The NYPD will widen its videotaping of interrogations to include all suspects in murder and sexual assault cases.
Police Commissioner Raymond Kelly announced the plan in a private speech to the Carnegie Council on Wednesday.
The NYPD later released a copy of the speech.
The agency started to videotape interrogations last year, but they were limited to felony assault suspects in two precincts.
The commissioner said taping interrogations would "enhance public confidence in the criminal justice system by increasing transparency."
He said electronic recordings will help reduce concern about false confessions and provide a reliable record of an interview.
The commissioner didn't give a timetable for when the recordings would be expanded.
He said the NYPD is seeking a $3 million grant from the nonprofit Police Foundation for the program.
