Repeat five times: “The voice is not stored.” Then say, “The voice is turned into text.” All the laws concern the storing of voice as in a tape recording. These laws have been left in the past with the advances in technology. We have gone from old analog storage of conversation to digital and from digital to text. Then you can do a word search like you do in a document of text. However, searches are now done with high tech software.
Then, there is the matter of high tech bugs. Technology has come a long way with micro circuitry. Bugs can be wireless micro cameras powered by lithium batteries with micro wireless microphones. Your own smart phone can become a bug. Soon bugs will fly into a room and land on top of a picture frame.
If someone is recording your voice phone calls, whether they are storing them as text or not, they are breaking the law if you were not made aware of the recording and they did not get a subpoena. This includes the phone company. I’d love to see this end up in the SCOTUS.
