Abstract: A system receives an audio stream from an application, and performs signal analysis on the audio stream to compute (on sound and silence) a sequence of events. The sequence of events identifies a pattern comprised of at least two of sound, silence, frequency, magnitude, duration, tone, and Dual Tone Multi Frequency (DTMF). The pattern matches a similar pattern of at least two of sound, silence, frequency, magnitude, duration, tone, and DTMF, and the signal analysis is performed on sound and silence within the audio stream. The similar pattern is associated with at least one of an automated device or human answering the call. The system determines whether the sequence of events indicates the phone call is answered by the automated device or the human, based on rules in a heuristic engine and/or a known audio print from a library of known audio prints.

Abstract: A system and method matches a digitized stream of audio signals to a known audio recording by receiving an audio stream from an application. The method performs signal analysis on sound and silence in the audio stream to compute a stream audio print of the audio stream, to identify a pattern associated with the audio stream. The method compares the stream audio print to one or more known audio prints from a library of known audio prints. The method first applies a silence constraint to match periods of silence. If application of the silence constraint is successful, the method computes a total scoring metric function to identify a match between the stream audio print and the known audio print. The total scoring metric function employs a scoring metric function that is computed at a subset of temporal points in the non-silent portion of the audio stream audio print.

Abstract: A mounting assembly for installing a radio, or equivalent apparatus, in an automobile dashboard. The dashboard mounting assembly is a box-like structure having a first open end through which a radio or equivalent device may be inserted. At least one of the peripheral walls of the assembly is formed with numerous recesses which indicate locations through which apertures are punched out to define locations at which brackets are secured.
