* Dūr-vāṇī (दूरवाणी): This is a common translation, combining "dūr" (far) and "vāṇī" (speech/sound). It literally means "far-sound" or "distant voice."
Other possible translations:
* Dūr-śabda-yantra (दूरशब्दयंत्र): "dūr" (far) + "śabda" (sound) + "yantra" (machine) – "far-sound machine"
* Anūka-vāṇī (अनुकावाणी): "anūka" (imitation, replica) + "vāṇī" (speech) – "imitated speech"
The best translation will depend on the context and the desired level of formality.
