Acoustic phonetics is the study of the physical properties of speech sounds as they travel through the air. It focuses on how sound waves are produced, transmitted, and perceived in spoken language. Here's a quick breakdown:
Core Concepts
- Sound waves: Vibrations created by vocal cords and air movement
- Frequency & amplitude: Key parameters defining pitch and volume
- Spectral analysis: Breaking down sounds into their frequency components
Tools & Techniques
- Waveform visualization: Observing sound wave patterns
- Spectrograms: Color-coded representations of frequency over time
- Formant analysis: Identifying vowel characteristics through resonance frequencies
Applications
- Speech recognition systems (e.g., Siri, Alexa)
- Forensic linguistics for voice identification
- Language learning tools for pronunciation analysis
