Aqua Voice: I barely type long prompts now, just talk. Saved ~5 hrs typing in 2 weeks. Much more accurate than macOS dictation.
Both turn speech into clean, formatted text in any app. Aqua Voice runs its own model, Avalon, with accuracy you can verify, at $8/mo instead of $12 on annual billing. Here’s the honest comparison.
With Realtime Mode on Max, Aqua Voice refines your words as you speak: punctuation, formatting, and technical terms land in real time.
If you’re weighing an alternative to Wispr Flow, the two apps do the same core thing: press a key, talk, and get clean, formatted text in any app. Wispr Flow bets on breadth: 100+ languages and a weekly free tier. Aqua Voice bets on the model itself, one it owns and benchmarks publicly, for about a third less, with a developer API behind it.
You want accuracy you can verify against public benchmarks and an independent press test; you would rather pay $8/month than $12/month on annual billing; or you dictate code and technical terms and want a model purpose-built for them, with a developer API behind it.
You need a language outside the 49 Aqua Voice covers or a larger recurring free tier.
Both companies publish accuracy results, measured in different ways. Avalon, the model inside Aqua Voice, scores 97.4% on AISpeak-10, our public benchmark of AI and technical vocabulary, and ranked #1 among proprietary systems on the public OpenASR leaderboard at its October 2025 debut. Independent reviewers have checked it: 9to5Mac measured Aqua at 1 error to Apple Dictation’s 17.
Wispr Flow runs Canto, a speech model it built in-house, and publishes word error rates for it from its own tests on Wispr dictations and public English datasets. No test has compared the two apps directly, so try both on your own speech. You can see Avalon’s results on the OpenASR leaderboard and read more in our Avalon write-up.
AISpeak-10 is Aqua’s English technical-speech dataset. Avalon transcribed the key term correctly in 97.4% of clips, versus 65.1% for Whisper Large v3. This measures key-term recognition, not overall transcript accuracy or a head-to-head test of these apps. See the evaluation and results.
The head-to-head on model, accuracy, platforms, privacy, and price. Where a number is Wispr Flow’s own claim rather than a verified figure, it’s marked.

Avalon's results are public: #1 among proprietary systems on the independent OpenASR leaderboard at its October 2025 debut, 97.4% on AISpeak-10, and an independent 9to5Mac test. Wispr Flow's published results for its Canto model come from its own tests.
The Avalon API exposes the model inside Aqua Voice through an OpenAI-compatible endpoint at $0.39/hour of audio. Wispr Flow also offers a developer API, with WebSocket and REST endpoints.
Aqua Voice Pro is $8/month billed annually or $10 month to month. Wispr Flow Pro is $12/month billed annually or $15 month to month. On either billing, Aqua Voice costs about a third less.
If you dictate code, prompts, terminal commands, or framework names, Avalon was trained for exactly that, reaching 97.4% on our AISpeak-10 benchmark, and the desktop app reads the active window for context.
Wispr Flow advertises 100+ languages. Aqua Voice supports 49 with automatic detection. If you dictate in a language outside those 49, Wispr Flow covers it and Aqua Voice doesn't.
Wispr Flow lists 2,000 words per week on desktop and 1,000 on mobile. Aqua Voice's free Starter plan is 1,000 lifetime words, so if you plan to stay on the free plan rather than upgrade, Wispr Flow allows more.

Yes, depending on what you weigh most. Aqua Voice runs its own model, Avalon, with published benchmarks and an independent 9to5Mac press test, and costs $8/month against Wispr Flow's $12/month with annual billing. Wispr Flow advertises 100+ languages and has a larger weekly free tier. If accuracy you can verify and price matter most, Aqua Voice is the stronger pick; if you need the broadest language coverage, Wispr Flow is worth a look.
It depends on what you weigh most, and this page lays out both sides. Aqua Voice is the stronger Wispr Flow alternative if you want accuracy you can verify (97.4% on the AISpeak-10 benchmark, plus an independent 9to5Mac test), a lower price ($8/month vs $12/month with annual billing), or an OpenAI-compatible developer API. What sets it apart is a model it owns that ranked #1 among proprietary systems on the independent OpenASR leaderboard at its October 2025 debut. Wispr Flow now runs its own model too, Canto, with results from Wispr's own tests. Wispr Flow is the better pick if you need 100+ languages or the bigger weekly free tier.
Both are dictation apps that clean up speech and type into any app. Aqua Voice runs Avalon, its own model, with published benchmarks and an independent press test, on Mac, Windows, iPhone, and Android, for $8/month billed annually. Wispr Flow runs on Mac, Windows, iPhone, and Android, advertises 100+ languages with a weekly free tier of 2,000 words on desktop and 1,000 on mobile, and runs Canto, a speech model it announced in September 2026.

Wispr Flow publishes word error rates for its Canto model from its own tests on Wispr dictations and public English datasets.

Yes. Wispr Flow runs on Mac, Windows, iPhone, and Android. Aqua Voice runs on Mac, Windows, iPhone, and Android too, so the two match on every platform.
Yes. Aqua Voice Pro is $8/month billed annually ($96/year) or $10 month to month. Wispr Flow Pro is $12/month billed annually or $15 month to month. Wispr Flow does have the more generous free tier: it lists 2,000 words per week on desktop and 1,000 on mobile, versus Aqua Voice's 1,000 lifetime words on the free Starter plan.
Yes. Aqua Voice runs on Mac, Windows, iPhone, and Android.
Aqua Voice supports 49 languages with automatic detection. Wispr Flow advertises 100+ languages. If you need a language Aqua Voice does not cover, Wispr Flow has broader coverage; for English and the 49 supported languages, Aqua Voice leads on accuracy you can verify.
Both process audio in the cloud. Aqua Voice has a SOC 2 Type II audit report and is ISO 27001 certified and GDPR and HIPAA compliant, and Team plans add an org-wide Privacy Mode. Wispr Flow lists SOC 2 Type II, ISO 27001, and HIPAA on its own security pages. On security paperwork the two are close, so choose on accuracy, price, and platforms.
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.
