Multilingual testing
Multilingual chatbot testing by real speakers
Your multilingual chatbot or voice agent says it speaks your customers' languages. Real native and non-native speakers test the AI you already run, in those languages and accents, and report whether it truly understood them.

Custom Panels
Quoted
Larger or more specific panels for launches, languages and accessibility.
- Larger panels, from 15 to 50+ testers
- Specific personas you define: age groups, accents, first-time users, frustrated repeat callers
- Pre-launch panels for an AI that is not live yet
- Multilingual and accessibility panels
A multilingual chatbot can look fine in a quick check: ask a question in Spanish, get a Spanish answer. The real questions are harder. Does it understand informal phrasing, regional words and people who mix two languages in one sentence? Does it give the same policy in every language, or does a translated answer drift from the original? Does the handoff to a person work for someone who does not speak English?
Voice adds another layer. Speech recognition can struggle with accents and with non-native speakers who pause, restart or use a word from their first language. Those customers often get asked to repeat themselves until they give up.
We build panels of native speakers and non-native speakers with varied accents, matched to the languages and regions you serve. Each tester uses your AI as a real customer would and scores the session on the same fixed rubric used everywhere else, so you can compare how the AI treats customers across languages.
The result is a clear view of where each language stands. We report what testers experienced; we do not translate, retrain or configure your AI.
Signals
When it is time
If any of these sound familiar, a panel will tell you what you need to know.
You serve customers in more than one language
If your AI is offered in several languages, each one deserves the same scrutiny as your primary language.
Many customers speak English as a second language
Non-native speakers often phrase requests differently, and a bot that only understands textbook English leaves them stuck.
Your voice agent serves a wide range of accents
Accents affect speech recognition directly. Testing with the accents your callers actually have shows who gets understood.
You are adding a new language
Before a new language goes live, a panel of native speakers can confirm it reads and sounds natural and gives correct answers.
Policies must match across languages
Refund rules, prices and legal wording should be identical in every language. Testers compare answers side by side.
How the panel is set up
How it works for this use case
The panel is built around this moment, step by step.
- Step 1
Choose languages and accents
You tell us which languages, regions and accents your customers have. We match testers to them.
- Step 2
Mirror the scenarios
The same core scenarios run in every language, so differences in the results reflect the AI, not the test.
- Step 3
Test like real customers
Testers use natural phrasing, regional words, code switching and, on voice, their own accents and speech patterns.
- Step 4
Compare across languages
Scores on the fixed rubric are set side by side per language, with transcripts and translations of the key moments.
Deliverables
What you receive
Everything you need to decide what happens next.
- Rubric scores per language and per accent group
- Transcripts or recordings, with English summaries of key moments
- Any place where answers differed between languages
- Notes on speech recognition problems for voice channels
- A one-page verdict for each language tested
We only diagnose. What you do with the findings, and who does it, stays entirely your call.
Questions
Common questions
Quick answers before you request a test.
Which languages can you test?
Tell us which languages and regions your customers use and we will confirm tester availability when we scope the panel. Panels are quoted based on the languages and accents involved.
Do testers compare the answers across languages?
Yes. The same scenarios run in each language, and the report flags any place where prices, policies or next steps differed between them.
Is this a translation review?
No. Testers judge whether a real speaker of that language could get their task done, which includes whether the language sounds natural, but we do not rewrite or translate your content.
