äänneperäiset

äänneperäiset is a Finnish term that translates to "sound-based" or "phonetic" in English. It is primarily used in linguistics and phonetics to describe phenomena, analyses, or classifications that are derived from or concerned with the actual sounds of speech. This contrasts with analyses that might be based on grammatical categories, orthography (spelling), or semantic meaning.

In phonetics and phonology, referring to something as äänneperäinen emphasizes that the discussion or classification is rooted in the acoustic properties of speech sounds, their articulation, or their perception. For example, an äänneperäinen classification of vowels would consider their formant frequencies and tongue position, rather than their traditional vowel letter representation. Similarly, an äänneperäinen analysis of a language would focus on the inventory of its distinct speech sounds (phonemes) and their variations (allophones) as they are produced and heard, not necessarily as they are written.

The term can also extend to other fields where sound plays a role. For instance, in musicology or acoustics, an äänneperäinen approach would prioritize the physical characteristics of sound waves. In lexicography, while most entries are based on meaning and spelling, an äänneperäinen perspective might consider how the pronunciation of a word influences its usage or evolution. Essentially, whenever the focus is squarely on the "sound" aspect itself, the term äänneperäinen applies.
