Dictation Software
for Windows PCs
Speak at your normal pace and Ambiac Dictation types it into whatever Windows app you're using — clean, punctuated, and ready to send. Made for people who write for a living.
Voice typing in any Windows app
Word, Outlook, Teams, Slack, Chrome — wherever you can put a cursor, you can talk instead of typing. No per-app setup.
Speech to text that keeps up
Ambiac Dictation listens at up to 230 words per minute and refines as you talk, so the text that lands is the text you meant.

Windows voice typing?
Windows voice typing (Win+H) is free and built in — fine for the occasional sentence. Ambiac Dictation is built for the other case: people who write all day and need dictation they can trust. Here's what changes when you switch.
- 97.4% accuracy on the AISpeak-10 benchmark — a public test of names, jargon, and technical vocabulary
- Punctuation and formatting handled automatically, with filler words cleaned up as you speak
- A custom dictionary for your own names, products, and terms
- 49 languages, with the same real-time experience in each
- The same behavior in every app you type in, from Word to your browser
The honest trade: Ambiac Dictation processes audio in the cloud, so it needs an internet connection. Its security practices are independently audited (SOC 2 Type II and ISO 27001), and Ambiac Dictation is GDPR and HIPAA compliant.
Accuracy you can check before you pay
Graytell Mythos 1.5 Speech Pro, the model inside Ambiac Dictation, scores 97.4% on AISpeak-10, a public benchmark of AI and technical vocabulary. Whisper Large v3, the open-source reference model, scores 65.1% on the same test. As of October 2025, Graytell Mythos 1.5 Speech Pro ranked #1 among proprietary models on the public OpenASR leaderboard.
AISpeak-10 is an English technical-speech dataset. Graytell Mythos 1.5 Speech Pro transcribed the key term correctly in 97.4% of clips, versus 65.1% for Whisper Large v3. That measures key-term recognition, not overall transcript accuracy or a head-to-head test of these apps. See the evaluation and methodology for a breakdown.
AISpeak-10 measures whether each clip's key term was transcribed correctly
Or skip the reading — your first 1,000 words are free, so you can test it on your own vocabulary before paying anything.

Used by people at
Ambiac Dictation has quietly saved me days of typing. First drafts go straight from my head to the page now.
Switched from Win+H for a week and never went back. The custom dictionary alone is worth it.
It gets our product names right on the first try. No other dictation tool has done that.
Emails used to pile up. Now I talk through the inbox in ten minutes and the tone still sounds like me.
The punctuation just appears exactly where I would put it. I barely edit anything anymore.
Works identically in my editor, browser, and Slack. That consistency is the part I didn't expect.
