Citing Cosby's frailty and blindness, Cosby's lawyers had asked for house arrest rather than prison time.
The judge, on Tuesday, ruled on Cosby's sex-offender status after a defence psychologist, Timothy Foley, testified that the chances of the comedian committing another sex offense are "extraordinarily low" because he is old, legally blind and needs help getting around.
Around 60 women, many of them onetime aspiring actresses and models, have publicly branded Cosby as a calculating, serial predator who plied victims with sedatives and alcohol to bed them over four decades. But in April, when prosecutors claimed he had a private plane and asked the judge to revoke his bail, Cosby stood up in court and yelled, "He doesn't have a plane, you a**hole", referring to himself in the third person. His once family-friendly reputation, sparked by his portrayal of Dr. Cliff Huxtable in the 1980s sitcom,"The Cosby Show", eclipsed by the slew of allegations. "The jury thinks otherwise", District Attorney Kevin Steele said.
Ms Constand wrote that Cosby's 2004 attack on her was just "the tip of the iceberg" for the suffering that followed.
A forensics expert who analyzed the recording told Cosby's defense team that it was "not a true representation of the original content or conversation", according to Camille Cosby's statement. It's not immediately clear if Cosby will actually be sentenced the same day. O'Neill allowed five of them to testify at trial, while others came to watch the court proceedings.
Under that designation, Cosby will have to undergo monthly counselling and register as a sex offender with police for the rest of his life.
The label will not affect the length of a potential prison sentence.
State sentencing guidelines, which are not mandatory, recommend a sentence between two and four years, Mr Chanenson said.
Cosby's first trial in 2017 ended in a mistrial when jurors could not reach a verdict.
Actress Janice Dickinson, who has also accused Cosby of sexual assault, laughed as the former entertainer was led from the courtroom. "Eighty-one-year-old blind men who are not self-sufficient are not a danger, unless perhaps to themselves". "I am glad that Bill Cosby was convicted".
Cosby could have served a 30-year sentence, as each of his crimes would result in 10 years of imprisonment.
