The quick read
- Collect ordinary requests from the intended audience with suitable permission.
- A fluent answer may silently alter a name, miss a qualifier or answer the wrong question.
Expect variation
A person may use English product names inside another language, switch scripts or write words phonetically. A system that handles separate monolingual examples may still misunderstand the combination. The task is to preserve intent across those transitions.
Build realistic examples
Collect ordinary requests from the intended audience with suitable permission. Include spelling variation, mixed terminology and audio when the product supports speech. Ask reviewers to describe the intended meaning before judging the response.
Inspect subtle errors
A fluent answer may silently alter a name, miss a qualifier or answer the wrong question. For an informational assistant, test practical requests such as opening hours and document requirements across the relevant language combinations. Keep consequential decisions under appropriate review. Record supported conditions and provide a clear fallback when comprehension is uncertain. Code-switching evaluation helps a product meet people where they communicate, while staying honest about the limits demonstrated by its tests.
