20190392856 | OPERATING A VOICE RESPONSE SYSTEM BASED ON NON-HUMAN AUDIO SOURCES - Methods, systems and computer program products for operating a voice response system based on non-human audio sources are provided. Aspects include receiving, by a voice response system, an audio signal from non-human source and analyzing the audio signal to identify a source of the audio signal. Based on a determination that the source of the audio signal is controllable by the voice response system, aspects include instructing, by the voice response system, the source of the audio signal to take an action based on the audio signal. Based on a determination that the source of the audio signal is not controllable by the voice response system, aspects include providing an alert, by the voice response system that indicates the source of the audio signal. | 2019-12-26 |
20190392857 | ANSWER MACHINE DETECTION METHOD & APPARATUS - A method of recorded message detection is provided. In this an audio restream is received and a set of landmark features is identified in a section of the audio stream. From these landmark features an audio finger print for the section of the audio stream is determined. This audio finger print is compared with at least one of the plurality of stored audio finger prints, each derived from a respective audio stream. It is determined that the received audio stream is a recorded message if a derived audio finger print is substantially equivalent to one of the plurality of stored audio finger prints representing a recorded message. | 2019-12-26 |
