Speech Recognition TRIZ Cases
- Wearable Word Counter Using Syllable Detection
A portable device detects spoken syllables and calculates word counts for real-time transmission.
- Speech Recognition Wildcard Threshold Adjustment
Dynamic threshold adjustment via wildcard matching reduces unnecessary rejections of correct speech, boosting worker productivity.
- Vocal Tract Length Normalization Codebooks for Speech Recognition
Precomputed codebooks store speaker-specific normalization factors, reducing computational time while maintaining speech recognition accuracy.
- Voice Command Definition File for Application Launch
A voice command definition file declaratively maps utterances to application navigation paths and execution commands.
- Voice Recognition Server Integration Device
A voice recognition server integration device coordinates general-purpose and specialized servers to process speech inputs.
- Conditional Wake Word Engine for Playback Devices
A command keyword engine detects voice inputs locally on playback devices to execute specific functions without cloud dependency.
- Speech Processing User Identification via Serial Number Association
A speech processing system links device serial numbers to user profiles for identity verification.
- Phase Inversion for Wake Word Detection in Audio Playback
Phase inversion merges inverted speaker waveforms with microphone input to cancel interference and detect wake words accurately.
