Abstract: The present invention relates to a telecommunications system including first and second telecommunications devices, and a computing device. The first telecommunications device is configured to receive audio input from and deliver audio output to a first user. The second telecommunications device is configured to receive audio input from and deliver audio output to a second user. The computing device is configured to deliver a set of computer-readable instructions upon request to the second telecommunications device, the instructions configured to, when executed, convert audio input received from the first user at the first device in a first human language into audio output for delivery to the second user at the second device in a second human language, the first and second languages being different.
