DETECTING NEAR MATCHES TO A HOTWORD OR PHRASE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240055002 titled 'DETECTING NEAR MATCHES TO A HOTWORD OR PHRASE
Simplified Explanation
The patent application describes techniques for identifying a failed hotword attempt. The method includes the following steps:
- Receiving first audio data.
- Processing the first audio data to generate a first predicted output.
- Determining that the first predicted output satisfies a secondary threshold but does not satisfy a primary threshold.
- Receiving second audio data.
- Processing the second audio data to generate a second predicted output.
- Determining that the second predicted output satisfies the secondary threshold but does not satisfy the primary threshold.
- In response to both the first and second predicted outputs satisfying the secondary threshold but not the primary threshold, and the first and second spoken utterances satisfying temporal criteria relative to each other, identifying a failed hotword attempt.
- In response to identifying the failed hotword attempt, providing a hint that is responsive to the failed hotword attempt.
Potential applications of this technology:
- Voice recognition systems: This technology can be used in voice assistants or voice-controlled devices to improve the accuracy of hotword detection and prevent false activations.
- Speech analytics: The techniques described in the patent application can be applied in speech analytics systems to identify failed hotword attempts and provide feedback to users.
Problems solved by this technology:
- False activations: The technology helps to reduce false activations of hotword detection systems by accurately identifying failed hotword attempts.
- User frustration: By providing a hint or feedback in response to a failed hotword attempt, the technology can help users understand why their command was not recognized, reducing frustration.
Benefits of this technology:
- Improved accuracy: The techniques described in the patent application improve the accuracy of hotword detection systems by distinguishing between successful and failed hotword attempts.
- Enhanced user experience: By providing feedback or hints, the technology enhances the user experience by helping users understand and correct their failed hotword attempts.
Original Abstract Submitted
techniques are described herein for identifying a failed hotword attempt. a method includes: receiving first audio data; processing the first audio data to generate a first predicted output; determining that the first predicted output satisfies a secondary threshold but does not satisfy a primary threshold; receiving second audio data; processing the second audio data to generate a second predicted output; determining that the second predicted output satisfies the secondary threshold but does not satisfy the primary threshold; in response to the first predicted output and the second predicted output satisfying the secondary threshold but not satisfying the primary threshold, and in response to the first spoken utterance and the second spoken utterance satisfying one or more temporal criteria relative to one another, identifying a failed hotword attempt; and in response to identifying the failed hotword attempt, providing a hint that is responsive to the failed hotword attempt.
