Comparison
VoiceOS vs Aqua Voice
Both VoiceOS and Aqua Voice convert speech to text across your apps. VoiceOS goes further with Agent Mode, which lets you actually execute actions across Slack, Gmail, Calendar, Notion, Google Drive, and the web. All by voice, without leaving your current app.
What they share
Both work system-wide on Mac and Windows, turning speech into text in any app's text field. Both support multiple languages and custom vocabulary.
Where VoiceOS pulls ahead
VoiceOS has major advantages in speed, accuracy, and features. Plus, it can actually do things, not just type:
- Agent Mode: Execute real actions across Slack, Gmail, Calendar, Notion, Drive, Docs, and Sheets. Not just text output.
- Multi-step chaining: "Search the weather, email the team about it, and share the folder on Drive." One command.
- Web search: Search the internet by voice and feed results into follow-up actions.
- 300ms processing: Significantly faster than Aqua Voice's 450ms to 850ms latency.
- 98%+ English accuracy: Context awareness resolves homophones, proper nouns, and technical vocabulary that hold Aqua Voice to roughly 93% in English.
- 100+ languages: Double the language support compared to Aqua Voice's 50+.
- Automatic dictionary: VoiceOS learns terms automatically. Aqua Voice requires manual entry.
- Enterprise ready: SOC 2 Type II certified with team features and enterprise controls.
The real enemy: context switching
Dictation tools like Aqua Voice make you a faster typer. That's great. But you still have to switch apps to respond to a Slack message, send an email, or create a calendar event. VoiceOS removes that entirely. A Slack notification comes in while you're coding? Say "reply that I'll look into it after lunch" and it's sent. You never leave your editor. You never break your flow.
Accuracy and speed, measured
The two numbers that shape every dictation session: how often you have to fix the text, and how long you wait for it.

VoiceOS or Aqua Voice?

Frequently asked questions
What is the main difference between VoiceOS and Aqua Voice?
Both products can turn speech into text, but VoiceOS also connects voice to actions through Agent Mode. It can use on-screen context, search the web, draft messages, and prepare supported app actions. Important actions include a review step, so you can confirm or edit the result before anything is sent.
Which is better for dictation, VoiceOS or Aqua Voice?
For dictation alone, compare operating-system support, languages, vocabulary tools, writing-style controls, and price against your own workflow. VoiceOS works across text fields on Mac and Windows, then adds screen-aware questions and Agent Mode in the same app if you want to move beyond typing and handle follow-up work by voice.
Does VoiceOS work on both Mac and Windows?
Yes. VoiceOS has desktop apps for macOS and Windows and works in the text fields you already use across browsers, email, chat, documents, and code editors. The website detects your operating system for the primary installer, while the alternate desktop download remains available from the navigation menu.
Does VoiceOS execute voice commands automatically?
VoiceOS is designed to keep you in control of consequential actions. For tasks such as preparing a message or calendar event, it shows what it intends to do before completion so you can review or edit it. Available actions depend on the services you connect and the permissions you choose to grant.
What do I need to try VoiceOS?
You need a supported Mac or Windows computer and a microphone. Install the desktop app, grant the microphone and accessibility permissions it needs, and begin with low-risk dictation in notes or email. You can then test screen-aware questions and connect supported services when you are ready to evaluate Agent Mode.
Who should switch from Aqua Voice to VoiceOS?
VoiceOS is a strong fit when faster typing is only part of the problem. If you spend your day moving between messages, email, calendars, documents, search, and the screen in front of you, Agent Mode can help prepare the next step by voice while you remain in your current workflow.
