Is it possible to make RecognizerIntent, or any other way to use speech recognition in android, to detect the language that you're talking, and send the result in that language. Like, if I say a romanian word, to detect that it is romanian, then send me that word? Are there any other options for speech recognition rather than RecognizerIntent? I have an app that actually combines words, like, if I say a word in french then one in english, it will actually combine them, like "I like filles".
The android.speech APIs (RecognizerIntent, RecognitionListener, ...) do not offer anything towards multi-language speech recognition nor language detection. You would need to find a service that offers these and interact with it directly, by-passing the standard Android APIs.
UPDATE: Starting with API level 34, there is onLanguageDetection and related EXTRAs.
