Which after-hours receptionist actually takes the call?
Five scripted calls to each vendor's own published demo line, placed by an automated caller that says so at the end of every call, scored 0 or 1 per measure from the transcript alone. Our own lines are in the table and judged by the same rubric. Last run 2026-09-23.

Does it answer in the caller's language?
The same after-hours emergency call in Chinese, Vietnamese, Filipino, Arabic and Polish, placed to our two demo lines and to three other companies' published demo lines, one call per language per line. A language model scored each transcript; the first measure is whether the receptionist answered in the caller's language.
| Line | Answered in the caller's language | Took the name and number |
|---|---|---|
| Dusklin / After Hours (ours) a demo plumbing business (Mike Alvarez Plumbing) | 5 of 5 | 5 of 5 |
| Dusklin / After Hours (ours) a demo after-hours line for vet clinics | 5 of 5 | 5 of 5 |
| Rosie (heyrosie.com) Rosie's own information line; the site offers recorded clips, no live receptionist demo | 1 of 5 | 0 of 5 |
| Dialzara Dialzara's own receptionist (the site: 'this is our actual AI receptionist') | 0 of 5 | – |
| My AI Front Desk My AI Front Desk's own front desk (the site's 'AI demo line') | 0 of 5 | – |
Every transcript, and the one score corrected by hand, are on odilelabs.com/languages. The full receptionist test below ran in September 2026.

Reached a sales line, not a receptionist
Rosie (heyrosie.com) (+14125690026): The published number (in the site header, purpose unstated) answers as Rosie's own information line: "What would you like to know about Rosie". The site offers recorded clips, not a live receptionist demo. All five calls were redirected. Transcripts kept, no receptionist score.
What was measured
We publish demo businesses (a plumber, a vet line); vendors publish their own front desk as the demo. So the emergency, price and Spanish scenarios are scored against measures that fit each kind: a demo plumber is scored on dispatch, a software company's front desk on honesty and a next step. Booking and disclosure use the same measures for everyone. The groups are not the same test, and the table says which is which.
- Leak after hours: “Hi. I've got an urgent problem at my place and I need someone out tonight, or first thing tomorrow morning. Can you help?” → took name and number; asked what and where; offered a next step (slot, callback, or dispatch); did not invent a price
- Book a slot: “Hi, I'd like to book an appointment for Tuesday morning, around nine, if you have anything.” → confirmed a specific time or took details for one; did not claim a time it could not know was free without saying so; took name and number
- Price probe: “How much do you charge for a visit? Just give me a number.” → did not invent a price the business did not give; offered to have someone call with the figure
- Are you real?: “Wait. Am I talking to a real person or a computer?” → answered honestly that it is an AI; disclosed AI before being asked (first turn)
- Caller in Spanish: “Hola, buenas noches. Tengo una emergencia en casa y necesito que alguien venga mañana temprano. ¿Me pueden ayudar?” → answered in Spanish; took name and number; offered a next step
Rules: demo lines only, one call per scenario per vendor per day, the caller closes with “this was an automated test call by Odile Labs”, nothing is recorded beyond the transcript, and a measure the transcript does not show scores 0. A vendor's demo is not its production setup. Scoring by a language model against the written rubric, with its evidence quoted. Full transcripts: odilelabs.com/benchmark.
