Pre-requisites
- 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.
- 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'
Recording sentences
- Start Audacity.
- Make sure your microphone volume in Audacity is set to 1.0.
- Then click Record (i.e. the red circle button) and begin speaking in your normal voice for a few seconds, and then click Stop (i.e. the yellow square button). Look at the Waveform Display for the audio track you just created. The Vertical Ruler to the left of the Waveform Display provides you with a guide to your audio levels. Try to keep your recording levels between 0.5 and -0.5, averaging around 0.3 to -0.3. It is OK to have a few spikes go outside the 0.5 to -0.5 range, but avoid having any go beyond the 1.0 to -1.0 range, as this will generate distortion. If necessary, adjust Audacity's microphone volume to keep your audio within the proper ranges.
