ATLAS OF LANGUAGE

Contextual explanation · NAV-G04-004

Speech stream

This explanation addresses the term in its originating context. It is not an additional canonical Atlas profile.

Explanation

Speech stream names the temporal unfolding of spoken language before or during its analysis into distinguishable units. The metaphor emphasises that sounds are not ready-made beads separated by complete pauses. Articulatory gestures overlap, and acoustic cues to one unit may extend across neighbouring intervals. Speech is nevertheless neither uniform nor inherently unsegmentable. Pauses, closures, rhythm and prosody provide different segmentation cues. In the coarticulation context, the task is to relate temporal continuity to a justified analysis of linguistic units without directly projecting written divisions onto the signal.

Movement of thought

1. Inspect a recording as a temporal sequence. 2. Mark acoustic changes. 3. Look for overlapping articulatory cues. 4. Justify proposed segment boundaries. 5. Compare the different levels of analysis.

Example

In the English word shoot, lip rounding for the vowel can begin during the preceding [ʃ]. Articulatory cues therefore extend across the boundary of an individual sound segment.

Counter-test

A written space does not guarantee silence in speech. Conversely, a pause can interrupt an already begun unit.

Scientific use case

Phonetic research can align acoustic patterns with articulatory movement over time.

Effect

The term clarifies the relationship between continuous realisation and analytical segmentation.

Resonance

A boundary visible in writing need not stand still in sound.

Distinction

Distinguish the speech stream from spelling, uniform noise and any predetermined segmentation.
