Automated Speech Recognizer (ASR)
LumenVox ASR Technical Summary
The hardware resources required by the LumenVox Automatic Speech Recognizer vary significantly depending on the exact task being performed. The main variables involve the length of audio, total number of simultaneous channels of recognition, and the type of application (specifically the size and complexity of the grammars being used).
For production telephony systems, LumenVox recommends a minimum configuration of a modern server running a 64-bit operating system with 4 CPU cores and 8GB of RAM.
