New Open-Source Tool Reveals Major Speed Gaps Between macOS Speech-to-Text Engines

A new open-source benchmarking tool, Talkify Latency Bench, exposes dramatic speed differences between macOS speech-to-text engines, with Talkify leading at just 123ms and MacWhisper lagging nearly 10x slower at 1149ms across 20 measured trials.

• A new open-source benchmarking tool called Talkify Latency Bench measures the response time of macOS speech-to-text engines from recording-end to visible text output.
• Benchmark results from 20 measured trials reveal significant latency differences across engines, with Talkify leading at 123ms, followed by Spokenly at 189ms, superwhisper at 216ms, VoiceInk at 324ms, Wispr Flow at 587ms, Aqua Voice at 630ms, and MacWhisper at 1149ms.
• The engine-agnostic testing harness supports multiple trigger methods, exports results in JSON and CSV formats, and includes video comparison tools, making it extensible for testing any app that types into the frontmost field on macOS.
