Risk is inherently involved in moving large amounts of data, and any PCI contained in the data increases that risk. Yet system migrations and technology upgrades necessitate the movement of large volumes of data. To reduce risk when preparing for a data migration, eliminating PCI is imperative, and Automatic Speech Recognition (ASR) technology can help. Where manually finding and removing PCI from stored audio data would be prohibitively costly and time-consuming, using ASR allows Contact Centers to clean millions of hours of recordings in days, not months. With an ASR solution, Contact Centers can efficiently detect and redact PCI and other sensitive data from stored files, with manual involvement required only for the ASR engine setup and implementation.
