Context-Based Interactive Plush Toy Speech Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interactive toys lack the ability to respond contextually to spoken words within literary works, such as books or movies, without requiring users to know specific triggering phrases, and struggle to differentiate between triggering and non-triggering phrases effectively.
Innovation Solution
An interactive toy system that includes a speech recognition unit to analyze spoken words and activate pre-programmed responses based on selectively placed triggering phrases within literary works, allowing for context-based interactions without user knowledge of the triggering phrases, and utilizing a combination of phoneme contrast to minimize false positives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If speech recognition is used to detect triggering phrases, then interactive response capability is improved, but false positive detection increases
Solution Approach 1:
The patent applies local quality by making triggering phrases phonemically distinct from surrounding text. Specific phoneme combinations are selected for triggering phrases that contrast with the phonetic patterns of non-triggering phrases, creating localized acoustic fingerprints that improve detection reliability while maintaining interactive responsiveness.
Solution Approach 2:
The patent implements preliminary action by pre-processing and analyzing the phonetic structure of literary text before deployment. Triggering phrases are selectively identified and marked in advance based on their phoneme contrast properties, allowing the speech recognition system to be pre-configured with optimal detection parameters for those specific phrases.
2Measurement precision
If triggering phrases are selectively placed in literary works, then speech recognition accuracy is improved, but user awareness of triggering phrases decreases
Solution Approach 1:
The patent extracts triggering phrases as a separate functional layer from the literary text. These phrases are selectively placed within the narrative but are not visually distinguished or highlighted, allowing them to be extracted by the speech recognition system based on phonemic patterns while remaining invisible to the user, thus maintaining both accuracy and narrative immersion.
3Reliability
If phoneme contrast is used to differentiate triggering phrases, then false positives are minimized, but complexity of phrase selection increases
Solution Approach 1:
The patent changes the phonemic parameters of triggering phrases to create acoustic distinctiveness. By selecting phrases with specific phoneme combinations that contrast with surrounding text, the system transforms ordinary text selection into a phonetically optimized detection target, improving reliability while managing selection complexity through systematic phoneme analysis.

AI summary
An interactive toy for interacting with a user while a story is being read aloud from a book or played from a movie/video. The toy includes a speech recognition unit that receives and detects certain triggering phrases as they are read aloud or played from a companion literary work. The triggering phrase read aloud from the book or played in the movie/video may have independent significance or may only have significance when combined with other phrases read aloud from the book or played in the movie/video.
