Canary Islands, and nearly all of Latin America have only (seseo). Some speakers in southernmost Spain (especially coastal Andalusia) have only (a consonant similar to ) and not (ceceo). This "ceceo" is not entirely unknown in the Americas, especially in coastal Peru. The phoneme has three different pronunciations ("laminal s", "apical s" or "apical dental s") depending on dialect. The word distinción itself is pronounced with in varieties that have it. The phonemes and are laminal denti-alveolar (). The phoneme becomes dental before denti-alveolar consonants, while remains interdental in all contexts. Before front vowels , the velar consonants (including the lenited allophone of ) are realized as post-palatal . According to some authors, is post-velar or uvular in the Spanish of northern and central Spain. Others describe as velar in European Spanish, with a uvular allophone () appearing before and (including when is in the syllable onset as ). A common pronunciation of in nonstandard speech is the voiceless bilabial fricative , so that fuera is pronounced rather than . In some Extremaduran, western Andalusian, and American varieties, this softened realization of , when it occurs before the non-syllabic allophone of (), is subject to merger with ; in some areas the homophony of fuego/juego is resolved by replacing fuego with lumbre or candela.

In addition, occurs in Rioplatense Spanish as spoken across Argentina and Uruguay, where it is otherwise standard for the phonemes to be realized as voiced palato-alveolar fricative instead of , a feature called "zheísmo". In the last few decades, it has further become popular, particularly among younger speakers in Argentina and Uruguay, to de-voice to ("sheísmo"). Consonant neutralizations Some of the phonemic contrasts between consonants in Spanish are lost in certain phonological environments, and especially in syllable-final position. In these cases the phonemic contrast is said
