*** IMPORTANT NOTE *** - Each voice can be purchased through a simple In-App purchase process. App includes a 7 days trial to test voices. - Recent Google apps updates force using their own voices. GPS apps (maps) or the AI assistant, ignore text-to-speech settings, only allowing Google TTS. This decision from Google has been strongly discouraged by the Android community but as for now, we cannot ensure compatibility for this apps. As an alternative, you can use Vocalizer voices on other GPS apps like "Navigator" or "Sygic", that are compatible with Google Speech APIs. ***************************
