SPEECH ACOUSTIC Meaning and
Definition
-
Speech acoustic refers to the specific qualities and characteristics of sounds produced during speech. It involves the analysis and understanding of the physical properties of speech sounds, such as their frequencies, durations, intensities, and spectral content. The field of speech acoustics seeks to examine and explain how these various acoustic features contribute to the perception and production of speech.
Speech acoustic analysis typically involves the use of specialized equipment and software to measure and evaluate the acoustic properties of speech sounds. Researchers and speech-language pathologists utilize these tools to study speech disorders, assess speech intelligibility, and develop strategies for speech enhancement and rehabilitation.
The frequency content of speech sounds, often described using spectrograms, helps distinguish different speech sounds and phonetic elements. Vowels, for example, are characterized by their specific formants or resonating frequencies, while consonants have varying levels of high-frequency noise.
Voice onset time (VOT) is another crucial acoustic parameter used to differentiate between voiced and voiceless consonants. Intensity, or loudness, provides information about stress and emphasis in speech, while duration helps perceive distinct phonemes and prosodic features like syllable length and rhythm.
Understanding speech acoustic properties is essential for various applications, including automatic speech recognition systems, speech synthesis, and acoustic modeling for communication devices. Researchers continue to investigate how these acoustic cues influence speech perception, language production, and the diagnosis and treatment of speech and language disorders.

Etymology of SPEECH ACOUSTIC
The word "speech" can be traced back to the Old English word "spǣc", which means "discourse" or "expression". In turn, this word has Germanic roots, ultimately deriving from the Proto-Indo-European root "*speḱ-", which means "to speak" or "to talk".
The word "acoustic" is derived from the Greek word "akoustikos", which means "related to hearing". It originates from the Greek word "akouein", which means "to hear".
Therefore, the term "speech acoustic" combines the word "speech", referring to communication through spoken words, with "acoustic", pertaining to the sounds, frequency components, and physical properties of sound waves associated with speech.
