languageout

Languageout is a term used in computing and linguistics to denote the language that a system outputs as its result. It is commonly paired with languagein, the language from which the input is received.

In software design, languageout appears as a parameter or configuration field in APIs, translation pipelines, and text-to-speech or natural language generation systems. Setting languageout determines the target language for translation or synthesis; for example, languageout='fr' requests French output.

In multilingual workflows, languageout helps route content, apply locale rules, and select resources such as dictionaries and phonologies. It is not a universal standard, and different projects may use terms such as target language, output language, or locale rather than languageout.

Limitations and considerations: some systems separate language codes (like ISO 639-1) from regional variants (like fr-FR); languageout may need to be paired with locale settings; errors can occur if input language and output language mismatch with available models.
