The album received mixed reviews from
music critics, some of whom complimented Jessie J's confidence and vocals and the overall production, whilst others criticised the songs for being "generic". Joanne Dorken from
MTV gave it 4 out 5 stars saying that Jessie was "back with a bang!" and said J's "fans were in for a treat", praising tracks like "Ain't Been Done", "Fire", "Masterpiece" and "Sweet Talker", adding that "Overall, Jessie's third offering sees her going back to basics, while also teaming up with a whole hoard of songwriters (52 in total) to craft her more grown-up, more honest sound."
The Guardian gave the album a positive review, stating that "[J] constructed
Sweet Talker to fit a gap somewhere between Beyoncé and Pink", adding that "it's notable that the best moments come when she uncouples herself from it and just sings for the joy of it, as on the brilliant, fizzy pop banger 'Bang Bang', a deserved No 1 this summer".
Slant Magazine was more critical towards the album, giving it a mixed review, praising the first four tracks on the album but stating that "If all Jessie's label wanted was a few bangers, they could have saved themselves some time and money by tacking them onto a repackaged version of Alive and calling it a day". Katherine St. Aspah of
Time was harsher still, claiming that the album "solved the problem of doing everything right [to only moderate success]", and comes across as "slapdash and retooled to an inch of its life". Aspah did reiterate that "the one distinguishing factor of the Jessie J Brand, as demonstrated on Sweet Talker, is that she can sing", but then went on to clarify that it seemed "a curious statement to make in 2014, as the year's biggest divas, our Beyoncés and Arianas, aren't short on chops".
Slant Magazine named it the eighth worst album of 2014. ==Commercial performance==
