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.
