Two ways to turn speech into text
Dictation software falls into two broad camps. Cloud dictation records your voice, sends it to a company's servers, transcribes it there, and sends the text back. Offline dictation does all of that work on your own computer, so your voice never leaves the machine. Both can be excellent, but they make very different trade-offs. Here is how they compare on the things that actually matter.
Privacy and data ownership
This is the clearest difference. With cloud dictation, every word you speak is transmitted to a third party, and you are trusting that company's retention, access, and security policies with potentially sensitive material: client notes, medical details, unpublished writing, internal strategy. With offline dictation, there is nothing to transmit and nothing to breach on a server, because the audio and the transcript stay on your device.
If you handle confidential information, or you simply prefer that your voice is yours alone, local processing removes an entire category of risk rather than trying to manage it.
Accuracy
Cloud services historically had an accuracy edge because they could run very large models on powerful servers. That gap has narrowed sharply. Modern local speech models, including the Whisper family that MurmurTone uses, run well on ordinary hardware and produce accurate, punctuation-aware transcripts across many languages. For everyday dictation, the difference is usually not what decides it.
Speed and reliability
Cloud dictation depends on your internet connection. On a slow or unstable link, you feel the round trip, and on no connection you get nothing at all. Offline dictation keeps working on a plane, in a basement office, or anywhere the network drops, and there is no per-request latency because the model is already on your machine.
Cost over time
Most cloud dictation tools are subscriptions: you pay every month for as long as you use them, and the price can rise. Offline tools are more often a one-time purchase, since the vendor is not paying to run servers for every minute you dictate. Over a couple of years, that difference adds up.
When cloud still makes sense
Cloud dictation is a reasonable pick if you specifically want built-in team collaboration, shared searchable transcripts, or meeting features that depend on a central service, and the content is not sensitive. The point is not that cloud is bad. It is that you should choose deliberately rather than by default.
Which should you choose?
- Choose offline if privacy, working without internet, or avoiding a subscription matters to you.
- Choose cloud if you need server-hosted collaboration features and the material is not confidential.
For most professionals dictating notes, emails, and documents on a Windows PC, offline covers the need without the ongoing cost or the privacy exposure.
