Test Increasingly Complex Sets of Audio Devices

​With the growing popularity of Internet of Things devices worldwide, many electrical products are adopting voice commands as their user interface. This shift means that acoustic and audio test challenges are likely to impact more products than ever before. Test teams must meet extended test coverage requirements to ensure product quality while maintaining throughput and operational efficiency. For a solution to meet these sorts of demands, it must:


  • Provide complete coverage for current and future test requirements
  • Operate within the expected cycle-time limit
  • Design, develop, and deploy within a production schedule
  • Fit into manufacturing processes both physically and operationally
