    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for hotword detection on multiple devices are disclosed. In one aspect, a method includes the actions of receiving, by a first computing device, audio data that corresponds to an utterance. The actions further include determining a first value corresponding to a likelihood that the utterance includes a hotword. The actions further include receiving a second value corresponding to a likelihood that the utterance includes the hotword, the second value being determined by a second computing device. The actions further include comparing the first value and the second value. The actions further include based on comparing the first value to the second value, initiating speech recognition processing on the audio data.

    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for designating certain voice commands as hotwords. The methods, systems, and apparatus include actions of receiving a hotword followed by a voice command. Additional actions include determining that the voice command satisfies one or more predetermined criteria associated with designating the voice command as a hotword, where a voice command that is designated as a hotword is treated as a voice input regardless of whether the voice command is preceded by another hotword. Further actions include, in response to determining that the voice command satisfies one or more predetermined criteria associated with designating the voice command as a hotword, designating the voice command as a hotword.

    Abstract: Methods, systems, and computer programs are presented for unified recognition of speech and music. One method includes an operation for starting an audio recognition mode by a computing device while receiving an audio stream. Segments of the audio stream are analyzed as the audio stream is received, where the analysis includes simultaneous checking for speech and music. Further, the method includes an operation for determining a first confidence score for speech and a second confidence score for music. As the audio stream is received, additional segments are analyzed until the end of the audio stream or until the first and second confidence scores indicate that the audio stream has been identified as speech or music. Further, results are presented on a display based on the identification of the audio stream, including text entered if the audio stream was speech or song information if the audio stream was music.

    Abstract: Down scoring overcrowded bands via IDF weighting scores provides a soft way to reduce the effect of common bands from Locality Sensitive Hashing (LSH) processes. An index component indexes live video references of a live streaming infrastructure pathway process in a reference index. A scoring component scores a set of bands with a set of inverse document frequency (IDF) weighting scores in the reference index. A high score is generated for bands that are featured in a small number of references and a low score is generated for bands featured in a high number of references.

    Abstract: Systems and methods are provided herein relating to audio classification. Genres of music can be identified by detecting unique spectral features inherent to those genres. One example genre detected is techno music. Two dimensional discrete cosine transforms can be generated for consecutive windows of the spectrogram or chromagram. A max value of the energy of portions of the two dimensional discrete cosine transforms can be determined. The max value can be normalized and aggregated with max values related to neighboring windows. If the aggregate scores meet a genre threshold, the audio sample, or portions thereof, can be associated with a genre of music.
