They do! For example, Vision takes languageHints [1]. With the Speech API, I took an hour long tour of Rouffignac (in French) and translated it into English. I considered adding some SpeechContext [2] for things like mammoth and so on, but actually it did a fine enough job as is (besides, I had to listen to it later, as there was obviously no coverage in the cave). Disclosure: I work on Google Cloud (but not these APIs).
