acoustic features

Acoustic features are measurable characteristics of sound, especially speech, that help describe and analyze how it sounds. They include elements like pitch (how high or low the voice is), loudness (volume), tempo (speed), and timbre (quality or tone). These features allow us to understand differences in speech, recognize speakers, or detect emotions. Think of acoustic features as the detailed “traits” of sound that can be objectively measured, much like how colors can be described by hue, saturation, and brightness. They are essential in fields like linguistics, speech therapy, and voice recognition technology.
