Syllable-final consonant deletion has been widely documented in Eastern Andalusian Spanish, although the effects of consonant deletion on preceding vowels are still unknown. Studies analyzing syllable-final consonants in Eastern Andalusian Spanish have focused on /-s/, disregarding other consonants which are also deleted in this position. The present paper aims to extend this traditional focus by analyzing how /-s/, /-r/ and /-θ/ deletion affects preceding /i/. After analyzing 383 samples of /i/ word-finally and before underlying word-final /s/, /r/ and /θ/ in Western Almería (Eastern Andalusia), it is confirmed that the deletion of these three consonants changes the quality of preceding /i/. Furthermore, the results of a perception test confirm that speakers of Eastern Andalusian Spanish can identify whether or not /i/ is followed by an underlying /-s/, /-r/ or /-θ/ and they can also identify two types of /i/ in isolation: word-final /i/ and /i/ preceding underlying /-r/; this identification occurs at a rate which is statistically significant. It is hypothesized that, apart from vowel height and frontness, a suprasegmental feature could be the perceptual cue used to identify an underlying consonant after a vowel in this variety of Spanish.
