Configuring AMD
Answering machine detection (AMD) is used to detect if a human voice or an answering machine is
answering the call by using a statistic algorithm. AMD is mainly applied in the predictive dialing system
in call centers, as some services need to recognize who is answering the call: a human being, an
answering machine, a fax machine, or a Modem.
AMD uses the answering rhythm (voice duration and silent time) as the statistic algorithm. Generally, if
the speaker is a human voice, there is always a period of silence after a short greeting. If the speaker is
an answering machine, there is always a short silence after a comparatively long greeting.
