Phonetics and Acoustic Properties of Speech Sounds

These flashcards cover the key concepts related to the acoustic and articulatory properties of speech sounds as discussed in the lecture.

Voicing

Refers to the vibration of the vocal cords during the production of speech sounds.

Articulation

The physical process of producing sounds by coordinating the movement of the vocal tract, which includes the tongue, lips, and palate.

Stop consonants

Speech sounds produced by obstructing airflow in the vocal tract, followed by a burst of sound.

VOT (Voice Onset Time)

The duration of time between the release of a stop consonant and the onset of voicing.

Burst noise

A spike of energy that occurs after the release of a stop consonant.

Silence gap

The brief period of no sound that occurs before a stop consonant is released.

Glottal stop

A type of consonantal sound made by obstructing airflow in the vocal tract with the glottis.

Voice bar

The visual representation of sound in a spectrogram indicating voiced sounds during stops.

Aspiration

The burst of breath that follows the release of certain voiceless consonants.

F1 and F2 transitions

Formant transitions important for distinguishing vowel sounds in speech.
