Accuracy you can verify
Avalon scores 97.4% on AISpeak-10, where Whisper Large v3 scores 65.1%. SpeechPulse's accuracy depends on the Whisper model you pick and your machine.
Always current, managed for you
Avalon runs on our servers and keeps improving, with no model files to manage. A pay-once app keeps the Whisper model it shipped with until its next update.
iPhone and Android and screen context
One plan covers Mac, Windows, iPhone, and Android. On a computer, Aqua reads the active window for context.
On-device and offline
SpeechPulse runs Whisper on your machine. Your audio never leaves it, and it works with no internet connection.
One-time pricing
You pay once: $99 for Windows or macOS, or $159 for both, with updates included. Over enough years, that can cost less than a subscription.
Local file transcription
SpeechPulse transcribes recorded audio files with speaker diarization and exports .srt/.vtt subtitles. Aqua Voice does not transcribe files.
Key AI and coding terms written right on AISpeak-10, Aqua’s English test.How we measuredOpenASR leaderboard
SpeechPulse runs OpenAI's Whisper on your machine, so its accuracy depends on the Whisper model you pick. We measured Avalon against Whisper Large v3 on AISpeak-10, our benchmark of AI and technical terms. This compares models, not the two apps.
SpeechPulse is an indie dictation app from AVBEAM. It runs OpenAI's Whisper on Windows or Mac and sells a one-time license. It also transcribes saved audio files, not only live speech.
Aqua Voice runs Avalon in the cloud and streams text as you speak. The trade-off is a paid service that needs an internet connection, not an offline one.
It depends on what you value. SpeechPulse is a one-time purchase that runs Whisper entirely on your own machine and can transcribe local audio files. Aqua Voice is a managed cloud service on its own model, Avalon, with published technical-term results (97.4% on AISpeak-10), real-time streaming, iPhone and Android support, and ongoing improvements. If you want an offline, pay-once desktop tool with file transcription, SpeechPulse fits; if you want managed live dictation across desktop and iPhone, Aqua Voice is the stronger choice.
They're built on opposite models. SpeechPulse is an indie app (from AVBEAM) that runs OpenAI's Whisper locally on Windows or Mac, sold as a one-time license, and it also transcribes local audio files with speaker diarization. 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 iPhone and Android support. Both let you dictate into apps, but SpeechPulse is on-device and desktop-only while Aqua Voice is cloud and cross-device.
We have not established an app-to-app accuracy advantage. SpeechPulse runs general-purpose Whisper, so its accuracy depends on which Whisper model and which machine you run. 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.
Not necessarily, and it depends on the timeframe. SpeechPulse is a one-time purchase ($99 for Windows or macOS, $159 for both) with a 30-day trial and no permanent free tier. Aqua Voice has a free Starter tier (2,000 words) and then Pro is $10/month billed annually ($120/year). Over enough years, a one-time license can cost less; what you get with Aqua Voice for the subscription is a purpose-built benchmarked model, real-time cloud processing on desktop, iPhone and Android support, and continuous improvements.
No. SpeechPulse runs Whisper on-device, so it works fully offline and your audio never leaves your machine. 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, SpeechPulse is the better fit.
No. SpeechPulse transcribes local audio files, with speaker diarization and .srt/.vtt subtitle export, which is genuinely useful for editing recordings. Aqua Voice is built for live dictation into your apps, not batch file transcription. If your main need is turning recorded audio into text or subtitles, SpeechPulse is the right tool.
Yes. Aqua Voice runs on iPhone and Android as well as Mac and Windows on one subscription. SpeechPulse is desktop-only (Windows and Mac) with no mobile app. If you want to dictate on your phone too, Aqua Voice covers that and SpeechPulse 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, where SpeechPulse runs general-purpose Whisper tuned for broad transcription.
