Real-time streaming, not push-to-talk
BetterDictation transcribes only after you stop speaking. Aqua Voice streams text as you speak, so you do not wait for the result.
Accuracy you can verify
Avalon scores 97.4% on AISpeak-10, where Whisper Large v3 scores 65.1%. BetterDictation's accuracy is fixed to the Whisper build it runs.
Mac, Windows, iPhone, and Android
One subscription covers them all, and the desktop app reads the active window for context. BetterDictation is Mac-only and requires Apple Silicon.
One-time $39 purchase
Pay once and own it. Over the long run, that costs less than a subscription.
On-device and offline
Whisper runs on the Apple Neural Engine, so your audio never leaves your Mac, and it works with no internet connection.
Key AI and coding terms written right on AISpeak-10, Aqua’s English test.How we measuredOpenASR leaderboard
BetterDictation runs Whisper large-v3-turbo, a general-purpose open model, on your Mac. We measured Avalon against Whisper Large v3, from the same model family, on AISpeak-10, our benchmark of AI and technical terms.
BetterDictation is an indie Mac app (betterdictation.com). It is push-to-talk: it transcribes on the Apple Neural Engine after you stop speaking. An optional $2/month Pro add-on sends text, not audio, to OpenAI for cleanup. Source: BetterDictation Pro product information, checked September 30, 2026.
Aqua Voice runs Avalon on managed servers, so the model keeps improving without updates. The trade-off is a paid cloud service that needs an internet connection.
It depends on what you value. BetterDictation is a one-time $39 Mac app that runs entirely on your device, fully offline and private. Aqua Voice is a managed cloud service on its own model, Avalon, with real-time streaming, published technical-term results (97.4% on AISpeak-10), iPhone and Android support, and ongoing improvements. If you want a cheap, offline, Mac-only tool and don't mind waiting for processing after you finish speaking, BetterDictation is great; if you want real-time dictation and a model with published results with cross-platform support, Aqua Voice is the stronger choice.
They're built on opposite philosophies. BetterDictation runs OpenAI's Whisper (large-v3-turbo) locally on the Apple Neural Engine, Mac-only, push-to-talk, and processes your audio after you stop speaking. Aqua Voice is a managed cloud app running Avalon, its own purpose-trained model, with real-time streaming and screen-context awareness on desktop, plus support for iPhone and Android. Both dictate into any app with a hotkey.
Our published results compare speech models, not the complete apps. BetterDictation runs Whisper large-v3-turbo, a strong general-purpose open model, but its accuracy is fixed to that model. Aqua Voice runs Avalon, trained specifically for technical vocabulary: it scores 97.4% on AISpeak-10 (our benchmark of AI and technical terms) where Whisper Large v3 scores 65.1%, and it ranked #1 among proprietary systems on the public OpenASR leaderboard at its October 2025 debut.
No, BetterDictation is cheaper over the long run. BetterDictation is a one-time $39 purchase (with an optional $2/month Pro add-on for OpenAI text cleanup), so you pay once and own it. Aqua Voice has a free Starter tier (2,000 words), then Pro is $10/month billed annually ($120/year). You're paying a subscription for a purpose-built, benchmarked model, real-time streaming on desktop, iPhone and Android support, and ongoing improvements, rather than a fixed local model you buy once.
No. BetterDictation runs Whisper on-device, so it works offline and your audio never leaves your Mac. Aqua Voice processes audio in the cloud to run the Avalon model, so it needs an internet connection. If fully offline, on-device dictation is a requirement, BetterDictation is the better fit.
Yes, and this is a real difference. BetterDictation is push-to-talk: it captures your speech and only transcribes after you stop, so you wait for the result. Aqua Voice streams text live as you speak, so words appear immediately. If you want to see your dictation land in real time, Aqua Voice has the edge.
Yes. BetterDictation is Mac-only and requires Apple Silicon. Aqua Voice runs on Mac, Windows, iPhone, and Android on one subscription, so if you work across a PC or want dictation on your phone, Aqua Voice covers ground BetterDictation does not.
Yes, it's what Aqua Voice is built for. Avalon was trained on the speech developers and AI users produce, reaching 97.4% accuracy on technical terms like programming keywords, framework names, and CLI commands. It also reads the active app for context and offers the Avalon API for developers.
