How to Dictate Into Spark on a Mac
Spark is a fast, clean email client, but writing long replies by hand still slows you down. The good news: because Spark uses a normal macOS text field, you can talk your emails out loud and let voice-to-text do the typing. Here is exactly how to dictate into Spark on your Mac.
Key takeaways
- Spark relies on the Mac's dictation, so any system-wide voice tool works inside it.
- Click into the email body first so your cursor is active, then start dictating.
- On-device AI cleanup turns rambling speech into a punctuated, ready-to-send draft.
- With BlaBlaType, your audio and email text stay 100% on your Mac, even offline.
Does Spark have its own dictation?
No. Spark, made by Readdle, focuses on inbox features like smart folders and send-later. It does not include a built-in speech-to-text engine. Instead it inherits whatever dictation you have set up at the macOS level. That is actually good news, because it means you are free to choose the voice tool that fits you, rather than being stuck with one baked-in option.
There are two realistic routes. The first is Apple's own dictation, which Apple documents in its Mac dictation guide. The second is a dedicated system-wide app like BlaBlaType that types into any field, adds AI cleanup, and keeps every word on-device. If email is a big part of your day, it is worth reading our wider guide on how to dictate emails on a Mac before you commit to one.
Set up dictation for Spark in four steps
This walkthrough uses BlaBlaType because it works the same way in Spark as in any other app, and it does not send your audio anywhere. The flow is nearly identical for any system-wide dictation tool.
Install a system-wide dictation app
Download BlaBlaType from /download/mac and grant the accessibility and microphone permissions macOS asks for. These let the app type into apps like Spark and hear your voice.
Pick your shortcut and model
Choose a push-to-talk or toggle shortcut, then pick a local model. The on-device Whisper and Parakeet models transcribe entirely on your Mac, so no audio is uploaded.
Open a message in Spark and click the body
Start a new email or a reply, then click into the message body so the cursor is blinking. Whatever you dictate lands exactly where that cursor sits.
Press your shortcut and speak
Hold or tap your shortcut and talk naturally. When you stop, the cleaned-up text appears in Spark, with filler words removed and punctuation added. Review, then send.
That is the whole loop. Most people speak around three to four times faster than they type, so a reply that would take a few minutes to peck out becomes a quick spoken paragraph. To see whether the time saving is real for you, we broke down the numbers in dictation vs typing in 2026.
How the words get from your voice into Spark
It helps to picture the pipeline. Your speech is captured by the microphone, transcribed by a local model, polished by on-device AI, and then typed into the Spark message field. Every stage happens on your Mac.
The AI cleanup stage is what separates modern dictation from the robotic voice typing of a decade ago. Raw speech is full of "um", restarts and missing commas. On-device AI rewrites that into a clean draft, fixes grammar, and can even adapt the tone so a quick spoken note reads like a proper email. If a term like Whisper is new to you, the general background on speech recognition is a useful primer.
Which dictation method should you use in Spark?
Both Apple Dictation and a dedicated app will put words on the screen, but they differ on the things email writers care about: cleanup quality, privacy and where the audio goes.
| Feature | Apple Dictation | BlaBlaType |
|---|---|---|
| Works inside Spark | Yes | Yes |
| AI cleanup and punctuation | Limited | Yes |
| Fully on-device | Mixed | Yes |
| Custom dictionary for names | No | Yes |
| Works offline | Mixed | Yes |
| Price | Free | No-card trial, then paid |
Apple Dictation is free and fine for a quick sentence. Where it falls short is longer, messier email where you want punctuation, filler removal and correct spelling of names and jargon done for you. That is the gap BlaBlaType fills, and it does so while keeping your voice and text on the Mac.

A few habits make dictated Spark emails read even better. Speak in full thoughts rather than word by word, because the AI cleanup uses context to punctuate. Add the recipient's name and any product terms to your custom dictionary so they are always spelled right. And do a quick read before you send, the same as you would with typed email. Dictation is faster, not a licence to skip proofreading.
If you write in more than one language, note that BlaBlaType supports 90+ languages with optional translate-as-you-speak, so you can talk in one language and have the email arrive in another. That is handy for replying to international clients without switching keyboards.
Frequently asked questions
Does Spark have built-in dictation on Mac?
Spark does not ship its own voice-to-text engine. Because Spark uses a standard macOS text field, you dictate into it with either Apple Dictation or a system-wide dictation app like BlaBlaType, which types wherever your cursor is.
How do I dictate an email in Spark by voice?
Open a new email in Spark, click into the body so the cursor is blinking, then start your dictation shortcut. Speak the email naturally and the transcribed, cleaned-up text appears in the message. Review, then send.
Is dictating into Spark private?
It depends on the tool. Apple Dictation and cloud dictation apps may process audio on Apple or third-party servers. BlaBlaType runs speech recognition 100% on-device, so your voice and the email text never leave your Mac.
Can I fix punctuation and filler words automatically?
Yes. BlaBlaType applies on-device AI cleanup that removes filler words, fixes punctuation and grammar, and can adapt tone, so a rambling spoken email arrives as a clean draft in Spark without manual editing.
Does voice-to-text work in Spark offline?
With an on-device app like BlaBlaType, yes. The local Whisper and Parakeet models transcribe without an internet connection, so you can dictate into Spark on a plane or anywhere with no signal.
