Voice logging captures meals by speech for speed, then converts them into structured food entries. Structured commands parse at roughly 85–90% accuracy. Vague phrasing drops to 40–60%.
01Speed comparison
| Method | Time per entry | Best for |
|---|
| Voice logging | 5–10 seconds | Hands-free, on-the-go, multi-item meals |
| Manual typing | 15–30 seconds | Precision and custom portions |
| Barcode scan | 2–5 seconds | Packaged foods with known serving sizes |
02Tips
| User type | Command example |
|---|
| Beginner | "Chicken salad, 1 cup, no dressing" |
| Fast runner | "Oats 70 grams, 1 banana, 1 scoop protein after run" |
| Parent shift worker | "Grab-and-go lunch burrito 1, half package salsa, 1 bottle water" |
03Reliability caveats
| Failure mode | When it appears | Correction method |
|---|
| Brand ambiguity | Generic phrases | Force brand names and package type |
| Unit ambiguity | Grams, cups, servings mixed | Repeat with one unit standard |
| Quiet or fast dictation | Fragmented entries | Slow speech and split sentence into smaller commands |
| Accent or device mismatch | Repeated substitutions | Adjust device language and re-try after model update |
04Correction workflow
Always treat voice-logged entries as drafts that need verification before finalizing.
| Step | Action |
|---|
| 1 | Accept parse only as draft |
| 2 | Verify totals for protein/carbs/fat and adjust servings |
| 3 | Re-log uncertain meals with manual follow-up |
| 4 | If many repeats happen, create a structured template for frequent items |

05Privacy and security
| Policy | Practical expectation |
|---|
| Audio handling | Transcribed snippets stored per app policy |
| Sensitive info | Avoid medical identifiers in spoken entries |
| Deletion | Clear drafts when changing routines |
