I don't know the circumstances of your redundancy, but can I just say pipflower, be careful and don't do anything rash. I imagine you're feeling a bit angry and upset about the prospect of losing your job, and perhaps feel you are spiting them in some way by asking them to remove your voice. Remember though they can easily record someone elses voice. What you have to consider is when or if you later ask them for a reference for a new job, perhaps they will not be so favourable with recommending you. Whereas if you leave on good terms and have a good work record, then references will be forthcoming. Anyway what a nice accolade for you, it means your company thought you had a welcoming and personable voice to represent them. That is something you can put in your personal statement on your cv. Good luck in the future.
