Megaphone dictation alternative
Megaphone is the stronger general recommendation for many compatible Mac users: it is free, MIT licensed, and combines Apple SpeechAnalyzer streaming transcription with on-device cleanup, a personal Dictionary, app context, voice macros, and inline “Hey Megaphone” instructions. IraVoice is the commercial choice for people who also work on Windows or Linux, run macOS 13 to 15, or dictate into terminals and coding agents: it recognizes speech on-device with NVIDIA Parakeet and spells code names from the Git project you are working in.
Side by side
A factual comparison of the source-reviewed product boundaries. Follow the source links below for the latest competitor details.
| Factor | IraVoice | Megaphone |
|---|---|---|
| Price and license | $79 once for IraVoice Local, after the 3-day free trial; IraVoice Cloud is coming soon; a commercial app built on the MIT-licensed Handy | Free and MIT licensed, with public source code |
| Requirements | macOS 13+ on Apple silicon, Windows 10 or 11 (64-bit), and Linux (beta) | macOS 26+ on Apple silicon |
| Speech and cleanup | On-device NVIDIA Parakeet recognition with on-device filler removal; Cloud recognition and AI polish planned for IraVoice Cloud, coming soon | Streaming Apple SpeechAnalyzer transcription plus on-device Foundation Models cleanup, with deterministic Basic cleanup as fallback |
| Languages | English by default; other offline models cover 25+ languages, including Parakeet v3 and Whisper large-v3-turbo | Multiple Apple on-device speech languages; the current product site lists 30 locale choices |
| Personalization and context | Custom words, replacements and snippets, and code names read from the Git project in developer apps; only names are read, on your computer | Personal Dictionary, automatic learning, JSON import or export, recent-text context, and active app or window-title context processed locally |
| Workflow | Hold to talk or tap for hands-free dictation at the cursor; code names spelled in terminals, editors, and coding agents such as Claude Code and Codex | General cursor dictation, hold or toggle activation, voice macros, and “Hey Megaphone” generation or rewriting |
| Saved audio and video | Does not transcribe imported files | The reviewed first-party product workflow documents live dictation, not a saved-file transcription feature |
| Installation trust | Developer ID signed and notarized Mac DMG, a Windows installer, and a Linux AppImage, .deb, or .rpm (beta) | Signed DMG, but the publisher says it is not notarized and may require clearing quarantine or choosing Open Anyway; source builds are available |
| Accounts and network | No account; IraVoice Local sends no audio or text; trial and license check-ins send a salted hardware-ID hash to api.iravoice.com | No account, subscription, transcription API, API key, or Megaphone server; first-use Apple speech-model download still applies |

Questions
Yes. Megaphone’s official repository publishes the app under the MIT license and distributes a free DMG. IraVoice has a 3-day free trial, then costs $79 once for IraVoice Local. IraVoice Cloud is coming soon.
Megaphone documents on-device Apple SpeechAnalyzer transcription and on-device Foundation Models cleanup with no product server or API key. The selected Apple speech model downloads on first use, and Apple Intelligence setup can affect Smart Cleanup; deterministic Basic cleanup remains available.
This page does not claim that. Both document local speech paths. Megaphone has inspectable MIT source and no product server; IraVoice Local recognizes speech on-device and contacts its own server only for license check-ins and update checks. Verify the current build, active features, model setup, and destination app for sensitive use.
No. IraVoice is free only during its 3-day free trial and then costs $79 once for IraVoice Local. Choose it for Windows or Linux support, macOS 13 support, or code names in developer tools, not as a permanent-free substitute.
Megaphone is broader for recent text or app context, voice macros, and inline local instructions. IraVoice is narrower but reads the names in the Git project your terminal, editor, or coding agent is working in and types them as the code spells them, such as useEffect or Pipeline.swift.
Yes. Its current official site and release documentation require macOS 26 Tahoe or later on Apple silicon because the app uses Apple SpeechAnalyzer. IraVoice runs on macOS 13 or later on Apple silicon, and on Windows and Linux.
macOS 13+ on Apple silicon, Windows 10 or 11 (64-bit), and Linux (beta)
Try IraVoice for 3 days, starting with your first dictation, then keep Megaphone if its broader free feature set already fits.
