Seems you don’t, and started your line with a question and continued to do so despite being provided with answers repeatedly . Is there some kink of roleplaying AI dev? You don’t really seem to have done your homework to do so.
Despite what some believe, keyword detection like “Hey Google” is only used to wake up a device from a low power state to perform more powerful listening, it’s not helpful for data tracking. Increasing the number of keywords to thousands or more (which you would need to cover the range of possible ad topics) requires more processing power and therefore defeats the purpose. Your battery would drain very noticeably if your phone was always listening for thousands of possible words.
No you are wrong. Seems your making things up on the go. More wake words to listen to more battery drain. Fact.
But sure lets play. Now that you used your “wake word counter” what use would that have ? You have ZERO context then. Completely useless .
