WorkFlow
App provides user options for both receiving and broadcasting message.
For broadcasting message, go to transmit window. Type the text you want to broadcast in the text area. Click on generate button, it creates a wav-file of the text data. Now a play button appears which plays the wav-file. Now your message is being broadcasted and is saved in the chat history.
At receiving end, click on mic button in receive window to record the broadcasted message. Recorded audio undergoes some processing and returns the broadcasted text which is then saved in the chat history.
To access chat history click on history button in navigation panel.
