Magic Voice is an interactive voice response service launched by Idea in Tamil Nadu, India that allows users to change their voice during phone calls. It has 140 voice options available across 9 categories. While existing voice changing apps require smartphones, Magic Voice works on all mobile phones. The service is aimed at children and youth in Tamil Nadu and bridges the gap between smartphone and basic phone users. However, user interest needs to be sustained over time and expanded beyond the current youth and female user focus to increase adoption rates.
