Taf to Pronounce

"The primary difference between Sefardi and Ashkenazi consonants is that the Sefardi pronunciation of the letter Taf without a vowel point is Taf, while the Ashkenazi pronunciation is Saf." (Artscroll transliteration)

But when reading the Shema, we must be careful not to soften hard consonants in this way, so Taf must be pronounced as Taf.
