next to each other, so here they are. Windows built-in Voice Typing (Win+H) shares the same cloud dependency and the same stop-on-silence behaviour, so switching to it does not solve the problem.
| Tool | Yaps | Word Dictate | Windows Voice Typing (Win+H) |
|---|---|---|---|
| Auto-stops on silence? | No cutoff | Yes (~30 sec) | Yes (~10 sec) |
| Needs internet? | No, on-device | Yes, always | Yes, always |
| Needs Microsoft 365 sign-in? | No account | Yes | No |
| Where speech is processed | Your PC | Microsoft cloud | Microsoft cloud |
| Works in Word and every other app? | Every app | Office only | Most apps |
Microsoft extended the Win+H timeout from 5 seconds to 10 seconds, which helps a little, but the cutoff is still there. There is no setting in either tool to keep dictation open indefinitely.
Work through these in order. The first four solve most "keeps turning off" and "not working" reports. The rest handle the stubborn cases.
Word Dictate is cloud-only. Check your connection and verify you are signed into an active Microsoft 365 subscription under File > Account. Reconnect Wi-Fi or switch to Ethernet if the connection is flaky.
Settings > Privacy & security > Microphone. Turn on Microphone access, Let apps access your microphone, and Let desktop apps access your microphone. On Mac, allow Word under System Settings > Privacy & Security > Microphone.
Make it the default input device, raise the input level so quiet speech is not read as silence, and run the Windows Recording Audio troubleshooter under Settings > System > Troubleshoot > Other troubleshooters.
Unplug and replug your mic, try a different USB port, or swap in another microphone to clear an "audio stream interrupted" error.
Keep a steady flow of speech or dictate in shorter bursts, and use the toggle shortcut (ALT + backtick, or the mic icon) to restart quickly. There is no native setting to disable the ~30-second auto-stop.
Turn off your VPN or firewall to confirm it is not blocking the connection to Microsoft's speech servers, then re-enable it and add an exception. Also disable conflicting Word add-ins and close apps that grab the mic (Teams, Zoom).
File > Account > Update Options > Update Now, then run an Online Repair under Settings > Apps > Microsoft 365 > Modify. Install pending Windows updates too.
Every fix above manages a limitation. None of them removes it. Word Dictate will still stop when you pause to think, still need a live internet connection, and still send your audio to Microsoft's cloud, because that is how the feature is built.
If the pause-to-think cutoff is the thing that keeps breaking your flow, the durable fix is a dictation tool that does not have a silence timeout at all. That is the wedge for Yaps. Yaps runs speech-to-text on your own PC, so there is no cloud session to time out, no internet dependency, and no Microsoft 365 sign-in.
Here is how it works in practice. You push the Yaps hotkey (hold the Fn key to record, or tap it to toggle on and off), you talk, and clean text appears in whatever field your cursor is in. Because the speech model runs on your machine, there is no round trip to a server and nothing to drop. Stop mid-sentence, stare out the window for two minutes, then finish your thought. Yaps is still listening.
The fix for "dictation keeps turning off" is not a better filler sound. It is dictation that was never designed to turn off on silence in the first place.
Yaps also cleans up the raw transcript on-device: it strips filler words and self-corrections, fixes punctuation and capitalisation, and auto-formats lists. So the "um, so, okay" filler you used to trick Word's silence timer is not a problem here, because you never needed the filler and Yaps would clean it out anyway. Dictation is multilingual too, with about 25 languages auto-detected from your speech, so you do not switch a language setting to talk in another language.
Yaps ships on Android, Windows, and macOS, plus a Chrome "Save to Yaps" extension, with iOS coming soon. The free tier covers 5,000 words a week on desktop and 1,000 a week on mobile, shared across dictation and read-aloud, which is plenty to test whether the no-cutoff difference matters to you. For the complete rundown of dictation apps with no time limit, see the full guide to dictation apps with no time limit. If you are specifically leaving Windows Speech Recognition or Voice Typing behind, the Windows Speech Recognition alternative guide covers that path, and the best dictation software for Windows roundup ranks the field.
Install Yaps for Windows or Mac for on-device dictation with no silence timeout, no internet dependency, and no Microsoft 365 sign-in. It types into Word and every other app. Also on Android, with a free tier that does not expire.
Word dictation keeps turning off mainly because it is designed to stop after a period of silence, roughly 30 seconds, which a Microsoft moderator confirmed is intentional and cannot be disabled. On top of that, Dictate is a cloud service, so an unstable internet connection, a lapsed Microsoft 365 subscription, or a low or muted microphone can each end a session mid-sentence. Fix the connection, sign-in, and mic, and it behaves. The silence cutoff, however, stays, because that part is built in on purpose.
There is no native setting to stop Word Dictate switching off during a pause, because the silence timeout is deliberate. The common workarounds are to keep a steady flow of speech, make a filler sound while you think, or dictate in shorter bursts and restart with the ALT + backtick toggle. The clean fix is to use an on-device tool without a silence timeout, such as Yaps, which keeps listening no matter how long you pause.
No. Word Dictate is a cloud service and Microsoft's own documentation requires "a microphone and reliable internet connection." Your speech is sent to Microsoft's servers for transcription, so it will not work on a plane, on unreliable Wi-Fi, or on a network that blocks outbound traffic. If you need offline dictation, use an on-device tool like Yaps, which processes speech entirely on your own PC.
Yes. Dictate requires an active Microsoft 365 subscription and sign-in, and it is not available in perpetual Office 2016 or 2019 without one. If your subscription lapses or you are signed out, dictation stops working. Tools like Yaps require no Microsoft account and no subscription for core dictation, so there is nothing to lapse.
You can dictate continuously as long as you keep talking, but Word Dictate stops after roughly 30 seconds of silence. Windows Voice Typing (Win+H) uses a shorter window, about 10 seconds, raised from the original 5. Neither has a setting to extend or disable the timeout, so any long thinking pause will end the session. On-device tools without a silence timeout, like Yaps, keep listening indefinitely.
That error usually means Word cannot access your microphone or cannot reach Microsoft's speech servers. Check that microphone permissions are on under Settings > Privacy & security > Microphone (including "Let desktop apps access your microphone"), that the right mic is set as default and not muted, and that your internet connection and any VPN or firewall are not blocking the service. Updating or running an Online Repair on Office clears the error in stubborn cases.
They are different features but share the same weakness. Win+H is the Windows built-in Voice Typing tool, and Word Dictate is the button inside Microsoft 365 apps. Both are cloud-based and both auto-pause on silence, so switching from Word Dictate to Win+H does not remove the stop-on-silence problem. Win+H's timeout is about 10 seconds versus Word's roughly 30.
Your speech audio is sent to Microsoft's cloud servers to be transcribed, because Dictate does not process speech on your device. Microsoft states the service does not store your audio or transcribed text and uses utterances only to return results, but the audio still leaves your PC to be processed. If you want your voice to never leave your machine, use an on-device tool like Yaps, where dictation is processed locally and no audio is uploaded.
Yaps is the strongest offline, no-time-limit alternative to Word Dictate, and it needs no Microsoft account or subscription for core dictation. It runs speech-to-text on your own PC with no silence cutoff, no internet dependency, and no sign-in, and it types into Word plus every other app on your system. It also cleans up the transcript on-device by removing filler words and fixing punctuation. For the full comparison, see the guide to dictation apps with no time limit.
Word Dictate turning off is not something you did wrong. It is a cloud service with a silence timeout Microsoft built in on purpose, wrapped around a live internet connection and a Microsoft 365 sign-in that each add their own ways to fail. Work through the fixes above and you will clear the mic, permission, and connection issues that account for most complaints. What you cannot fix is the pause-to-think cutoff, because there is no setting for it.
If that cutoff is the thing that keeps breaking your flow, stop fighting it. Yaps is the default recommendation here: on-device dictation with no silence timeout, no internet requirement, and no account, that types into Word and everywhere else. Word Dictate is still perfectly fine if you only dictate short bursts inside Office, always have a solid connection, and already pay for Microsoft 365. For everyone who needs to stop, think, and keep going, the tool that never turns off on silence is the one worth installing.
