Best apps for AI voice dictation in Gmail on Android in 2026
Google’s Gmail Live rolled voice input into Gmail, Docs, and Keep on the desktop, but Android users have had voice email drafting for longer through a mix of Gboard, Assistant, and third-party dictation tools. The problem was never “can I speak an email” but “can I speak an email that reads like something I would send”.
We tested seven apps against three real workflows: dictating a full email while walking the dog, editing an existing draft by voice, and rewriting a paragraph for tone. The picks below all handle punctuation commands, work in Gmail directly, and stay accurate in noisy places.
What to look for in an Android voice-dictation app
- Native Gmail integration, not just a general keyboard trick.
- Punctuation and formatting by voice (“period”, “new paragraph”, “quote”).
- Live transcription with confidence highlighting so you can spot mistranscribed words fast.
- A tone/rewrite step, ideally with a “make this shorter” or “polish this” preset.
- Offline mode. Cell tunnels and airplane mode should not kill dictation.
- Local processing for sensitive drafts, or a clear privacy policy on cloud transcription.

The apps
1. Otter — Best for meeting-length dictation and AI summaries
Otter is built for meetings, but it doubles as an email drafting engine. Speak a message into Otter, get a cleaned-up transcript with punctuation, ask “Otter” to summarise or rewrite it into a formal email, then copy the result into Gmail. Speaker separation matters when you dictate while a colleague talks over you.
Where it falls short: The free plan caps at 300 minutes per month. Cloud transcription means confidential emails need an enterprise plan for the on-prem promise.
Pricing:
- Free: 300 min/month, 30-min per recording.
- Paid: $16.99/mo Pro annual, longer recordings, AI chat.
Platforms: Android 8.0 and up.
Bottom line: For anyone who already runs Otter in meetings and wants a longer-form dictation buffer than Gboard’s mic.
2. Gboard — Best baseline Google voice typing inside every app
Gboard has voice typing built into the keyboard. Hit the mic, speak, say “period” or “new line”, and the text lands anywhere the keyboard is active, including Gmail’s compose window. On-device recognition (Live Transcribe engine) works even in airplane mode on Pixel devices.
Where it falls short: No rewrite step. Long emails need editing; Gboard hands you a transcript, not a draft.
Pricing:
- Free: Full app.
- Paid: None.
Platforms: Android 8.0 and up.
Bottom line: Keep Gboard as the default. It is the most reliable mic in Gmail’s compose window.
3. Speechnotes — Best continuous long-form dictation
Speechnotes does not time out. Open the app, hit record, and dictate for an hour without Google’s five-minute mic cutoff getting in the way. Voice commands add punctuation, line breaks, and quotes. Copy the finished text into Gmail.
Where it falls short: No inline rewrite. Cloud recognition, so airplane mode kills it.
Pricing:
- Free: Full dictation.
- Paid: $3.99 one-time removes ads and unlocks export formats.
Platforms: Android 6.0 and up.
Bottom line: For long-form emails and letters that need one continuous dictation session.
4. Whispering — Best Whisper on-device transcription
Whispering runs OpenAI’s Whisper models locally on the phone. Speak, get a transcript that never leaves the device. Ideal for medical, legal, or sensitive HR emails.
Where it falls short: Model download is 1–2 GB. On mid-range phones, the transcription lags behind live speech by a few seconds.
Pricing:
- Free: MIT-licensed open source.
- Paid: N/A.
Platforms: Android 9.0 and up.
Download: GitHub Releases
Bottom line: The right pick when the email is private and cloud transcription is off the table.
5. SwiftKey — Best voice plus rewrite via Copilot
SwiftKey merged Copilot into the keyboard. Speak into SwiftKey’s mic, then tap the Copilot icon and ask for a shorter version, a friendlier tone, or a translation. Rewriting happens without leaving the Gmail compose window.
Where it falls short: Copilot rewrites need a live connection. Voice recognition is not as smooth as Gboard’s on Pixel hardware.
Pricing:
- Free: Full app, Copilot rewrites included.
- Paid: None.
Platforms: Android 8.0 and up.
Bottom line: The keyboard to install when you want dictation and rewriting from one input surface.
6. Microsoft Copilot — Best draft, rewrite, then paste
Microsoft Copilot stands in as a general dictation buddy. Speak a rough email into the app, ask it to produce a polished version in the tone you want, then paste into Gmail. Its context window remembers your last few drafts so follow-ups stay consistent.
Where it falls short: No direct Gmail plug-in. Copy-paste is the workflow.
Pricing:
- Free: Base voice and text chat.
- Paid: $20/mo Pro annual for GPT-based priority routing.
Platforms: Android 9.0 and up.
Bottom line: For Microsoft-first users who want Copilot to shape the draft before it hits Gmail.
7. Google Keep — Best dictate on the go, refine in Gmail later
Google Keep is the frictionless capture bucket. Tap the mic in a Keep note, dictate the email, then open the note on desktop Gmail (via Keep’s Gmail-sidebar) to refine and send. The Gemini “Help me write” button on desktop Gmail turns a rough Keep note into a polished draft.
Where it falls short: Two-step workflow. Not a direct compose route.
Pricing:
- Free: Full app.
- Paid: None.
Platforms: Android 6.0 and up.
Bottom line: For dictating rough drafts on the move that you polish at a keyboard later.
How to pick the right one
- If you already use Otter for meetings: keep it, it doubles as your email drafter.
- If you want to dictate straight into Gmail with zero fuss: Gboard.
- If you need to dictate for more than five minutes at a time: Speechnotes.
- If the email is private: Whispering runs Whisper on the device.
- If you want rewrites without leaving the compose window: SwiftKey with Copilot.
- If you use Microsoft’s tools: Copilot for drafting, paste into Gmail.
- If you dictate rough thoughts on the go and polish later: Google Keep plus desktop Gmail.
Voice dictation is finally usable enough to replace typing for a lot of emails. The trick is not the mic, it is the rewrite step: dictation gets you 80% of the way; the rewrite carries it across the line.
FAQ
Does Gmail on Android have a built-in voice dictation button?
Not a dedicated one. Gmail relies on the system keyboard’s mic, which on most phones is Gboard’s. Third-party keyboards (SwiftKey) work the same way.
Can I dictate offline?
Yes, on Pixel devices with Gboard’s on-device voice model, and always with Whispering. Cloud-based tools (Otter, Speechnotes, Copilot) need a connection.
Which app has the best punctuation accuracy?
Otter and Whispering handle punctuation from context (they insert commas without you saying “comma”). Gboard needs explicit voice commands.
Can I record a call and turn it into an email?
That is Otter’s core workflow. Import a recording, generate a summary, ask Otter to draft an email from the action items.
Does dictation drain the battery?
On-device transcription (Gboard, Whispering) uses more CPU than cloud dictation but zero cellular data. Twenty minutes of continuous use costs 3–5% on a modern phone.
