"I don't know what to say honestly. I fought off a virus a few weeks ago and since then we have travelled across Europe and has such incredible shows. Today in soundcheck I felt fine and was so excited to give Manchester an amazing show tonight, with a special surprise at the end," Smith wrote on Instagram Stories.
"During my third song, I noticed something wrong with my voice. I prayed it was just my voice waking up for the show but into the fourth song I could feel something was really wrong," they added. "I came off stage and have tried everything to get my voice back in gear but it won't."
Smith told fans that they are "honestly heartbroken" that they couldn't finish the concert.

After cutting the show short, Smith canceled a pair of upcoming concerts Thursday. The singer is in the midst of their Gloria tour and was to perform Thursday in Glasgow, U.K., and Saturday in Birmingham, U.K.
Smith is offering refunds for the Manchester, Glasgow and Birmingham shows.
"Due to vocal issues during last night's Manchester performance, regrettably we will be cancelling the rescheduled Birmingham and Glasgow Sam Smith shows," a post from Smith's team reads.
"A spokesperson said 'Doctors have advised due to a vocal cord injury, Sam must have complete vocal rest,'" the team said. "'Sam is heartbroken to have had to cancel these shows but they have been told by doctors that if they keep singing, they will do permanent damage to their voice. If they take some rest they will be able to perform again.'"
