Speech Recognition TRIZ Cases
- Analog-to-Information Voice Recognition Sensor
A2I sensor extracts sparse sound features directly from analog signals to enable continuous voice command recognition.
- Mobile Speech Recognition Noise Filtering via Wireless Beacons
A mobile device filters audio noise using wireless beacon signals to enhance speech recognition accuracy.
- Personalized Speech Recognition Model Using Group Scale Matrices
Applying group scale matrices to specific model layers personalizes speech recognition accuracy while maintaining shared backbone versatility.
- N-best list rescoring for speech recognition latency
Rank-based rescoring of speech hypotheses using dynamic semantic models reduces peak RAM and improves user response time.
- Adaptive Voice Recognition Presentation Control
A presentation control unit adjusts voice recognition result separation based on context.
- Voice Activity Detection for Communication Session Transcription
A transcription system monitors audio streams to detect inactive voice periods and stops sending data during those intervals.
- ASR Filler Model for Wake-Up Phrase Exclusion
A filler model identifies phonemes in speech signals to exclude wake-up phrases from command processing.
- Speech Recognition Using Dynamic Language Model Weighting
Dynamic language model weighting adapts to varying contexts and domains, improving recognition accuracy while maintaining processing efficiency.
- Dialog Detector Using Multi-Scale Context Windows
Multi-scale context windows extract rhythmic features to distinguish speech from singing voices, reducing false alarms in real-time applications.
- Voice Classification via Resonant Frequency Analysis
Controller extracts resonant frequency features from voice samples to generate unique user profiles for machine learning classification.
- Speech Recognition Database Search Using Phonetic Clustering
Phonetic clustering segments large databases to reduce vocabulary search time while maintaining coverage of unknown entries and pronunciation variations.
- Hybrid Controller for ASR Latency and Accuracy Trade-off
A hybrid controller manages speech recognition processing between local and remote servers on mobile devices.
