Stereophonics frontman Kelly Jones has revealed he had to relearn how to sing by practising multiple vocal exercises after having surgery on his throat.
The star told the High Performance podcast he had a growth removed from his vocal cords.
Jones (46) said recovery had been a "very slow process" and he had to do lots of exercises with his voice to get it back to normal.
"I couldn't speak for about three days and then I could speak for two minutes and then I could speak for five minutes," he said, discussing how he felt after his operation.
"I was just reading like a chapter of a book out loud and then stopped talking.
"So it was quite a strange process. Then it was about learning how to sing again.
"I just had to go through all this very, very slow process, really, and try to regain the strength and the thing that's going to give me my whole kind of life."
He said the growth, called a trauma polyp, "could have been done by a bad cough or shouting at the football".
Jones also said he needed to take a break from the Stereophonics.
"I've clearly started to show people other elements of my talent, my personality, whatever you want to call it, even though I've been trying to do that through the brand of Stereophonics for 25 years, by making every album completely different and trying to change the sound," he said.
Jones described the band as an "amazing thing", but admitted: "I thought I was needing to walk away from it at one point."
He said he realised he was "not quite fulfilled", but now has much greater freedom with his work.
"I can go over there and do this project with these guys from Texas. Or I can go over here and do this other thing," he said.
"I can grow and get fulfilment from these other projects, which will only ignite the main gig."
