According to one neighbor's testimony, the shots were separated by around 15 minutes:

Oscar Pistorius told: 'You are getting deeper into trouble'

As the trial entered its fourth week, Stipp told the court that she woke up just after 3am on 14 February 2013 hearing three sounds "like gunshots". She and her husband heard a woman screaming, she said, and went outside. The screaming was "loud and clear" and not muffled, she said, although male cries could also be heard.
Stipp said the couple called security and heard what she thought was three more shots 15 minutes after she had first woken up. After the second set of shots there was no more screaming, neither male nor female, reports eNCA.
Stipp, an occupational therapist involved in medico-legal work, said she was "absolutely certain" the screaming she heard was female and repeatedly insisted it was not Pistorius. They had two different pitches, she said.

And here they state FOUR WITNESSES heard a woman screaming:

Four witnesses said they heard a woman's screams – described by one neighbour as "bloodcurdling" – around the time Steenkamp was killed. Yet Pistorius claims he was the only one to cry out once he realised he had shot his girlfriend. Defence lawyer Barry Roux has repeatedly suggested that Pistorius may have screamed like a woman.
