Feline Synth is a unique iPhone app developed by Akihiro Maeda, offering a cat voice generator that creates sound waves based on the vibration of cat vocal cords and vocal tract resonance in real-time. This innovative tool allows users to produce a variety of cat voices, mimicking human speech and whispers.

While resembling a musical instrument with a keyboard interface, Feline Synth is not intended for music production. Users can experiment with creating music or harmonious cat voice ensembles by adjusting pitch and pronunciation with finger movements on the keyboard. The app provides guidance on voice variation through a demo feature and offers options to toggle voice tones for further customization.
