When you launch BlindSquare for the first time, you will see a disclaimer asking you always to rely on your orientation and traveling skills, because the accuracy of BlindSquare’s information cannot be guaranteed. If you are using BlindSquare in a language that is not supported by the speech synthesizer voices that come with iOS, the next screen will inform you that in order to be fully functional, BlindSquare needs to download and install an additional voice. If you are not connected to a Wi-Fi network, it will ask you if you would like to use your cellular phone network to perform the download. If you agree, the voice will download onto your device. If you disagree, you will be asked again when you are connected to a Wi-Fi network. When the download has started, you will see a screen informing you about the progress. Once the voice download has completed, BlindSquare will speak using the new voice.
