br Vocoders could in reality be usable and dont necessarily have to sound like a robot. If you're going to utilise this, you will require two in puts. 1 being a carrier wave, which's the sound youre going to vocode through and the 2 a modular voice, which would in all probability be yours. This provides a synthesizer sound thats easily known and in all sense has been utilised since the 1960s in music.
