Before a noun, das can be either "the" or "that" (e.g. das Haus = the house; that house). (In natural speech, the stress on das would be different, but I the TTS/computer voice won't be able to make the difference since it relies only on the writing.)
Without a noun following, das can only mean "that".
("I will take the." or "The is my child." make no sense in English.)
