Voice assistance system, method, and computer program for voice-based support

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention is a voice assistance system that supports users through speech-based interaction. It can recognize spoken language and determine if the spoken input is intended for the system. If so, it processes the linguistic content and performs a support function accordingly. The system adaptively improves its accuracy by analyzing uncertainties or errors in past interactions, using both the content and prosodic (tone, rhythm, etc.) features of speech. This adaptive mechanism enables the voice assistant to better discern when a user is actually addressing it, even in ambiguous scenarios.

Use CasesContent extracted from patent full text and abstract with AI.

• Smart home control (lights, devices, appliances) via voice commands
• Hands-free operation in vehicles for navigation or controls
• Voice-enabled customer service kiosks or call centers
• Personal assistant features in mobile devices or computers
• Accessibility tools for individuals with mobility or vision impairments
• Industrial environments for hands-free machinery or system control

• Interactive educational tools and toys that respond to speech

BenefitsContent extracted from patent full text and abstract with AI.

• Improved reliability in understanding whether a user is addressing the voice assistant, reducing false activations and missed commands
• Adaptive learning from past mistakes or uncertainties, resulting in better recognition over time
• Enhanced user experience through more accurate system responses and fewer unnecessary interruptions
• System can leverage prosodic (tone, accent, rhythm) and linguistic information for more robust intent detection
• Supports a variety of potential output/feedback modes (audio, visual, haptic) for user confirmations
• Versatility across a wide range of devices and application domains
• Facilitates hands-free interaction, increasing convenience and accessibility

Patent Abstract

The invention relates to a voice assistance system for the voice-based support of a user. The voice assistance system is designed, in accordance with the type in question, to recognize voice acoustics and to determine whether or not the recognized voice acoustics were directed to the voice assistance system. If the voice acoustics were directed to the voice assistance system, a support function is performed by the voice assistance system in accordance with the linguistic content of the voice acoustics. The invention also relates to a method and a computer program therefor.
