What does it even mean to record? Saving to disk? You can’t start recording after hearing a trigger word and somehow get sound from before the trigger word unless you’ve already got it... I imagine a FIFO stream or buffer that only writes to disk if a trigger word is present. Also, there may be trigger words that cause recordings even if no actions need to be taken...
