no difference in constriction degree main difference in duration

current study further investigate the nature of the interaction between spirantization and s-aspiration in Western Andalusian

both processes are non-categorical spirantization (deocclusivization) as a result of gestural reduction s-aspiration (assimilation) as a result of gestural reduction and overlap role of the temporal dimension

current study 3 types of data

discussion acoustics

temporal difference between single voiced stop and s+voiced stop

temporal difference between stops and fricatives (independent of voice) rate difference

discussion airflow

rate differences not significant overall but probably so for fricatives

significant difference between spirantized stop and voiced fricatives

spirantized stops lowest values

discussion perception

correct differentiation between spirantized voiced stops and voiced fricatives very low identification rate, mostly velars

perhaps problems with methodology segmentation manipulation
