Use languages to control language detection.

​
Auto-detect

Omit languages or pass "auto": 
-F 'languages="auto"'
VoiceOS lets ASR detect from all supported languages.

​
Force one language

Pass a single language code: 
-F 'languages="en"'
This maps internally to the ASR language option.

​
Detect within a set

Pass a JSON array: 
-F 'languages=["en","ja","es"]'
This maps internally to enabledLanguages, allowing ASR to detect only within that set.

​
Why there is no default language

VoiceOS intentionally avoids default_language. If a caller wants one language, they should pass that language. If a caller wants detection, they should use "auto" or an array of allowed languages. This keeps the API contract simple and avoids hidden fallback behavior.
