This simulation creates a more realistic approximation of what a hypothetical voiceless glottal trill might sound like if it were physiologically possible to produce, in the context: /a/ + [voiceless glottal trill] + /a/.
Explanation
This enhanced simulation creates the following sequence:
- A vowel /a/ using a detailed formant-based synthesizer with realistic vocal tract modeling
- A simulated voiceless glottal trill created by modeling rapid airflow pulsation through a nearly-closed glottis with turbulent noise
- Another vowel /a/ to complete the sequence
Key improvements in this simulation:
- More accurate vocal tract resonance modeling for more human-like vowels
- Micro-variations in pitch and amplitude (jitter and shimmer) to simulate natural voice
- Enhanced glottal pulse modeling based on the Liljencrants-Fant (LF) model
- Smoother transitions between sound components
- Realistic breath noise simulation
- Voice type presets (male, female, child) with appropriate formant structures
Since a true voiceless glottal trill is physiologically challenging (the vocal folds can't simultaneously vibrate for trilling while remaining voiceless), this is an approximation of what such a sound might theoretically sound like if it could be produced.
