Key advantage: Echo works on both iPhone and Mac, has real-time streaming (you see words as you speak), and includes a full keyboard — so you never switch apps to fix mistakes.
1. Real-time Streaming
Wispr Flow processes your speech in batches — you speak, wait, then see the result. Echo shows words appearing in real-time as you speak, with ~180ms latency. This makes a huge difference in the "feel" of voice typing.
2. Mobile (iOS)
Wispr Flow is macOS-only. Echo works as an iOS keyboard extension — you can voice-type in any app on your phone, which is where most people actually need voice input.
3. Keyboard Integration
When Echo's ASR gets a word wrong, you fix it right there with the built-in smart keyboard. No switching to another keyboard, no mouse clicking. Voice and text editing in one unified interface.
4. Price
Wispr Flow costs $15/month. Echo has a free tier with generous limits. For many users, Echo's free tier covers daily needs.
5. Bilingual Support
If you speak Chinese mixed with English, Echo handles it natively. Wispr Flow is primarily English-focused.
