Change your voice into a strange message and set it as a ringtone on your mobile.
That is "Noise voice maker"!!
A 'noisy voice' is a synthetic voice created by special speech technology.
When you listen to this noisy voice, like a rustling sound,for the first time you will not be able to understand what it means.
After a while, however, after a moment, it will occur to you, "Ah, it's talking!".
Moreover, if you knew this in advance, almost everyone should be able to recognize that, "It's true! It's talking!".
Once you understand the meaning of the 'noisy voice', that's the only way you may be to recognise it.
After you set it as your ringtone, nobody else will be to understand your ringtone message.
For example, if you record your voice as "Call from Mr. A." or "You've got a mail from Mrs. B."
You will know who is calling or mailing you immediately but no one else will be able to recognise it. All they will hear is a rustling sound.
