How to dictate faster and more accurately
A few simple habits make voice typing dramatically better: use a decent microphone in a quiet space, speak in steady phrases rather than word by word, and let the app handle punctuation and cleanup so you're not editing afterward. Here's the practical guide.

Most people who try dictation and give up blame the software, when the real culprit is usually the microphone, the room, or how they're speaking. Get those right and on-device dictation is fast and accurate enough to replace most typing.
The fundamentals
- Microphone matters most. A built-in MacBook mic is fine in a quiet room; a headset or external mic is much better with any background noise. This single change fixes most accuracy complaints.
- Reduce background noise. Quiet rooms transcribe far better than cafes or open offices.
- Speak in phrases, at a steady pace. Natural sentences beat slow, robotic word-by-word dictation. The model uses context to get words right.
- Don't over-enunciate. Speak normally. Exaggerated pronunciation often hurts more than it helps.
Getting clean text, not a raw transcript
- Let the app punctuate. Good tools add punctuation automatically. Fighting it manually means more typing, which defeats the point.
- Use a cleanup or rewrite mode to remove filler ("um", "you know") and tidy rambling into clean sentences. In Relay, that's the Clean and Rewrite modes.
- Dictate the draft, edit briefly after. Speak the whole thought, then do one quick cleanup pass rather than correcting mid-flow.
For technical and specialized work
- Add custom vocabulary for names, jargon, and product terms so they stop coming out wrong (in Relay, custom vocabulary arrives in 0.3).
- For AI prompts and code, dictate the instruction naturally and let a rewrite mode tighten it. See best voice for coding and AI prompts.
Relay applies most of this for you: on-device transcription, automatic punctuation, and Clean/Rewrite modes so a slightly imperfect raw transcript still comes out polished. Free during beta. For what affects accuracy under the hood, see how accurate on-device transcription is.

Frequently asked questions
How can I make voice dictation more accurate?
The biggest wins are a decent microphone and a quiet room, then speaking in natural, steady phrases rather than word by word. Adding custom vocabulary for names and jargon helps too. Cleanup modes fix punctuation and filler so the final text reads well.
Why is my dictation full of mistakes?
Usually the microphone or environment, not the app. A distant or low-quality mic, background noise, speaking too fast, or heavy specialized terms all reduce accuracy. A headset mic in a quiet room makes the biggest difference.
Is it faster to dictate than to type?
For most people, yes. A 2016 Stanford and Baidu study (Ruan et al., arXiv:1608.07323) measured speech input at 153 words per minute against 52 typed, about 2.9 times faster. With automatic punctuation and a cleanup pass, dictating a draft and lightly editing is faster than typing it from scratch.
Do I have to speak punctuation out loud?
With good tools, no. They add punctuation automatically from the rhythm of your speech. You can still say punctuation explicitly when you want precise control, but you shouldn't have to for normal writing.
