MacDub 0.4.3
Faster dubbing with SpeechAnalyzer
Dubbing on macOS 26+ now uses SpeechAnalyzer's fast results, which live translation already used. On the 30-minute benchmark (report):
| SpeechAnalyzer (dubbing) | 0.4.2 | 0.4.3 |
|---|---|---|
| Latency, median · p90 · max | 2.3 · 4.1 · 12.4 s | 0.7 · 2.3 · 9.3 s |
| Sentences spoken whole | 84.9 % | 87.8 % |
| Word error rate | 9.8 % | 10.3 % |
| Words lost | 1.3 % | 1.4 % |
The translated voice starts three times sooner, still in whole sentences, for half a point of word error rate. SFSpeechRecognizer (macOS 15, and the fallback) is unchanged.
The benchmark measures what the app does; --no-fast-results runs it the old way.
