| 20110257974 | GEOTAGGED ENVIRONMENTAL AUDIO FOR ENHANCED SPEECH RECOGNITION ACCURACY - Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for enhancing speech recognition accuracy. In one aspect, a method includes receiving geotagged audio signals that correspond to environmental audio recorded by multiple mobile devices in multiple geographic locations, receiving an audio signal that corresponds to an utterance recorded by a particular mobile device, determining a particular geographic location associated with the particular mobile device, generating a noise model for the particular geographic location using a subset of the geotagged audio signals, where noise compensation is performed on the audio signal that corresponds to the utterance using the noise model that has been generated for the particular geographic location. | 10-20-2011 |
| 20110288868 | DISAMBIGUATION OF CONTACT INFORMATION USING HISTORICAL DATA - Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for disambiguating contact information. A method includes receiving an audio signal, generating an affinity score based on a frequency with which a user has previously communicated with a contact associated with an item of contact information, and further based on a recency of one or more past interactions between the user and the contact associated with the item of contact information, inferring a probability that the user intends to initiate a communication using the item of contact information based on the affinity score generated for the item of contact information, and generating a communication initiation grammar. | 11-24-2011 |
| 20110289516 | Registering an Event - A computer-implemented method for registering an event includes detecting occurrence of at least one event to be registered in a sequence. The sequence is to have entries for occurred events, each of the entries being a number indicating at least one of the occurred events and being associated with an aggregation number reflecting a number of times the entry has been aggregated within the sequence. The method includes identifying a new entry for extending the sequence, the new entry comprising a first number corresponding to the detected at least one event. The method includes revising the sequence by adding the numbers of at least two entries whose respective aggregation numbers satisfy a criterion for aggregation. The method includes storing the revised sequence. | 11-24-2011 |
| 20110295590 | ACOUSTIC MODEL ADAPTATION USING GEOGRAPHIC INFORMATION - Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for enhancing speech recognition accuracy. In one aspect, a method includes receiving an audio signal that corresponds to an utterance recorded by a mobile device, determining a geographic location associated with the mobile device, adapting one or more acoustic models for the geographic location, and performing speech recognition on the audio signal using the one or more acoustic models model that are adapted for the geographic location. | 12-01-2011 |
| 20110307253 | Speech and Noise Models for Speech Recognition - An audio signal generated by a device based on audio input from a user may be received. The audio signal may include at least a user audio portion that corresponds to one or more user utterances recorded by the device. A user speech model associated with the user may be accessed and a determination may be made background audio in the audio signal is below a defined threshold. In response to determining that the background audio in the audio signal is below the defined threshold, the accessed user speech model may be adapted based on the audio signal to generate an adapted user speech model that models speech characteristics of the user. Noise compensation may be performed on the received audio signal using the adapted user speech model to generate a filtered audio signal with reduced background audio compared to the received audio signal. | 12-15-2011 |
| 20120022675 | PREDICTIVE PRE-RECORDING OF AUDIO FOR VOICE INPUT - Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for providing predictive pre-recording of audio for voice input. In one aspect, a method includes establishing, as input data, state data that references a state of a mobile device and sensor data that is sensed by one or more sensors of the mobile device, applying a rule or a probabilistic model to the input data, inferring, based on applying the rule or the probabilistic model to the input data, that a user of the mobile device is likely to initiate voice input, and invoking one or more functionalities of the mobile device in response to inferring that the user is likely to initiate voice input. | 01-26-2012 |
| 20120022860 | Speech and Noise Models for Speech Recognition - An audio signal generated by a device based on audio input from a user may be received. The audio signal may include at least a user audio portion that corresponds to one or more user utterances recorded by the device. A user speech model associated with the user may be accessed and a determination may be made background audio in the audio signal is below a defined threshold. In response to determining that the background audio in the audio signal is below the defined threshold, the accessed user speech model may be adapted based on the audio signal to generate an adapted user speech model that models speech characteristics of the user. Noise compensation may be performed on the received audio signal using the adapted user speech model to generate a filtered audio signal with reduced background audio compared to the received audio signal. | 01-26-2012 |
