Speech Synthesis TRIZ Cases
- Streaming Text TTS Punctuation Model Latency
A punctuation model adds grammatical marks to streaming text sub-strings before speech synthesis processing.
- Pitch Modification Ratio Thresholds for Speech Synthesis Speed
A pitch modification ratio determines whether concatenative speech synthesis applies complex frequency-domain algorithms or simpler windowing techniques.
- Speech Synthesis Dictionary Delivery Device for Network-Constrained Terminals
A speech synthesis dictionary delivery device switches between high-fidelity and compact acoustic models based on terminal requirements.
- Text to Speech Synthesis with Alternative Unit Selection
A unit selection system derives target sequences and presents alternative speech waveforms for operator choice.
- Dynamic Voice Profile TTS for Personalized Speech Output
Machine learning generates voice profiles approximating a sender's vocal traits, resolving generic speech output confusion in IoT messaging systems.
- Glottal Pulse Model Excitation Signal Formation
Segment voice source signals into glottal pulses and join edges to preserve low-frequency information in synthetic speech.
- Secure Text-to-Speech Synthesis with Voiceprint Authentication
Server-side authentication controls access to originator voiceprints, preventing unauthorized speech synthesis while maintaining naturalness.
- Speech Signal Substitution for Low Bit Rate Quality
A signal processing module replaces distorted speech segments with substitute audio data to restore clarity.
- Speech Synthesis Device User Dictionary Control
A speech synthesis device uses a control unit to determine user dictionary usage based on the active function.
- Speech Synthesis Switching Between Online and Offline Systems
A speech synthesis system switches between online and offline engines based on network availability.
- Audio Avatar Creation from Human Voices
Voice analysis module transforms subject voice to mimic target voice while preserving verbal message content.
- Audible Social Network Notifications for Inattentive TV Users
A television converts social network text into audible alerts when user engagement drops below a set threshold.
- Crowd-sourced Pronunciation Correction for Text-to-Speech Engines
A text-to-speech engine aggregates user-submitted pronunciation corrections to generate validated hints that improve speech output accuracy.
- Supplemental Phoneset for Speech Synthesis Preselection
A supplemental phoneset enhances unit preselection in speech synthesis engines.
- Multi-Style Speech Synthesis Using Universal Database
Universal speech databases reduce storage space by reusing segments across styles, eliminating the need for separate style-specific libraries.
- Speech Frame Loss Compensation Using Non-Cyclic Pulse Suppression
Detecting non-periodic pulse waveforms in lost frames allows a speech decoder to replace high-amplitude excitation with noise, preventing loud beep sounds.
- Neural Network Audio Conversion Timbre Transfer
Segmented components maintain linguistic content while adopting reference timbre, resolving accuracy-versus-complexity trade-offs.
- Speech Unit Selection via Dual-Cost Lattice Construction
Dual-cost lattice construction balances acoustic continuity with phonetic accuracy, avoiding local minima in large corpora.
