It is important to note that an internet connection is required to use VoiceTra, and the speed of translation may vary depending on network connectivity. Additionally, the languages available for text input correspond to those supported by the operating system's keyboard, and proper font installation is necessary for accurate character display.
Users should be aware that certain functions or the application itself might be temporarily disabled during server maintenance. Furthermore, it is the user's responsibility to cover any communication fees incurred while using the application, as international data roaming charges can be costly.
Please be aware that this application was initially developed for research purposes and designed for individuals to test it out while traveling. The servers utilized by VoiceTra are also intended for research purposes, with recorded data being used to enhance speech translation technologies.
