Speech generating devices, communication systems, and methods for communicating using the devices and systems are disclosed herein. In certain examples, a communication system is configured to receive a generated communication, establish a connection between a speech generating device and a computing device subsequent to receipt of the generated communication, and transmit the generated communication to the computing device. In other examples, a computing device is configured to establish a connection with a speech generating device, and receive a transmission generated by the speech generating device following the connection, the transmission including previously generated communications or real-time communication segments or proxies. In other examples, a speech generating device is configured to establish a connection with one or more computing devices, receive one or more suggestions from at least one computing device during generation of the communication, and display a suggestion on the display device as a shortcut input key.
