Despite many improvements in the quality of voice calls on mobile networks, such as Enhanced Full Rate (EFR), they are still not broadcast quality. In some scenarios, journalists or undercover police officers with portable professional broadcast-quality microphones and amplifiers capture interviews with people or radio reports that they have dictated and need to send this information back to their radio or police station. Leaving a mobile phone on or dictating to a mobile phone would not give sufficient voice quality to enable that transmission to be broadcast or analyzed for the purposes of background noise analysis or voice printing, where the speech autograph is taken and matched against those in police storage. Because even short voice clips occupy large file sizes, GPRS or other high-speed mobile data services are needed.
