Spanish in numbers
Spanish has about 519 million native speakers — second only to Mandarin — and is official in 21 countries; Mexico has the most native speakers.
Accents and recognition
Spain's 'th' sound for c and z, the softened final 's' of Caribbean speech and the 'sh' of Rioplatense ll/y all trip up weaker speech recognition. Clean, close-mic audio is the best defence.
