My Answering Machine Dectection将应答机检测为人。我在播放消息前播放了7秒的铃声,它只是提示用户按一个键,然后处理AMD
这是我的AMD.conf
;
; Answering Machine Detection Configuration
;
[general]
initial_silence = 2250 ; Maximum silence duration before the greeting.
; If exceeded then MACHINE.
greeting = 1500 ; Maximum length of a greeting. If exceeded then MACHINE.
after_greeting_silence = 1250 ; Silence after detecting a greeting.
; If exceeded then HUMAN
total_analysis_time = 5000 ; Maximum time allowed for the algorithm to decide
; on a HUMAN or MACHINE
min_word_length = 100 ; Minimum duration of Voice to considered as a word
between_words_silence = 50 ; Minimum duration of silence after a word to consider
; the audio what follows as a new word
;maximum_number_of_words = 3 ; Maximum number of words in the greeting.
maximum_number_of_words = 8 ; Maximum number of words in the greeting.
; If exceeded then MACHINE
silence_threshold = 256
在我的日志中,当我将其转到语音邮件时,这就是我所看到的:
-- AMD: initialSilence [2250] greeting [1500] afterGreetingSilence [1250] totalAnalysisTime [5000] minimumWordLength [100] betweenWordsSilence [50] maximumNumberOfWords [8] silenceThreshold [256]

没有铃声就可以使用,语音信箱就会被保留。
答案 0 :(得分:2)
不幸的是,答录机检测不是精确的科学,而是很多猜测。结果在很大程度上取决于应答机的问候,以及随机人员接听电话的方式。一个人通常只拿起电话后说几句话,比如“你好”或“这是约翰”,而自动系统(语音邮件或ACD)会在回答后立即说出一个问候语。因此,一个语音邮件问候语如“嗨,给我留言哔哔”有机会被检测为人类,而真正的服务员回答“早上好,谢谢你给ACME公司打电话,如何我可以直接打电话吗?“可能会被检测为机器。
您的通话流量或AMD设置没有任何问题。在您的日志中,看起来“人”决定是基于这样的事实,即只检测到4个单词,然后是超过1250秒的静音,并且基于after_greeting_silence设置触发决策算法。现在想象一下,语音邮件问候语慢慢地说:“你好,谢谢你的来电。[2s暂停]。没有人可以接你的电话......”等等。使用您的设置无法正确检测到这种特殊情况。但正如我最初所说,没有“通用”设置可以解释这个世界上的任何问候和人类回答模式。
