Sono X10 is a Spirit box that uses a voice bank. The standard voice bank is created by small bits of the American/English alphabet, phonemes, and small cuts of speeches (NO full sentences or words) When one of the mobiles sensors are triggered, it then creates a timestamp in the voicebank, which will then be heard if a sensor is triggered again. If the mobile receives more triggers, it can then put together small bits of audio (from the soundbank) to create full words or sentences. We believe that the paranormal is able to trigger some of the sensors in a mobile phone to make contact with us. So in short, it is not the spirits voice you hear, but the spirit can create words from the voice bank by manipulating the mobiles sensors. That is the whole idea behind Sono X10. THIS APP WILL NOT WORK IN OTHER LANGUAGES - since it uses English phonemes and the English alphabet. But we are working on more languages. You can scan using the free standard sound bank or choose to buy the pro version with an extra highly effective sound bank, with more content and random signals.
