Here is a good article about such data collection. You can choose not to participate (mostly), or you can join in the fun of providing them with tons of false data. I'm sure that anyone trying to monitor the phones and voices in my home are either seriously puzzled or undergoing psych evaluation and treatment. The land line phone rings probably once a week, sometimes more but usually even less - usually telemarketers and I hang up as soon as the recording clicks. The cell phone rings at wide intervals, but I don't answer it because only three people legitimately have the number and they know not to call it - so, mostly telemarketers and who knows? I'm mostly deaf, so don't play recordings, movies, etc. There are days on end when the only conversation is me asking the dog if he wants to go out, or telling him he's a good dog. Must drive them NUTS.

Digital Spies in Your Home (Not Mine)

I have no doubt that government agencies are going to use any access that citizens give them to invade their homes. This is free information as far as the government is concerned. They can collect it almost free of charge. They can store it on a permanent basis. They never know when they will use it, but if they want to use it, they will be able to.
As far as the CIA is concerned, it is going to find itself drowning in data. Computers can monitor our informational digits, but bureaucrats have to make decisions about the value of this information to their agencies. The more data they have to survey, the more paralyzed these agencies are going to become. The quality of the data will keep getting better, and the quality of the bureaucrats will keep getting lower. Competent people are not going to spend their lives digging around in the muck of digital data.
The federal government's bureaucrats have an innate desire to play God. One of the attributes of God is omniscience. Every time anyone pursues this goal, he winds up paralyzed. Yet this is basic to most federal government agencies. They feel compelled to gather more data. They don't know what to do with this information. They don't know how to analyze it. They don't know how to take action in terms of it. All they know is that they want more of it. The Internet of Things is going to give them massive quantities of data.
I think it is far more likely that companies are going to use the data to track how we use our household appliances. They are going to get huge amounts of data, and out of this data will emerge patterns of behavior. These patterns are going to be worth billions of dollars. Digital data really is the new oil. If we give our data away to these companies, they are going to put it to profitable use.
I have no need to control my appliances by voice command. I have no need to monitor them. I am not going to pay for the privilege of having government agencies and private companies invade my home and record my activities. I suggest you adopt the same attitude.
