What are the two types of acoustic measures highlighted in speech analysis?

In speech analysis, the two types of acoustic measures highlighted are temporal and frequency measures. Temporal measures refer to aspects of speech that pertain to time, including durations of segments, timing of syllables, and speech rate. This is essential for analyzing the rhythm and speed of speech, which can affect intelligibility and the expressiveness of spoken language.

Frequency measures involve the pitch and harmonics of speech sounds, reflecting the frequency characteristics of the voice and the resonance of the vocal tract. These measures include fundamental frequency (pitch) and formant frequencies, which are crucial for understanding how different speech sounds are produced and perceived.

Both temporal and frequency measures provide a comprehensive framework for analyzing speech, allowing researchers and clinicians to assess various aspects of phonation and articulation in speech production. This dual approach is fundamental in fields such as speech-language pathology, linguistics, and acoustic phonetics.
