Let's say you're in California talking on the phone. Would it be legal to record just your part of the conversation without having approval from the other party?
For example, could you set up a recording device on the desk and have it recording what you're saying during the whole conversation assuming it's not sensitive enough to pick up what the other person is saying also?
Since you are only recording one party, no laws restrict you from doing so.
Most states follow a "one-party law" that requires consent of at least one party in order to record a conversation between more than one party. However, California (and ten other states) has a "two-party law" that requires both parties involved to consent to being recorded.
In this case though, you aren't seeking to record a conversation but instead just your own words. There is nothing against this at all. It doesn't matter that your words are being used in conversation — they're still your own words.
