This application attempts to detect answering machines at the beginning of outbound calls. It is used in a variety of ipbx application to detect answering machines. AMD settings can be configured in the Administrator Panel under Configuration > Manual Editor > Answering Machine Detection
'initialSilence' is the maximum silence duration before the greeting. If exceeded then MACHINE. 'greeting' is the maximum length of a greeting. If exceeded then MACHINE. 'afterGreetingSilence' is the silence after detecting a greeting. If exceeded then HUMAN. 'totalAnalysisTime' is the maximum time allowed for the algorithm to decide on a HUMAN or MACHINE. 'minimumWordLength'is the minimum duration of Voice to considered as a word. 'betweenWordsSilence' is the minimum duration of silence after a word to considere the audio what follows as a new word. 'maximumNumberOfWords'is the maximum number of words in the greeting. If exceeded then MACHINE. 'silenceThreshold' is the silence threshold.
Example AMD Configuration
[AMD] initial_silence = 2500 greeting = 1500 after_greeting_silence = 300 total_analysis_time = 4000 min_word_length = 120 between_words_silence = 50 maximum_number_of_words = 5 silence_threshold = 256
