Lock Mode: Hands-Free Dictation Without Always Listening

Push-to-talk dictation is great for quick bursts. Hold a key, say a sentence, let go. But try holding a key for ten minutes while you dictate a long email or draft a report. Your hand cramps. Your focus splits between what you’re saying and keeping the key pressed. The experience degrades fast.

That’s the tension with hands free dictation: push-to-talk gives you precise control, but some tasks need extended recording. Always-on dictation offers that freedom — but brings ambient recording, false triggers, and privacy problems along with it.

Lock mode resolves this. It’s how Tap2Talk delivers extended hands-free dictation without any of the drawbacks of always-on listening.

How Lock Mode Works

Double-tap your Tap2Talk hotkey (Right Alt or Right Ctrl). That’s it. Recording locks on.

Now you can let go of the keyboard entirely. Lean back. Pace around. Gesture with your hands. Speak at whatever length you need — thirty seconds, five minutes, ten minutes.

When you’re done, tap the hotkey once. Recording stops. Your audio is sent to Groq Whisper for transcription, the LLM cleans up grammar and punctuation, and the finished text pastes into whatever app had focus.

The critical difference from always-on dictation: you explicitly started recording (double-tap) and you explicitly stopped it (single tap). There’s no passive mic. No VAD guessing when you’re speaking. No ambient audio slipping in. The microphone was off, then you turned it on, and it stayed on until you turned it off.

The 10-Minute Timeout

Lock mode includes a safety feature. After 10 minutes of continuous recording, Tap2Talk automatically stops. This prevents a few problems:

• If you forget you’re in lock mode and walk away, you don’t end up with an hour-long recording of silence and ambient noise.
• Transcription accuracy tends to degrade on very long audio segments.
• Memory usage stays bounded.

Ten minutes is plenty for most long form voice typing tasks. If you need more time, just double-tap again to start a new lock session.

Use Cases for Lock Mode

Long Emails

Some emails need five paragraphs. Typing them takes fifteen minutes. Speaking them takes three. Double-tap to lock, narrate the entire message, tap to stop. The LLM cleanup handles grammar and punctuation, so you get a polished email ready to send.

Reports and Memos

Need to write up meeting notes, a project update, or a weekly report? Lock mode lets you speak the entire thing in one go. Talk through what happened, what was decided, and what’s next. The custom prompt feature can format the output however you need.

Essays and First Drafts

You know roughly what you want to say, but staring at a blank page isn’t productive. Double-tap, speak your ideas for five or ten minutes. Don’t worry about structure or polish — just get the thoughts out. The LLM cleanup tightens the language, and you refine from there.

Speaking a first draft is dramatically faster than writing one. Lock mode makes it practical.

Brain Dumps and Journaling

Personal reflection doesn’t have a time limit (well, 10 minutes per session). Lock mode lets you speak freely without pressure. No key to hold, no rush. Just talk through your thoughts and let the transcription capture everything.

Slack Messages That Got Too Long

You started typing a Slack message and realized it’s actually four paragraphs. Instead of pecking away at the keyboard, double-tap, say what you need to say, and paste the result. Done in 30 seconds instead of five minutes.

How Lock Mode Differs from Always-On Dictation

The hands-free experience feels similar. But the architecture is completely different.

	Lock Mode (Tap2Talk)	Always-On Dictation
Activation	Explicit double-tap	Automatic (mic always active)
Deactivation	Explicit tap (or 10-min timeout)	VAD / manual stop / timeout
Ambient recording	No (mic off until activated)	Yes (mic always hot)
False triggers	Impossible (requires deliberate double-tap)	Common
Privacy	Mic off by default	Mic always processing
Text cleanup	LLM fixes grammar and punctuation	Usually none

The most important difference is control. Always-on dictation starts when it thinks you’re talking and stops when it thinks you’ve finished. Lock mode starts when you tell it to start and stops when you tell it to stop. You’re in charge of the mic at every moment.

Lock Mode vs Hold Mode: When to Use Each

Tap2Talk gives you two recording methods. Here’s when to use each:

Hold mode (default): Hold Right Alt, speak, release. Best for:

• Quick sentences and short replies
• Chat messages
• Search queries
• Any dictation under 30 seconds

Lock mode (double-tap): Double-tap Right Alt, speak freely, tap to stop. Best for:

• Emails longer than a paragraph
• Reports and memos
• First drafts of anything
• Any dictation over 30 seconds
• Situations where you want your hands free to gesture, pace, or reference documents

You’ll naturally develop an instinct for which mode fits the moment. Short thought? Hold. Long thought? Double-tap.

Tips for Getting the Most from Lock Mode

Speak in complete thoughts. Lock mode encourages longer dictation than hold-to-talk. Lean into that. Speak in full paragraphs. The LLM cleanup works better with more context.

Don’t worry about filler words. “Um,” “uh,” “like,” “you know” — the LLM cleanup strips these automatically. Just talk naturally.

Use custom prompts. If you frequently dictate a specific type of content — emails, reports, notes — set up a custom prompt that tells the LLM how to format the output. For example: “Format as bullet points” or “Write in a professional tone.”

Add custom words. If you use technical terms, brand names, or jargon that the transcription engine might not recognize, add them to your custom words list. This improves recognition accuracy for your specific vocabulary.

Pause between ideas. Groq Whisper handles natural pauses well. You don’t need to rush. Take a breath between paragraphs — the transcription will respect those breaks.

FAQ

Is lock mode the same as always-on dictation?

No. Always-on dictation keeps the mic active at all times, processing audio continuously to detect speech. Lock mode only activates when you deliberately double-tap the hotkey, and it stops when you tap once or when the 10-minute timeout kicks in. Between sessions, the mic is completely off. Lock mode gives you hands-free convenience without ambient recording, false triggers, or passive listening.

What happens if I forget to stop lock mode?

Tap2Talk has a 10-minute timeout. After 10 minutes of continuous recording, it automatically stops. This prevents runaway recordings and keeps transcription accuracy high. If you walk away, the recording will end on its own.

Can I use lock mode with custom prompts and custom words?

Yes. Lock mode uses the same transcription and LLM cleanup pipeline as hold mode. Any custom prompt you’ve configured will be applied to the transcribed text, and any custom words you’ve added will improve recognition accuracy. The workflow is identical — the only difference is how you start and stop recording.
