New pending patent applications are published on Thursdays by the USPTO. Today's Spotlight Applications concern aspects of digital fingerprinting and digital watermarking. Assigned to Microsoft, the first application disclose techniques for real-time emotion recognition from audio signals. Assigned to The Nielsen Company, the second application disclose techniques for using audio watermarking for people monitoring.
20160019915, "Real-time emotion recognition from audio signals," assigned to Microsoft.
Systems, methods, and computer-readable storage media are provided for recognizing emotion in audio signals in real-time. An audio signal is detected and a rapid audio fingerprint is computed on a user's computing device. One or more features is extracted from the audio fingerprint and compared with features associated with defined emotions to determine relative degrees of similarity. Confidence scores are computed for the defined emotions based on the relative degrees of similarity and it is determined whether a confidence score for one or more particular emotions exceeds a threshold confidence score. If it is determined that a threshold confidence score for one or more particular emotions is exceeded, the particular emotion or emotions are associated with the audio signal. As desired, various action then may be initiated based upon the emotion/emotions associated with the audio signal.
20160019901, "Audio watermarking for people monitoring," assigned to The Nielsen Company, LLC.
Methods, apparatus, systems and articles of manufacture (e.g., physical storage media) to utilize audio watermarking for people monitoring are disclosed. Example people monitoring methods disclosed herein include determining, at a user device, whether a first trigger condition for emitting an audio watermark identifying at least one of the user device or a user of the user device is satisfied. Such example methods also include, in response to determining that the first trigger condition is satisfied, providing a first audio signal including the audio watermark to an audio circuit that is to output an acoustic signal from the user device.
