How we tested
We compared Otter.ai, Wispr Flow, and Voisty against the same criteria: transcription quality, latency feel, platform coverage, privacy architecture, pricing, and everyday workflow friction.

Scores are editorial 0-10 ratings, not claimed laboratory WER benchmarks.
Test protocol and sample utterances
Workflow checks
- Version basis: current public desktop releases and publisher pricing/support pages available during the verification window; exact build numbers are only named when a publisher exposes them.
- Primary desktop flow: install/open the app, configure the default hotkey, dictate into a browser text field, a notes-style editor, and a developer-style text field.
- Privacy flow: check whether transcription can run fully on-device or whether audio is uploaded for cloud processing.
- Pricing flow: verify free-tier limits, monthly/yearly/lifetime pricing, and refund language against the publisher source where available.
Repeatable sample phrases
- Write a short Slack update about shipping a faster transcription model today.
- Explain why local speech-to-text matters for NDA-covered client work.
- Add punctuation correctly: first point, privacy; second point, latency; third point, price.
- Dictate technical names: Whisper large-v3, Parakeet TDT, JSON-LD, macOS Sequoia, Windows 11.
Output checks
- Accuracy checks look for dropped words, punctuation, technical vocabulary, and product/model names.
- Latency checks are treated as workflow signals unless we have repeatable stopwatch artifacts for a product.
- Formatting checks cover whether the app inserts clean text at the cursor or requires manual copy/paste cleanup.

Wispr Flow works system-wide via a global hotkey — talk, text appears at your cursor in any app. Otter.ai is more workflow-bound — typically file-based or app-specific. From our own testing, we wouldn't reach for Otter.ai when we want to dictate a quick Slack reply.
