LAB 1: Recording Speech in a Sound-Treated Room, and Spectral Analysis and Waveform Editing by Computer

Labs: 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17

The main purpose of this laboratory is to begin getting familiar with the various speech analysis and editing tools that are available in the Speech Group.

  • You will record speech material for use in future labs.
  • You will digitize utterances and make spectrograms.

Here are the resources that you will need:

Lab 1 Handout (PDF)

The speech material to be recorded is listed in the lab handout. If you do not have access to tools to make the recordings, you can download example recordings.

The Tools

  • record - the recording software (VAX).
  • lspecto - used to make and print spectrograms (Vax or UNIX®/Linux®).
