Not every audio method performs identically. Users can pipe sound through Siri speech synthesis, link directly to Voice Memos, load uncompressed audio from the Files directory, or embed the audio data directly inside the shortcut script.
| Method | Latency Range | Offline Reliability | Setup Complexity |
|---|---|---|---|
| Speak Text (Siri Voice) | 100, 250 ms | 100% (Local Engine) | Minimal (1 action) |
| Voice Memos Integration | 450, 900 ms | 92% (App I/O dependent) | Low (2 actions) |
| Files App Storage | 350, 700 ms | 88% (Fails if offloaded) | Moderate (File path setup) |
| Base64 Encoded Audio | 110, 180 ms | 100% (Embedded data) | Advanced (Encoding step) |
