Pre-requisites

  1. You must have a headset with a mic or a desktop boom mic. Preferably the same mic which will be used for speech recognition on the robot. Built in laptop or desktop mics are not recommended.
  1. Make sure you have Audacity installed. This can be done as follows on linux
sudo apt-get install audacity
  • Open Audacity and configure it as follows
    • In the Edit>Preferences>Devices (or Audio I/O); make sure that you select 'Channels: 1 (Mono)' under the 'Recording' section.
    • In the Edit>Preferences>Quality; make sure that the 'Default Sample Rate' is set to '48000 Hz' and the 'Default Sample Format' is set to '16-bit'
