Abstract:
Systems and methods are provided herein relating to audio matching. In addition to interest points, localized patches surrounding interest points can be used as additional discriminative information. The patches can be compressed to increase scalability while retaining discriminative information related to the localized region within the patch. Compressed patches related to interest points of an audio sample can be compared to compressed patches related to interest points of a reference sample to determine whether the two samples are a match.
Abstract:
This disclosure relates to dynamic display of content consumption by geographic location. A processor recognizes content being consumed by a set of users, and identifies geographic locations of the consumption and a set of characteristics associated with the consumption. The processor further determines at least one filter for a user of the set of users and filters the set of consumption characteristics based on the at least one filter.The processor further ranks respective consumed content based on a filtered set of consumption characteristics, and displays to the user subsets of the consumed content according to respective rankings and geographic location.
Abstract:
A computer-implemented method includes obtaining first and second binary vectors. For each of a plurality of vector locations in a first of j words in the first binary vector, the method includes shifting the binary values for the second binary vector so that a particular one of the binary values in the second binary vector is located at a vector location in a first of the k words in the second binary vector that matches the vector location in the first of j words in the first binary vector. For each of the j words in the first binary vector, the method includes aligning the second binary vector with the word in the first binary vector and determining a binary correlation score. A similarity of the first binary vector and the second binary vector can be determined based at least on one or more of the determined binary correlation scores.
Abstract:
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for verifying an identity of a user. The methods, systems, and apparatus include actions of receiving a request for a verification phrase for verifying an identity of a user. Additional actions include, in response to receiving the request for the verification phrase for verifying the identity of the user, identifying subwords to be included in the verification phrase and in response to identifying the subwords to be included in the verification phrase, obtaining a candidate phrase that includes at least some of the identified subwords as the verification phrase. Further actions include providing the verification phrase as a response to the request for the verification phrase for verifying the identity of the user.
Abstract:
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for receiving audio data encoding ambient sounds, identifying media content that matches the audio data, and a timestamp corresponding to a particular portion of the identified media content, identifying a speaker associated with the particular portion of the identified media content corresponding to the timestamp, and providing information identifying the speaker associated with the particular portion of the identified media content for output.
Abstract:
Systems and methods are provided herein relating to speed resistant audio matching. Descriptors can be generated for a received audio signal and matched with reference descriptors. A set of hits for respective reference samples can be generated based on the matching. A histogram can then be generated that correlates probe sample hit time with reference sample hit time. In one implementation, a rolling window can be used in analyzing the histogram allowing for slight variances in the timing between probe sample hits and reference sample hits. In another implementation, the histogram generated can be based on an estimated time stretch of the probe sample. In yet another implementation, a set of histograms can be generated based on a minimum speed change, a maximum speed change, and a speed step. Histograms can be evaluated to determine a most likely matching histogram.
Abstract:
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for selecting, from among a collection of videos, a set of candidate videos that (i) are identified as being associated with a particular song, and (ii) are classified as a cappella video recordings; extracting, from each of the candidate videos of the set, a monophonic melody line from an audio channel of the candidate video; selecting, from among the set of candidate videos, a subset of the candidate videos based on a similarity of the monophonic melody line of the candidate videos of the subset with each other; and providing, to a recognizer that recognizes songs from sounds produced by a human voice, (i) an identifier of the particular song, and (ii) one or more of the monophonic melody lines of the candidate videos of the subset.
Abstract:
A method includes receiving, from an audio streaming system, a probe audio sample and identifying sufficiently matching reference audio samples based on a first comparison of a first portion of the probe audio sample to reference audio samples. The method also includes, in response to determining that the sufficiently matching reference audio samples do not meet a predetermined score threshold, retaining the sufficiently matching reference audio samples, identifying additional matching reference audio samples based on a second comparison a second portion of the probe audio sample to the reference audio samples, and outputting at least one of the reference audio samples based on the first comparison and the second comparison.
